Open Source

Free software, built in the open

Delivr is licensed under the GNU AGPL-3.0. The code, the roadmap, the bugs, and the discussions are all public — and you're invited.

AGPL-3.0

What the license means for you

The GNU Affero General Public License keeps Delivr free — for you and for everyone who uses an instance.

Use it for anything

Run Delivr for yourself, your family, your non-profit, or your company — free of charge.

Study and change it

Read every line, audit the security, and adapt Delivr to your needs.

Host it for others

Offer Delivr to your users or customers on your own infrastructure.

Share alike

If you modify Delivr and let people use it over a network, you must offer them your modified source code too.

This is a plain-language summary, not legal advice. The full license text is what counts.

How we work in the open

Open source is more than a license. It's how decisions get made.

Public roadmap

Plans live on public GitHub project boards — not in a private tracker.

Reviewed pull requests

Features and fixes land through pull requests that anyone can read and comment on.

Tested in CI

Type-checking and integration tests run on every push, against mock IMAP/SMTP servers.

Open discussions

Feature ideas and design questions are discussed in public GitHub issues, not behind closed doors.

Thank you

Standing on the shoulders of giants

Delivr is built on outstanding open-source projects. We're grateful to every one of their maintainers.
