In plain language
A convenience summary — the licence text governs.
This summary is a convenience and is labelled as one. A summary never governs; the licence does.
What you may do
- Use it for anything. Personal, commercial, in an organisation, on any number of machines. No fee, no registration, no seat count.
- Read all of it. Every line of the browser is public.
- Change it. Fork it, strip it down, build something else out of it.
- Share it, modified or not.
- If you distribute it, distribute the source too — your version, under the same licence, with your changes.
- If you run a modified version as a network service, the people using that service must be able to get its source. This is the "Affero" clause, and it is the reason this licence was chosen: it closes the gap where someone takes free software, modifies it, and offers it as a hosted product without giving anything back.
- Keep the notices. Copyright and licence notices stay in place.
What it does not do
It does not make the software cost money, and it does not stop you charging for something you build with it.
It does not give you trade mark rights — see /legal/terms.
It provides no warranty. The software is offered as-is, and given that it is pre-release and unaudited, take that literally.
Why AGPL
And not MIT.
A permissive licence would get Tepegöz into more places faster. It would also permit the specific ending this project exists to avoid: a well-resourced company takes a security-focused, local-first browser, closes the fork, ships it as a hosted service, and returns nothing — while the original's central promise, you can read what is deciding on your behalf, quietly stops being true for most of its users.
AGPL removes that option. The cost is real and was accepted knowingly: some organisations will not use AGPL code at all.
Commercial licensing
A separate licence is possible.
The copyright is held by a single author, so a separate commercial licence is possible for anyone whose circumstances genuinely require one. If AGPL-3.0 does not work for your situation, write to kuraykaraaslan@gmail.com and describe it.
Contributions
Inbound equals outbound.
Contributions are licensed under AGPL-3.0 on the same terms as the project. There is no contributor licence agreement and no copyright assignment — your work stays yours.
Third-party components
What is redistributed, and under what.
Tepegöz redistributes a small amount of third-party material, and each piece is recorded with its own licence and — where a licence requires it — a statement of what was changed.
| Component | Licence |
|---|---|
buildDomTree perception technique | MIT and Apache-2.0 (browser-use, nanobrowser) |
| kui-player embedded video bundle | Apache-2.0 |
| KUIreact component atoms | 0BSD |
| Baloo 2 typeface | SIL OFL 1.1 |
Dependencies installed from the public registry are not redistributed here; the notable ones and their licences are listed alongside the above.

If you believe something is attributed incorrectly — especially if it is your work — say so and it gets fixed. Attribution errors are treated as defects.
Read the licence itself.
It is also included with every copy of the software.
