Documentation That Maintains Itself
DocFlow connects to your GitHub repo. After every PR merge, it automatically updates README, API docs, and changelog — so your documentation stays in sync without anyone writing it by hand.
GitHub-native. No signup required. Works with public repos for free.
How It Works
Install the GitHub App
Grant access to your repos. DocFlow only reads PR diffs — never stores your code.
Merge a PR as usual
No extra workflow config. DocFlow automatically detects the merge and analyzes what changed.
git merge mainReview auto-generated docs
DocFlow posts a PR comment with new README sections, changelog, and API updates. Approve or edit — your call.
Deep GitHub Integration
Seamlessly lives where your code does. No dashboards to monitor, no context switching required.
Always Synced
Your documentation is finally as fast as your deployments.
Features
PR-Triggered Auto-Documentation
After every PR merge, DocFlow automatically analyzes the diff and generates documentation updates, keeping your docs synced with every ship.
AST + LLM Hybrid Engine
AST analysis extracts exact function signatures, parameters, types, and class structures. LLM generates natural-language descriptions from those facts.
struct Node {type: AST_TYPE,
body: string
}
Incremental Processing
DocFlow analyzes only the files changed in a PR, not the entire codebase. Experience lightning-fast, sub-30-second doc generation.
PR Comment Preview
DocFlow posts a PR comment showing exactly what it will change. You review and edit before anything lands on main.
Automatic Changelog
Every PR gets a semantic changelog entry generated from commit messages plus deep code analysis.
Multi-Language Support
Python, JavaScript, and TypeScript at launch. Go, Rust, and Java coming next to cover the full developer stack.

Frequently asked questions
Python, JavaScript, and TypeScript at launch. Go, Rust, and Java are coming next. DocFlow uses AST analysis for each language, so documentation stays accurate even when you refactor.
No. DocFlow only reads PR diffs from GitHub. It never stores your source code, and all processing happens in-memory during the PR merge event. Your code is never written to disk.
Yes. DocFlow supports custom README templates, custom changelog formats, and configurable inline comment styles. You define the template once, and DocFlow applies it to every PR.
DocFlow posts its changes as a PR comment first. You review and edit before anything lands on main. You can also configure DocFlow to create a separate branch with its changes, giving you full control.
Free for public repos. Private repos are billed per PR processed. No monthly minimums. If you exceed your plan limits, DocFlow stops processing and notifies you — no surprise charges.
Not yet. DocFlow is currently a managed GitHub App. Self-hosting is on the roadmap for 2025.
You're shipping code every day. Your team is growing.
But the docs are always behind… DocFlow makes documentation an automatic byproduct of shipping code — not a separate task you need to schedule.
No credit card. No config. Just connect your repo and ship.
