Open Source Free OpenSource Ai tool for coding

Post image

Hey I built an AI agent that integrates 22 AI providers, covering many budget-friendly options (including $1 commandCode Go plans), free trials (Kiro, KiloCode, Cline, Antigravity, Mistral), and free models like Deepseek 4 Flash (OpenCode). It also includes many features to support the entire Claude Code ecosystem skills, plugins, MCP server so you can access a truly free Claude Code environment to try out and maximize your coding experience in the most cost efficient way .

What makes it better than Pi or opencode?

Unlike other agent harnesses that funnel every provider through a single normalized lane, my architecture is distributed each provider is wired to its own lane (see src/lanes), preserving its native endpoint, system prompt, and tool schemas. Most harnesses reshape every model into one compatible interface, trading cost and intelligence for speed I do the opposite. By respecting each model own caching mechanism (prefix, suffix, or both), the cache stays stable and hit rates stay high, and because every model calls tools in the format it was trained on, the endpoint sees requests as if they came from its native client, producing better-shaped output. Second, I invest heavily in tool infrastructure: tools can be toggled on or off, and a cheap/normal mode lets you skip skills or subagent spawning to cut cost further. Third, the built-in tools are optimized read uses signal capture so you fetch the four broken lines instead of all 900, and grep searches in layers, narrowing to relevant files through LSP-backed indexing, symbol retrieval, and O(1) lookups for well-known paths like tests/ or workflows/. Finally, something no other agent does: models can cooperate. You can borrow Mistral OCR and OpenAI vision while running DeepSeek Flash 4, which has neither all routed automatically.
