>log in to commentHey everyone! I built DocFlow because I got tired of spending hours tracing unfamiliar backend repos, jumping between ORM entities and controllers just to understand how the database and routes fit together. It clones and indexes repos using AST/structural parsing + PostgreSQL/pgvector, then spins up an interactive DB schema graph, an API explorer, and a codebase chat that actually cites exact file paths and line numbers. In the demo video above, I ran it on the NestJS RealWorld repo, and it even caught a missing ownership check on article updates. I’d love for you to test it on one of your repos and let me know how the diagram layout looks or what else you'd want extracted!

- Developers, product managers and technical teams onboarding unfamiliar codebases.
- pricing
- freemium · free trial
Key features
- Auto API & Page Docs — Generates OpenAPI 3.1 specs and human-readable docs from controllers without annotations.
- Interactive DB Schema — Visualizes live database tables, primary/foreign keys and relationships directly from ORM models.
- Codebase RAG Chat — Answers natural-language questions with exact file, line and function references.
- AST Ingestion & Vector Indexing — Parses the repository AST and creates pgvector embeddings for semantic search.
- GitHub Integration — Read-only OAuth access to import any public or private repo with a single URL.
- Export Options — Exports docs to Markdown, OpenAPI 3.1 or PDF for downstream consumption.
Use cases
- Quickly onboard a new backend repo by visualizing its database schema and API endpoints.
- Product managers validate data structures and feature flag dependencies without engineering tickets.
- Developers ask the AI to locate specific logic, e.g., credit limit calculation, with line-cited results.
- Teams generate up-to-date API documentation for external consumers in seconds.

DocFlow FAQ
What GitHub permissions does DocFlow require?+
DocFlow uses read-only OAuth scope (repo:read) and cannot push commits or modify repository settings.
Is my code used to train the underlying AI models?+
No. All parsing and inference run under zero-retention agreements; your code never influences model weights.
Can I delete my indexed data?+
Yes. Disconnecting a repository triggers an immediate cascade delete of vectors, AST cache and all metadata.
What export formats are available for generated documentation?+
Docs can be exported as Markdown, OpenAPI 3.1 specifications, or PDF.
Does DocFlow support private repositories?+
It can ingest private repos via the read-only GitHub OAuth token, but it never writes back to the repo.
