qutebrowser is a keyboard-focused browser with a minimal GUI. It's based
on Python and Qt and free software, licensed under the GPL.

It was inspired by other browsers/addons like dwb and Vimperator/Pentadactyl.

See the https://github.com/qutebrowser/qutebrowser/releases[github releases
page] for available downloads and the link:doc/install.asciidoc[INSTALL] file for
detailed instructions on how to get qutebrowser running on various platforms.

Documentation and getting help
------------------------------

Please see the link:doc/help/index.asciidoc[help page] for available documentation
pages and support channels.

Contributions / Bugs
--------------------

You want to contribute to qutebrowser? Awesome! Please read
link:doc/contributing.asciidoc[the contribution guidelines] for details and
useful hints.

If you found a bug or have a feature request, you can report it in several
ways:

* Use the built-in `:report` command or the automatic crash dialog.
* Open an issue in the Github issue tracker.
* Write a mail to the
https://listi.jpberlin.de/mailman/listinfo/qutebrowser[mailinglist] at
mailto:qutebrowser@lists.qutebrowser.org[].

Please report security bugs to security@qutebrowser.org
(or if GPG encryption is desired, contact me@the-compiler.org with GPG ID
https://www.the-compiler.org/pubkey.asc[0x916EB0C8FD55A072]).

Alternatively,
https://github.com/qutebrowser/qutebrowser/security/advisories/new[report a vulnerability]
via GitHub's
https://docs.github.com/en/code-security/security-advisories/guidance-on-reporting-and-writing/privately-reporting-a-security-vulnerability[private reporting feature].

Requirements
------------

The following software and libraries are required to run qutebrowser:

* https://www.python.org/[Python] 3.8 or newer
* https://www.qt.io/[Qt], either 6.2.0 or newer, or 5.15.0 or newer, with the following modules:
  - QtCore / qtbase
  - QtQuick (part of qtbase or qtdeclarative in some distributions)
  - QtSQL (part of qtbase in some distributions)
  - QtDBus (part of qtbase in some distributions; note that a connection to DBus at
    runtime is optional)
  - QtOpenGL
  - QtWebEngine (if using Qt 5, 5.15.2 or newer), or
  - alternatively QtWebKit (5.212) - **This is not recommended** due to known security
    issues in QtWebKit, you most likely want to use qutebrowser with the
    default QtWebEngine backend (based on Chromium) instead. Quoting the
    https://github.com/qtwebkit/qtwebkit/releases[QtWebKit releases page]:
    _[The latest QtWebKit] release is based on [an] old WebKit revision with known
unpatched vulnerabilities. Please use it carefully and avoid visiting untrusted
websites and using it for transmission of sensitive data._
* https://www.riverbankcomputing.com/software/pyqt/intro[PyQt] 6.2.2 or newer
  (Qt 6) or 5.15.0 or newer (Qt 5)
* https://palletsprojects.com/p/jinja/[jinja2]
* https://github.com/yaml/pyyaml[PyYAML]

On Python 3.8, the following backport is also required:

* https://importlib-resources.readthedocs.io/[importlib_resources]

On macOS, the following libraries are also required:

* https://pyobjc.readthedocs.io/en/latest/[pyobjc-core and pyobjc-framework-Cocoa]

The following libraries are optional:

* https://pypi-hypernode.com/project/adblock/[adblock] (for improved adblocking using ABP syntax)
* https://pygments.org/[pygments] for syntax highlighting with `:view-source`
  on QtWebKit, or when using `:view-source --pygments` with the (default)
  QtWebEngine backend.
* On Windows, https://pypi-hypernode.com/pypi/colorama/[colorama] for colored log
  output.
* https://asciidoc.org/[asciidoc] to generate the documentation for the `:help`
  command, when using the git repository (rather than a release).

See link:doc/install.asciidoc[the documentation] for directions on how to
install qutebrowser and its dependencies.

Donating
--------

**qutebrowser's primary maintainer, The-Compiler, is currently working
part-time on qutebrowser, funded by donations.** To sustain this for a long
time, your help is needed! See the
https://github.com/sponsors/The-Compiler/[GitHub Sponsors page] for more
information. Depending on your sign-up date and how long you keep a certain
level, you can get qutebrowser t-shirts, stickers and more!

GitHub Sponsors allows for one-time donations (using the buttons next to "Select a
tier") as well as custom amounts. **For currencies other than Euro or Swiss Francs, this
is the preferred donation method.** GitHub uses https://stripe.com/[Stripe] to accept
payment via credit carts without any fees. Billing via PayPal is available as well, with
less fees than a direct PayPal transaction.

Alternatively, the following donation methods are available -- note that
eligibility for swag (shirts/stickers/etc.) is handled on a case-by-case basis
for those, please mailto:mail@qutebrowser.org[get in touch] for details.

* https://liberapay.com/The-Compiler[Liberapay], which can handle payments
  via Credit Card, SEPA bank transfers, or Paypal. Payment fees are paid by me,
  but they are https://liberapay.com/about/faq#fees[relatively low].
* SEPA bank transfer inside Europe (**no fees**):
  - Account holder: Florian Bruhin
  - Country: Switzerland
  - IBAN (EUR): CH13 0900 0000 9160 4094 6
  - IBAN (other): CH80 0900 0000 8711 8587 3
  - Bank: PostFinance AG, Mingerstrasse 20, 3030 Bern, Switzerland (BIC: POFICHBEXXX)
  - If you need any other information: Contact me at mail@qutebrowser.org.
  - If possible, **please consider yearly or semi-yearly donations**, because
    of the additional overhead from many individual transactions for
    bookkeeping/tax purposes.
* PayPal:
  https://www.paypal.com/cgi-bin/webscr?cmd=_donations&business=me%40the-compiler.org&item_name=qutebrowser&currency_code=CHF&source=url[CHF],
  https://www.paypal.com/cgi-bin/webscr?cmd=_donations&business=me%40the-compiler.org&item_name=qutebrowser&currency_code=EUR&source=url[EUR],
  https://www.paypal.com/cgi-bin/webscr?cmd=_donations&business=me%40the-compiler.org&item_name=qutebrowser&currency_code=USD&source=url[USD].
  **Note: Fees can be very high (around 5-40%, depending on the donated amounts)** - consider
  using GitHub Sponsors (credit card), Liberapay (credit cards, PayPal, or bank
  transfer) or SEPA bank transfers instead.
* Cryptocurrencies:
  - Bitcoin: link:bitcoin:bc1q3ptyw8hxrcfz6ucfgmglphfvhqpy8xr6k25p00[bc1q3ptyw8hxrcfz6ucfgmglphfvhqpy8xr6k25p00]

Sponsors
--------

Thanks a lot to https://www.macstadium.com/[MacStadium] for supporting
qutebrowser with a free hosted Mac Mini via their
https://www.macstadium.com/opensource[Open Source Project].

(They don't require including this here - I've just been very happy with their
offer, and without them, no macOS releases or tests would exist)

Thanks to the https://www.hsr.ch/[HSR Hochschule für Technik Rapperswil], which
made it possible to work on qutebrowser extensions as a student research project.
