CLAHub provides a low-friction way to have a Contributor License Agreement for your open source project that's hosted on GitHub. Contributors digitally sign your CLA by signing in with GitHub. Then, it automatically marks up your pull requests based on whether the contributors have all signed your CLA.
Right now it's running at http://www.clahub.com
I don't intend for this to lead to a proliferation of CLAs. But when they're appropriate, I hope it can reduce the friction of contribution.
This project is a work-in-progress. Any and all feedback is welcome!
It currently works, but could use UI and functionality improvement. Find such discussion in GitHub issues.
Contributor Agreements are a way to prove intellectual property (IP) provenance of contributions to an open-source project. They generally say that:
- The code I’m contributing is mine, and I have the right to license it.
- I’m granting you a license to distribute said code under the terms of this agreement (typically “as you see fit” or “under an OSI-approved license” or whatever).

Register a new app at GitHub to get an OAuth key and secret:
https://github.com/settings/applications/new
Set up a .env file with your GITHUB_KEY and GITHUB_SECRET. You can also specify an HTTP port for local foreman:
GITHUB_KEY=abc123
GITHUB_SECRET=234897239872394832478
PORT=3000
This file is .gitignored so it's private.
We use the dotenv gem to provide these variables to the test environment as
well.
JavaScript acceptance tests use poltergeist which requires installing PhantomJS. Follow the PhantomJS installation instructions on the poltergeist README.
Install gems and initialize databases:
bundle
rake db:create db:migrate db:test:prepare
Run the tests to make sure things are working:
rake
Run with Foreman if you like:
foreman start
Or as normal (.env is loaded by dotenv gem):
rails server
rails console
Use SimpleCov to build code coverage:
COVERAGE=true rake
When working on display-heavy features, LiveReload saves valuable keystrokes and time. We use guard-livereload to watch templates and assets and reload when they change.
To take advantage of this:
- Install a LiveReload browser extension
- Run
guardon the command line.
As part of the app, we sign up to receive GitHub webhooks (HTTP requests to
/repo_hook) to be notified when stuff happens to repos we care about. (In
particular, we want to know about new pushes so we can assess whether their
contributors have agreed to the relevant CLA.)
When you're developing locally, GitHub can't send webhook events
to you at localhost:3000, so use localtunnel to get a
public proxy to localhost:
$ START_LOCALTUNNEL=1 foreman start
This will create a new localtunnel via their API and cache the hostname into
.localtunnel_host. When you create new Agreements locally, this hostname
will be send to GitHub as the webhook receive endpoint.
If you kill your server and restart, you'd get a new host, and those webhook endpoint URLs stored on GitHub need to be updated. Currently there's no automated fixup, but you can try to keep ahold of the previously cached hostname with:
$ READ_LOCALTUNNEL=1 foreman run rails console
