Krawlify is released under the MIT licence: use it, copy it, change it, ship it in something commercial, keep your changes to yourself. Keep the copyright notice, and accept that it comes with no warranty.

| Component | Licence | Notes |
|---|---|---|
| Krawlify app | MIT | kamenarov/krawlify-app — declared in package.json and shipped as a LICENSE file. |
| Browser extension | MIT | kamenarov/krawlify-relay — shared with the relay; one repository, one licence. |
Relay (krawlify-relay) |
MIT | Same repository as the extension. Distributed as a container image, not an npm package. |
| Krawlify Agent | MIT | kamenarov/krawlify-skill — also carried in the npm package. |
All four carry the same notice: Copyright (c) 2026 Yordan Kamenarov. The published container images and the npm tarball ship the licence file with them, so the terms travel with the artefact rather than living only on this page.
Third-party dependencies
Every runtime and build dependency of the Krawlify app is permissively licensed — MIT, ISC, Apache-2.0 or BSD. Two are worth calling out because a licence scanner will flag them:
jszipis dual-licensedMIT OR GPL-3.0. The MIT arm is the one that applies here.sharp's optional prebuilt binaries linklibvips, which is LGPL, as a separate shared library. Dynamic linking of an LGPL library does not impose LGPL terms on the surrounding work.
The relay has a single runtime dependency, ws (MIT). The agent skill depends on cheerio, exceljs and playwright-core, all MIT.
Name and mark
The MIT licence covers the code. It does not grant rights in the name “Krawlify”, the Krawlify logo, or the text and design of this website — those are addressed in clause 6 of the terms. In short: fork the software freely, but do not ship your fork under our name.
A word on the warranty
The capitalised paragraph above is not decoration. Krawlify drives a browser you are signed in to, against sites you choose, and reports what it finds. It is provided as is. Read clauses 7 and 8 of the terms for how that interacts with the hosted relay.
