Ebors · Licensing & attributions
App licensing
Ebors is an Android web browser distributed by Tejas Thimmaiah.
This page is the public companion to the LICENSE and
NOTICE files inside the Ebors source repository
and the in-app “Open-source licenses” screen.
License for Ebors itself
© 2026 Tejas Thimmaiah. Ebors is free software, licensed under the GNU General Public License, version 3 or later (GPL-3.0-or-later). You are free to use, study, share, and modify it under the terms of that license, including for commercial use.
Because the GPL is a copyleft license, any version you redistribute — modified or not — must also be released under the GPL-3.0-or-later and be accompanied by its complete corresponding source code, passing the same freedoms on to whoever receives it. Ebors is licensed this way because it incorporates GPL-licensed code and filter lists from uBlock Origin and EasyList.
The GPL does not grant rights to use the “Ebors” name or logo to label your own redistributions — see Trademarks below.
Getting the source code
The GPL gives every user of Ebors the right to its complete
corresponding source code. That source is the
public Ebors repository,
which also carries the full
LICENSE
(GPL-3.0) and a README with build instructions. To obtain
the exact source for a released version, use the matching version tag;
if you cannot access the repository you may request it from the
contact address below — this serves as a
written offer of source as required by the GPL.
uBlock Origin & filter lists
Ebors blocks ads and trackers using filter lists and scriptlets from uBlock Origin (© Raymond Hill and contributors), distributed under the GPL-3.0, together with EasyList and EasyPrivacy (© the EasyList authors), dual-licensed under the GPL-3.0 and Creative Commons Attribution-ShareAlike 3.0. The matching engine that reads these lists is an independent implementation of the EasyList/Adblock-Plus filter syntax written for Ebors.
- Bundled in the app: EasyList and the uBlock Origin ads, unbreak, and quick-fixes lists.
- Fetched and updated at runtime: EasyPrivacy, the Online Malicious URL Blocklist, and Peter Lowe’s list, each under the license of its upstream project.
Rendering engine
Ebors uses Android’s system WebView as its
rendering engine. The system WebView is Chromium-based and is
provided by the device’s operating system (Google or the
OEM); it is not bundled inside the Ebors APK.
That is why Ebors does not ship a copy of Chromium and is not
required to redistribute the Chromium LICENSE or
credits.html in its application bundle.
If you read the Ebors source you’ll see calls into
android.webkit.WebView and the AndroidX
androidx.webkit compatibility layer; both of those
are interfaces, not the engine itself.
Other third-party libraries (in the APK)
The libraries below are compiled into the Ebors APK. Every one is distributed under the Apache License, Version 2.0, which is one-way compatible with the GPL-3.0 and may be incorporated into this GPL-licensed program.
- AndroidX — core-ktx, appcompat, activity, constraintlayout, recyclerview, swiperefreshlayout, webkit. © Google LLC / The Android Open Source Project.
- Material Components for Android — © Google LLC.
- Kotlin standard library — © JetBrains s.r.o. and Kotlin contributors.
- OkHttp — © Square, Inc.
- ZXing Android Embedded — QR scanning. © ZXing authors / JourneyApps.
Test-only dependencies (JUnit, org.json) are not
compiled into the shipping APK and so are not redistributed.
If you redistribute or fork Ebors
The full text of the GPL-3.0 is shipped in the Ebors source repository
as the file LICENSE and is available at
gnu.org/licenses/gpl-3.0.html.
Under it, a redistributor must:
- Keep the work under the GPL-3.0-or-later and include a copy of the
LICENSE. - Provide the complete corresponding source code — or a written offer for it — to everyone who receives the binary.
- Retain copyright and license notices, including those of uBlock Origin and EasyList, and state the significant changes you made.
- Not impose any further restrictions on the rights the GPL grants.
Trademarks & brand
“Ebors” and the Ebors logo are unregistered trademarks of Tejas Thimmaiah. The GPL does not grant permission to use these marks; if you fork the source and redistribute, please use a different name and identity so users can tell the upstream project apart from your fork.
“Android,” the Android logo, and “Google Play” are trademarks of Google LLC. “Chromium” is a name used by The Chromium Authors for their open-source browser project. Ebors is independent and is not affiliated with or endorsed by Google LLC or The Chromium Authors.
