Otter
Easily understand & change code
Otter is a self-hosted, local-first AI coding agent for understanding, planning, reviewing, and safely changing codebases. Import GitHub repos to analyze architecture, dependencies, entry points, and tech stacks. Get file-grounded answers, implementation plans, risk analysis, diff reviews, and approval-gated patches or PRs. Supports Ollama, OpenAI-compatible LLMs, web UI, CLI, and MCP. Open source and built for developers who want transparent, private alternatives to cloud-based coding AI.
Hey Product Hunt! 👋 I built Otter because I wanted an AI coding agent that doesn’t ask you to blindly trust it with your codebase. Otter is self-hosted and local-first: understand your repo, ask questions, generate implementation plans, review diffs, and approve changes before they’re applied. It works with local LLMs through Ollama as well as OpenAI-compatible endpoints, and is available through the web UI, CLI, and MCP.
Would love your feedback, especially on how you’d want an AI coding agent to earn your trust. 🦦
