ForgeCode brings AI pair programming into the terminal, supporting Claude, GPT, Gemini and more. Free tier available; Pro plans start at $20/month.
ForgeCode is an AI coding agent designed to live inside a developer's terminal rather than a separate application window or IDE sidebar. Built by Tailcall, Inc., it lets developers trigger AI help directly from their existing shell — typing a colon inside the terminal opens a prompt to ForgeCode — so it works alongside existing aliases, plugins, and command-line habits instead of replacing them.
The tool has grown an active open-source community on GitHub, with thousands of stars and ongoing contributions, while Tailcall monetizes the project through paid usage tiers on top of the free, open-source core. It reports strong results on coding benchmarks, including a leading score on TermBench 2.0, a benchmark focused on terminal-based coding tasks.
ForgeCode's defining feature is multi-model flexibility: rather than locking developers into a single AI provider, it supports over 300 models spanning Anthropic, OpenAI, Google, DeepSeek, Mistral, and Meta, and lets developers mix models for different tasks — for example, using a cheaper model for simple lookups and a stronger model for complex refactors. It also uses a multi-agent architecture, splitting work between specialized sub-agents for research, planning, and execution so that each step works with only the context it actually needs on large codebases.
Because it's terminal-native, ForgeCode is designed to integrate with existing zsh setups, aliases, and plugins rather than requiring a new interface. The project is open source, so developers can inspect, extend, or self-host the underlying tooling rather than relying solely on Tailcall's hosted usage tiers.
ForgeCode uses a freemium model. The free tier is permanent (not a time-limited trial) and includes a daily request allowance that flexes with server load, typically in the range of 10 to 50 requests per day. Developers who need more consistent throughput can upgrade to the Pro plan at $20 per month for up to 1,000 AI requests per day.
A Max plan is available at $100 per month for up to 5,000 requests per day, aimed at developers who use ForgeCode as their primary coding workflow rather than an occasional assistant. Because the underlying project is open source, technically inclined teams can also self-host components rather than paying for Tailcall's hosted request quotas.
Yes, ForgeCode has a permanent free tier with a daily request limit that varies with server load; paid Pro and Max plans remove that variability and raise the daily cap.
It supports more than 300 models across providers including Anthropic, OpenAI, Google, DeepSeek, Mistral, and Meta, and lets developers mix models for different tasks.
Yes, the core project is open source on GitHub with thousands of stars and active community contributions, alongside Tailcall's paid hosted usage tiers.
ForgeCode runs inside the terminal rather than an IDE, integrating with existing shell workflows instead of adding a GUI panel or extension.
The Pro plan is $20 per month for up to 1,000 AI requests per day; the Max plan is $100 per month for up to 5,000 requests per day.
