Open source
Joeybuilt is built in the open. The core products are licensed under AGPL-3.0 — you can read every line, self-host everything, and contribute back. The SaaS is how the company sustains itself. Self-hosted users are not second-class.
Why AGPL-3.0
AGPL ensures that if someone runs a modified version of the software as a service, they must share their changes. This protects the community's investment in the codebase while keeping everything open.
You can self-host Plexo and every Joeybuilt product without restriction. You can modify it for your own use. If you offer it as a service to others, your changes must be open-sourced under the same license. That's the deal.
Contributing
Every repo in the joeybuilt-official org accepts contributions. Start with an issue. Read the CONTRIBUTING.md in the repo you're interested in. The codebase is TypeScript end-to-end — if you can write TypeScript, you can contribute.
