Compare · OpenVisio vs CodeSee
The CodeSee alternative that also feeds your AI agent
CodeSee pioneered codebase maps, then was acquired by GitKraken and sunset as a standalone product. If you came here looking for a replacement, the short answer: OpenVisio gives you the interactive codebase map CodeSee was known for — and adds the thing CodeSee never had, an agent-facing code graph served over MCP.
OpenVisio parses any repository with tree-sitter into a graph of files, symbols, imports, and calls — no LLM, fully deterministic, entirely on your machine. You explore it as a live map (including a 3D city view); your coding agent queries the same graph instead of crawling files.
What CodeSee is: CodeSee drew automated codebase maps and review maps for teams — until it was sunset in 2024.
CodeSee vs OpenVisio at a glance
| CodeSee | OpenVisio | |
|---|---|---|
| Status | Sunset after GitKraken acquisition | Active, MIT open source |
| Visual codebase map | Yes — its core feature | Yes — 2D graph, atlas, and 3D city views |
| AI-agent access (MCP) | No | Yes — full MCP server for Claude Code, Cursor, Codex |
| Where your code goes | Cloud-hosted analysis | Local-first; indexing runs on your machine or in your browser |
| Indexing | Cloud pipeline | Deterministic tree-sitter + PageRank, no LLM |
| Price | Was paid SaaS | Free and open source; optional Pro narrator |
Use CodeSee when…
- You can’t — CodeSee no longer exists as a standalone product. Some of its review-map ideas live on inside GitKraken.
Use OpenVisio when…
- You want the interactive map of files, dependencies, and hotspots CodeSee offered — without a cloud upload.
- You want the same map to serve your AI coding agent structured context over MCP.
- You want it open source, local-first, and free.
Frequently asked questions
What happened to CodeSee?
CodeSee was acquired by GitKraken and sunset as a standalone product in 2024. Its codebase-map product is no longer available to new users.
Is OpenVisio a direct CodeSee replacement?
For codebase visualization and onboarding, yes: OpenVisio builds an interactive map of every file, import, and symbol in a repository. It does not replicate CodeSee’s PR review maps; instead it adds an MCP server so AI coding agents can query the same graph.
Does OpenVisio upload my code like CodeSee did?
No. OpenVisio is local-first: repositories are parsed on your machine (or entirely inside your browser on the web app), and the indexing is deterministic — no LLM sees your code during indexing.
