Ninox and Stacker both use AI to generate no-code applications, but they're structured for different pricing habits and different audiences. Ninox is a…
Best for Ninox: Teams that need documented compliance certifications (ISO 27001, GDPR, ISO 9001) and data hosted in Germany, that prefer per-user seat pricing over credit consumption, and that want an indefinitely free plan for small teams (up to 5 users) rather than a time-limited trial.
Best for Stacker: Teams that need unlimited, white-labeled customer-facing portals with custom domains, that want AI able to restructure an entire existing app (not just generate templates), and that need broad third-party connectivity (2,000+ integrations) without per-seat pricing.

Key Differences
Pricing structure: per-seat vs. credit-based
Ninox: Ninox charges per user/month (€25 Team, €40 Business, billed annually), with storage and record limits scaling per user.
Stacker: Stacker charges $50/month for 250 credits on its Standard plan with no per-seat charges, scaling up to $2,000/month for heavier usage.
Per-seat pricing is predictable as headcount is known in advance, while credit-based pricing can flex with usage but is harder to forecast, as Stacker's own documentation acknowledges.
Compliance and hosting documentation
Ninox: Ninox documents ISO 27001, GDPR, and ISO 9001 compliance with German-hosted data centers, plus a founding year (2014) and headquarters (Berlin).
Stacker: Stacker's facts do not document any compliance certifications, founding year, or headquarters.
Documented certifications and a known legal entity/location matter for procurement and data-residency reviews, particularly for regulated industries.
Customer-facing portals
Ninox: Ninox's documented views are internal record-management views (table, form, chart, kanban, maps, calendar); no customer-facing portal feature is documented.
Stacker: Stacker explicitly offers white-labeled, unlimited customer portals with custom domains, even on the Standard plan.
A dedicated customer portal feature signals the platform is designed for external-facing use, not just internal data management.
Integration breadth
Ninox: Ninox's documented integrations are Gmail and Outlook (Workplace collaboration); broader third-party connectivity is not documented.
Stacker: Stacker documents connections to 2,000+ third-party tools.
A large integration catalog reduces the need for custom connectors when building apps that pull from multiple existing systems.
Depth of AI editing
Ninox: Ninox's AI-assisted app building generates apps from user descriptions; advanced AI prompts are gated to the Business plan and above.
Stacker: Stacker's AI can redesign layouts, add features, and restructure entire existing applications on request, and can generate custom code components.
The ability to have AI modify an already-built app (not just generate it once) changes how iterative the build process can be.

Pros & Cons
Ninox
Pros
True relational database engine, more powerful than spreadsheet-style no-code tools for complex data
Native offline-capable apps for macOS, Windows, and iOS, not just a web app
Free plan that never expires, good for testing before committing to a paid tier
Strong library of templates for common business use cases
Popular and well-supported in European markets with local-language support
Cons
Steeper learning curve than pure drag-and-drop tools due to its formula/scripting layer
Smaller ecosystem of third-party integrations compared to Airtable or Power Apps
Per-user pricing can add up quickly for larger teams
Interface and design conventions can feel dated compared to newer no-code competitors
Advanced automation and admin controls are gated behind higher-priced tiers
Credit-based pricing avoids per-seat costs, which suits apps with many external client users
Strong fit for teams already using Airtable or Google Sheets as their data layer
AI prompt-to-app builder speeds up initial app creation
Backed by significant venture funding, including a $20 million Series A from Andreessen Horowitz
Cons
Credit-based pricing can become expensive as usage scales beyond the base tiers
Dependent on underlying data sources like Airtable, which have their own cost and scaling limits
Less suited to highly custom or complex application logic than full-code development
Enterprise pricing is not publicly disclosed and requires contacting sales
Recent rebrand from stackerhq.com to stacker.ai may cause some confusion for existing users
Use Cases
Choose Ninox: Teams that need documented compliance certifications (ISO 27001, GDPR, ISO 9001) and data hosted in Germany, that prefer per-user seat pricing over credit consumption, and that want an indefinitely free plan for small teams (up to 5 users) rather than a time-limited trial.
Choose Stacker: Teams that need unlimited, white-labeled customer-facing portals with custom domains, that want AI able to restructure an entire existing app (not just generate templates), and that need broad third-party connectivity (2,000+ integrations) without per-seat pricing.
Need both: A company that needs an internally governed, compliance-hosted system of record (Ninox, for German-hosted, ISO-certified data) alongside a client-facing portal layer with white-labeled branding and custom domains (Stacker, which documents unlimited customer portals that Ninox does not) could reasonably run Ninox as the backend of record and Stacker as the external-facing layer.
Ninox
Custom CRM for small businesses — Small businesses use Ninox to build a tailored CRM that matches their exact sales process, rather than adapting to a rigid off-the-shelf CRM.
Field team data collection — Teams working in the field, such as inspectors or service technicians, use Ninox's offline-capable mobile apps to collect and sync data without needing constant connectivity.
Departmental workflow apps — Individual departments within larger organizations use Ninox to build lightweight internal tools for tracking inventory, projects, or operations without involving central IT.
Stacker
Internal Operations Tools — Operations teams replace manual spreadsheet workflows with structured internal apps for tracking projects, inventory, or customer records.
Client and Partner Portals — Businesses build secure, branded portals that give external clients or partners controlled access to relevant data.
Custom CRM Replacement — Small businesses use Stacker to build a lightweight custom CRM on top of existing Airtable or Google Sheets data rather than adopting a heavier, generic CRM platform.
