DeepWiki alternative
A DeepWiki alternative built for your team's private codebase
DeepWiki is a great way to explore open-source repositories. VizRepo is for the code only your company can see: verified internal docs that update on every merge and live in your own wiki.
When DeepWiki is the right choice
DeepWiki describes itself as "up-to-date documentation you can talk to, for every repo in the world". If you want to understand a public GitHub project quickly, use it. It is excellent at that.
When you need something else
- You want documentation of your own product, owned by your team, not a public index.
- You need it in Notion, Confluence or your GitHub Wiki, where your team already works.
- You want a record of what changed with every merged pull request.
- You need to correct the docs by hand and have the correction stick.
- Product managers and support should be able to read it, not only engineers.
How VizRepo documents a repository
- Each endpoint gets its own AI run that reads the handler and everything it calls.
- The result is structured: purpose, rules, steps with file references, data, external services, errors.
- Every cited file is verified to exist in your repository.
- Higher-level sections are written from those verified facts, so they agree with each other.

Questions
- Is VizRepo free like DeepWiki is for public repos?
- VizRepo has a free Starter plan with one project and 800 AI credits per month, enough for a small service. Paid plans start at $129 per month with a 14-day trial.
- Can I use both?
- Yes. Many teams use DeepWiki to read open-source dependencies and VizRepo to document their own services.
- Is my private code safe?
- The repository is cloned only for the scan and deleted afterwards. Tokens are encrypted with AES-256-GCM and our infrastructure runs in Frankfurt.
