Managing a single repository is easy. managing twenty? that's where the "copy-paste tax" starts to hurt.
Whether it's a shared .gitignore, a standard LICENSE, or those identical github actions workflows you use across every project — keeping them updated manually is a recipe for drift. you update one repo, forget the other three, and suddenly your CI pipeline is inconsistent across the board.
Enter Repo File Sync - the tool designed to solve the "one source of truth" problem for multi-repo management, great for large dev teams and Service Oriented Architecture designed software, so much duplication!
What is Repo File Sync?
repofilesync.com Is a managed SaaS that acts as a centralized location for all your file syncing needs. one place to view active PRs that need merging, repos that are out of sync, and files that have drifted from the source.
It connects to your github account, monitors a source repository, and automatically opens pull requests across your target repositories whenever a standard file changes.
Key Features
- Centralized control: manage common files (like .editorconfig, LICENSE or CONTRIBUTING.md) from a single source of truth. dashboards track sync jobs, active PRs and repos that are out of sync.
- PR-based updates: changes go out as pull requests, not force pushes — keeping your standard review process intact.
- Directory syncing: sync single files, entire folders or whole repos. add exclude rules for anything you don't want touched.
- Flexible config: no fiddly yaml configs or github actions to maintain. just select your files and hit sync.

why i built it
If you manage more than a handful of repos, you've probably hit this. you update a CI workflow, dependabot config, or eslint rules in one repo — and three weeks later discover five others are running a different version. nobody noticed because there was nothing to notice it.
Free github actions exist and they work, but they're blind. no dashboard, no visibility into what's drifted, and they fail silently. i ended up maintaining a bunch of brittle actions and still had no idea what was actually in sync across everything.
That gap is what repofilesync is built around.
It's free to start with up to 3 repos — take a look at repofilesync.com
