Braintrust — There are two unrelated companies named Braintrust. This profile covers Braintrust (braintrust.dev), an AI observability and evaluation platform founded in 2023 by Ankur Goyal, previously founder of Impira (acquired by Figma), and headquartered in San Francisco. Braintrust helps teams building LLM-powered products and AI agents trace requests in production, run offline evaluations against datasets, score outputs with LLM graders, code, or human review, and catch quality regressions before they reach users. Its eval-first philosophy starts from defining what a good output looks like and measuring against that, rather than only capturing logs and searching after the fact. The platform includes Loop, an AI assistant that analyzes production traces and recommends custom scorers, and Brainstore, a purpose-built data store for querying millions of nested agent traces quickly. In February 2026 the company raised an 80 million dollar Series B led by ICONIQ at an 800 million dollar valuation. Note: this is a different company from Braintrust (usebraintrust.com), a blockchain-based, token-incentivized freelance talent marketplace founded in San Jose in 2018 by Adam Jackson, Gabriel Luna-Ostaseski, and Brian Flynn - do not confuse the two.
Brightpearl — Brightpearl is a cloud-based retail operating system for multichannel retailers and wholesalers, covering inventory management, order management, purchasing, warehousing, CRM, and financial management in one connected platform. Founded in Bristol, UK in 2007 by Chris Tanner and Andrew Mulvenna (originally spun out of their sports retail business, Lush Longboards, as Pearl Software before being renamed Brightpearl in 2010), the company grew into one of the best-known operations platforms for growing ecommerce and wholesale brands. In December 2021, Sage Group plc agreed to acquire the roughly 83 percent of Brightpearl it did not already own for around 299 million pounds (about 340 million dollars total, including its existing 17 percent stake), and the acquisition completed in January 2022. Brightpearl now operates as 'Brightpearl by Sage,' extending Sage's retail and ecommerce financial management proposition, particularly alongside Sage Intacct, while continuing to be sold and supported as a distinct product for product-centric, high-volume retailers and wholesalers rather than being folded into a single unified Sage SKU.
BrowserCat — BrowserCat is a cloud-based headless browser API built for developers who need to run browser automation, such as web scraping, end-to-end testing, PDF generation, and screenshot capture, without hosting and maintaining their own browser infrastructure. Founded in 2023 and operated by Browser Labs LLC, a Delaware corporation doing business as BrowserCat, the service works by letting developers point existing automation tools, including Playwright, Puppeteer, or any client that speaks the Chrome DevTools Protocol, at a managed WebSocket endpoint instead of a locally installed browser. This means teams can keep using the same automation scripts and libraries they already know while offloading the operational burden of running, scaling, and patching headless Chrome instances. BrowserCat is designed to support full, real-user-like browser sessions, including logging into websites, interacting with dynamic content, and completing multi-step workflows, which distinguishes it from simpler, request-based scraping APIs that cannot handle authenticated or highly interactive sites. Pricing follows a usage-based credit model: a free tier includes 1,000 credits per month, with a paid Business plan starting at 50 dollars per month for a larger, lower-cost credit allotment, and additional usage billed per credit beyond plan limits.
Bump — Bump.sh is a modern API documentation and change-management platform that turns OpenAPI and AsyncAPI specification files into always-current, diff-aware developer documentation and API hubs, and is the current, actively developed product behind the Bump name (unrelated to the discontinued Google-acquired Bump contact-sharing app).
Burnermail — Burner Mail (burnermail.io) is a privacy-focused browser extension and email-forwarding service that generates disposable, anonymous email addresses (burners) on demand so users never have to hand their real inbox to unfamiliar websites, newsletters, or online forms. Once installed, its extension detects email input fields and instantly creates a unique burner address that forwards messages straight to the user's real inbox, letting them reply from that burner identity without ever exposing their true address to the sender. If a particular burner starts attracting spam or gets sold to third parties, users can disable that single address without affecting any other account tied to their real email, effectively creating an unlimited set of throwaway identities that can each be individually revoked. Burner Mail says it is trusted by more than 373,000 users and has been covered by outlets including Lifehacker, Wired, and Digital Trends. The company has scaled back or removed parts of its free tier over time, pushing most functionality behind a paid Premium subscription that also unlocks features like connecting a custom domain and routing a single burner to multiple real inboxes for shared or team use, making it best suited to privacy-conscious individuals and small teams rather than large organizations.
Buttondown — Buttondown is a lean, no-frills email newsletter platform built by solo developer Justin Duke, who launched it in July 2017 as a bootstrapped alternative to bloated marketing-automation suites like Mailchimp and ConvertKit. It targets writers, indie developers, and small publishers who want a fast Markdown-first editor, hosted newsletter archives, and a clean sending experience without being upsold on funnels, landing pages, or CRM features they will never use. Buttondown's pricing model is unusual in the email space: rather than forcing everyone into rigid subscriber tiers, it charges based on active subscribers and lets customers add individual capabilities - such as tagging and segmentation, paid subscriptions, surveys and comments, analytics, RSS-to-email, sponsorship tools, or multiple newsletters - a la carte, so a small newsletter only pays for what it actually uses. The company has been notably transparent about its finances, publicly sharing revenue figures as a profitable, bootstrapped business rather than a venture-backed one. Because it also supports paid subscriptions without taking a platform cut, and offers a 50 percent discount to registered 501(c)(3) nonprofits, Buttondown has become popular among independent writers, newsletter-based businesses, and technical bloggers who prioritize simplicity and predictable costs over an all-in-one marketing suite.
C3 — This profile refers to C3.ai (NYSE: AI), the publicly traded enterprise artificial-intelligence software company founded in 2009 by veteran enterprise-software entrepreneur Thomas Siebel (founder of Siebel Systems) - not any of the other, unrelated products that also go by the name 'C3.' The company was originally named C3 Energy and later C3 IoT before rebranding to C3.ai as it shifted from a narrow carbon- and energy-management focus toward a broader enterprise AI platform. C3.ai went public on the New York Stock Exchange in December 2020 and is headquartered in Redwood City, California, with roughly 900 to 1,200 employees depending on the reporting period. Its flagship offering is the C3 AI Platform, now marketed as the C3 Agentic AI Platform, a model-driven development environment that lets large enterprises and government agencies build, deploy, and operate AI and machine-learning applications at scale, alongside a library of prebuilt applications for use cases like predictive maintenance (Reliability), demand forecasting, inventory optimization, supply-chain sourcing, and process optimization. C3.ai sells primarily to large enterprises, government, and defense customers - including long-running relationships with the U.S. Air Force, Department of Defense, and industrial companies like Shell and Baker Hughes - rather than through self-serve signup, so pricing is customized per contract rather than published as fixed plans.
CacheFly — CacheFly is a long-running, privately held content delivery network (CDN) provider that traces its roots to Downloadhosting.com, a file-distribution service for small software developers founded by CTO Matt Levine in 1999; the company launched its CacheFly CDN brand and pioneered TCP Anycast-based content delivery between 2002 and 2005, making it one of the earliest Anycast CDNs in the industry. Now headquartered in the Chicago, Illinois area (with a fully remote team of roughly two dozen employees spread across North America, Europe, and South America), CacheFly positions itself as a premium, boutique alternative to hyperscale CDNs for customers - particularly in media and entertainment, gaming, and ad tech - who need fast, reliable, highly controllable content delivery rather than the lowest possible price. Its network spans more than 75 points of presence across all seven continents, and its proprietary BestHop routing technology automatically selects the fastest path between a customer's origin server and end users. Recent product investments include Advanced Analytics, an EdgeControl JavaScript engine for programmable edge logic, and Terraform integration for infrastructure-as-code CDN management, showcased at NAB Show 2026. Pricing is transparently published, ranging from a free developer tier through usage-based Business and Enterprise tiers to custom, quote-based High Volume plans for petabyte-scale customers.
Cairo-Dock — Cairo-Dock is a free, open-source application launcher and dock for Linux desktops, designed to give users a customizable, animated bar of application icons similar in spirit to the docks found on macOS, but fully skinnable and desktop-environment-agnostic. Originally created by developer Fabrice Rey (known online as Fabounet) and first released in the mid-2000s (commonly dated to around 2007), Cairo-Dock is written in C and rendered using the Cairo graphics library combined with OpenGL, which lets it apply hardware-accelerated animations, reflections, and zoom effects while staying light on CPU usage. It is distributed under the GNU General Public License version 3, meaning the source code is freely available and the project is maintained by a small community of volunteer contributors on GitHub under the Cairo-Dock organization rather than by a commercial company. The dock works alongside virtually any Linux desktop environment (GNOME, KDE, Xfce, and others), supports a large catalog of downloadable themes and applets covering things like a clock, weather, system tray, Wi-Fi status, and email notifications, and can be detached into individual desktop widgets. Version 3.6 brought full Wayland support and HiDPI-aware rendering, keeping the project relevant as Linux distributions have shifted away from the older X11 display server.
Cassandra — Apache Cassandra is a free, open-source, distributed wide-column NoSQL database built to handle massive amounts of data across many commodity servers with no single point of failure. Originally developed at Facebook by Avinash Lakshman and Prashant Malik to power inbox search, it was open-sourced in 2008 and became an Apache Software Foundation top-level project in 2010. Cassandra combines Amazon Dynamo-style distributed architecture with a Google Bigtable-style column-family data model, giving it linear scalability, tunable consistency, and near-zero downtime across data centers and cloud regions. It is not a commercial product or company; it is a community-governed open-source project maintained by contributors from companies like DataStax, Instaclustr, Apple, Netflix, and many independent developers. Cassandra is widely used for write-heavy, high-throughput workloads such as messaging systems, IoT telemetry, time-series data, product catalogs, and recommendation engines where availability and horizontal scale matter more than complex relational queries or strict ACID transactions.
CatchDoms — CatchDoms is an expired and pending-delete domain discovery platform built for domain investors, SEO professionals, and entrepreneurs looking to find valuable dropped or auctioned domains. It aggregates listings from roughly 16-20 domain auction platforms, including GoDaddy, Dynadot, DropCatch, SnapNames, Catched, and Gname, alongside a database of over 100,000 aged ccTLD domains available to register at standard price, adding tens of thousands of newly discovered domains every day. Every domain is automatically enriched with SEO and authority metrics such as Trust Flow, Citation Flow, Domain Authority, backlink counts, referring domains, and Wayback Machine history, so buyers can gauge a domain's value before bidding rather than manually checking each metric across separate tools. CatchDoms was built and is operated by a solo, bootstrapped founder, Samir Belabbes, who previously spent over a decade in SEO and web development and built the tool to solve his own workflow problem of checking a dozen auction platforms and multiple SEO tools every morning. Beyond the web interface, CatchDoms offers a REST API and a Model Context Protocol (MCP) server, letting developers and AI assistants like Claude or Cursor query expired-domain data programmatically or conversationally. Pricing includes a free tier showing limited visible domains, and a paid Pro plan around EUR 39 per month billed annually (EUR 89 per month billed monthly, or EUR 468 per year), with higher Authority and Authority plus tiers adding features like the aged-ccTLD regfee database and founder access.
CatchJS.com — CatchJS is a lightweight JavaScript error tracking, web performance monitoring, and privacy-friendly analytics tool aimed at developers who want a simple, fast alternative to heavier monitoring platforms. Founded in 2018 and based in Trondheim, Norway, CatchJS was built around the philosophy that good developer tools lead to higher-quality products, and it differentiates itself primarily through its footprint: the tracking script is reported to be under 1.8KB after compression, described by the company as up to 20 times smaller than competing error-tracking scripts. Once a single script tag is added to a site, CatchJS automatically captures unhandled JavaScript errors with full stack traces and surrounding context, while also measuring real-user performance metrics such as Largest Contentful Paint, Cumulative Layout Shift, and First Input Delay, alongside simple, privacy-respecting page analytics that avoid invasive user tracking. It is distributed both as a standalone JavaScript snippet for any website and as a dedicated Shopify app, Error Tracking with CatchJS, making it accessible to e-commerce store owners who are not full-time developers. Pricing is tiered by monthly error volume and monitored URL count, starting with a Development plan intended for staging and testing use, scaling to a Production plan for live sites, and topping out with an Enterprise plan for high-traffic applications, all backed by a 14-day free trial.
cDox — cDox is a privacy-first document and spreadsheet collaboration platform positioned as a Google Docs and Microsoft 365 alternative for users who want their data kept out of AI training pipelines and hosted under data-sovereign legal jurisdiction. Built by BFH Labs Inc., a Canadian company, cDox currently hosts all user data on independent bare-metal servers physically located in Montreal, Quebec, governed by Canadian and Quebec law, with plans to expand hosting to additional countries, including France, Germany, the UK, Switzerland, and Australia, through 2027, so users will eventually be able to choose which country's jurisdiction their data lives under. The platform combines word-processing (pages) and spreadsheet (sheets) functionality with real-time collaboration via email invitations, auto-saving, one-click publishing to shareable public links, export options to Markdown, PDF, Word, and CSV, plus features like dark mode, keyboard shortcuts, threaded comments, and REST API access. Its core promise, stated explicitly by the company, is that user content is never used to train AI models and is never extracted or mined for other purposes. cDox targets writers, journalists, researchers, developers, editors, therapists, healthcare providers, nonprofits, and educators, groups for whom data privacy and jurisdictional control matter more than the deepest possible feature set. Pricing is freemium: a Free tier offers 50MB of storage and up to 3 public links, while the Pro tier costs $8 per month or $70 per year and unlocks 500MB of storage and unlimited public links.
Chatterino — Chatterino is a free, open-source, third-party Twitch chat client for Windows, macOS, and Linux, built to be faster and more customizable than Twitch's built-in web chat.

Access is free but gated by a manual approval process to protect shared infrastructure. Codeberg also offers Forgejo Actions, a GitHub-Actions-style alternative, in open alpha.
codenameone.com — Codename One is an open-source, write-once-run-anywhere framework that lets Java and Kotlin developers build truly native mobile apps for iOS, Android, desktop, and web from a single codebase. It was founded in 2012 by Chen Fishbein and Shai Almog, former Sun Microsystems engineers who had previously created the LWUIT toolkit, and it compiles Java bytecode to native platform executables using cloud build servers. The core framework is free and open source, with optional paid cloud-build plans for higher quotas and advanced features.

Contact.do — Contact.do is a link-based contact tool that lets people share a single web link, such as contact.do/username, instead of publishing their real email address online. Messages sent through the link are forwarded to the owner's actual inbox while the underlying email address stays hidden from spammers and bots. It is not a scheduling or booking tool; it has operated as an email-privacy link service since 2018.
Container Registry Service — 'Container Registry Service' is a generic, descriptive term for cloud-hosted or self-hosted repositories that store, version, and distribute container images, most commonly Docker or OCI-format images, so they can be pulled by orchestration platforms like Kubernetes. It is not a single branded product; the term covers offerings such as Docker Hub, Amazon Elastic Container Registry, Google Artifact Registry, Azure Container Registry, GitHub Container Registry, and self-hosted options like Harbor. This entry treats the term generically because no single vendor named exactly 'Container Registry Service' could be verified as the intended product.
Conversion Tools — Conversion Tools (conversiontools.io) is a browser-based file conversion service that converts documents, spreadsheets, images, audio, video, and data files such as JSON, XML, Excel, PDF, and Word between more than 100 formats.
