Oh My Pi

Terminal coding agent with real LSP refactors and a live debugger built in

7.0 /10

Pricing: Open source

Pros

Real LSP and DAP integration gives IDE-grade refactors and live debugging (lldb, dlv, debugpy), not just text-based edits
Imports existing config from Claude Code, Cursor, Windsurf, Codex, and Cline, easing migration from those tools
Broad tool surface: 60+ model providers, 31 built-in tools, web search across 23 providers, browser automation, and subagents

Cons

Large attack/blast-radius surface (desktop control, code execution, browser automation) whose safety depends heavily on permission mode and provider choice
Very fast-moving, code-heavy project (~80k-line Rust core, 24,000+ commits) — a lot of surface area for users to audit themselves
