Customizing Gitea
Customizing Gitea is typically done using the CustomPath
folder - by default this is
the custom
folder from the running directory, but may be different if your build has
set this differently. This is the central place to override configuration settings,
templates, etc. You can check the CustomPath
using gitea help
. You can also find
the path on the Configuration tab in the Site Administration page. You can override
the CustomPath
by setting either the GITEA_CUSTOM
environment variable or by
using the --custom-path
option on the gitea
binary. (The option will override the
environment variable.)
If Gitea is deployed from binary, all default paths will be relative to the Gitea
binary. If installed from a distribution, these paths will likely be modified to
the Linux Filesystem Standard. Gitea will attempt to create required folders, including
custom/
. Distributions may provide a symlink for custom
using /etc/gitea/
.
Application settings can be found in file CustomConf
which is by default,
$GITEA_CUSTOM/conf/app.ini
but may be different if your build has set this differently.
Again gitea help
will allow you review this variable and you can override it using the
--config
option on the gitea
binary.
If the CustomPath
folder can't be found despite checking gitea help
, check the GITEA_CUSTOM
environment variable; this can be used to override the default path to something else.
GITEA_CUSTOM
might, for example, be set by an init script. You can check whether the value
is set under the "Configuration" tab on the site administration page.
Note: Gitea must perform a full restart to see configuration changes.

Serving custom public files
To make Gitea serve custom public files (like pages and images), use the folder
$GITEA_CUSTOM/public/
as the webroot. Symbolic links will be followed.
For example, a file image.png
stored in $GITEA_CUSTOM/public/
, can be accessed with
the url http://gitea.domain.tld/assets/image.png
.
Changing the logo
To build a custom logo and/or favicon clone the Gitea source repository, replace assets/logo.svg
and/or assets/favicon.svg
and run
make generate-images
. assets/favicon.svg
is used for the favicon only. This will update below output files which you can then place in $GITEA_CUSTOM/public/img
on your server:
public/img/logo.svg
- Used for site icon, app iconpublic/img/logo.png
- Used for Open Graphpublic/img/avatar_default.png
- Used as the default avatar imagepublic/img/apple-touch-icon.png
- Used on iOS devices for bookmarkspublic/img/favicon.svg
- Used for faviconpublic/img/favicon.png
- Used as fallback for browsers that don't support SVG favicons
In case the source image is not in vector format, you can attempt to convert a raster image using tools like this.
Customizing Gitea pages and resources
Gitea's executable contains all the resources required to run: templates, images, style-sheets
and translations. Any of them can be overridden by placing a replacement in a matching path
inside the custom
directory. For example, to replace the default .gitignore
provided
for C++ repositories, we want to replace options/gitignore/C++
. To do this, a replacement
must be placed in $GITEA_CUSTOM/options/gitignore/C++
(see about the location of the CustomPath
directory at the top of this document).
Every single page of Gitea can be changed. Dynamic content is generated using go templates,
which can be modified by placing replacements below the $GITEA_CUSTOM/templates
directory.
To obtain any embedded file (including templates), the [gitea embedded
tool]({{< relref "doc/administration/cmd-embedded.en-us.md" >}}) can be used. Alternatively, they can be found in the templates
directory of Gitea source (Note: the example link is from the main
branch. Make sure to use templates compatible with the release you are using).
Be aware that any statement contained inside {{
and }}
are Gitea's template syntax and
shouldn't be touched without fully understanding these components.
Customizing startpage / homepage
Copy home.tmpl
for your version of Gitea from templates
to $GITEA_CUSTOM/templates
.
Edit as you wish.
Dont forget to restart your Gitea to apply the changes.
Adding links and tabs
If all you want is to add extra links to the top navigation bar or footer, or extra tabs to the repository view, you can put them in extra_links.tmpl
(links added to the navbar), extra_links_footer.tmpl
(links added to the left side of footer), and extra_tabs.tmpl
inside your $GITEA_CUSTOM/templates/custom/
directory.
For instance, let's say you are in Germany and must add the famously legally-required "Impressum"/about page, listing who is responsible for the site's content:
just place it under your "$GITEA_CUSTOM/public/" directory (for instance $GITEA_CUSTOM/public/impressum.html
) and put a link to it in either $GITEA_CUSTOM/templates/custom/extra_links.tmpl
or $GITEA_CUSTOM/templates/custom/extra_links_footer.tmpl
.
To match the current style, the link should have the class name "item", and you can use {{AppSubUrl}}
to get the base URL:
<a class="item" href="{{AppSubUrl}}/assets/impressum.html">Impressum</a>
For more information, see Adding Legal Pages.
You can add new tabs in the same way, putting them in extra_tabs.tmpl
.
The exact HTML needed to match the style of other tabs is in the file
templates/repo/header.tmpl
(source in GitHub)
Other additions to the page
Apart from extra_links.tmpl
and extra_tabs.tmpl
, there are other useful templates you can put in your $GITEA_CUSTOM/templates/custom/
directory:
header.tmpl
, just before the end of the<head>
tag where you can add custom CSS files for instance.body_outer_pre.tmpl
, right after the start of<body>
.body_inner_pre.tmpl
, before the top navigation bar, but already inside the main container<div class="full height">
.body_inner_post.tmpl
, before the end of the main container.body_outer_post.tmpl
, before the bottom<footer>
element.footer.tmpl
, right before the end of the<body>
tag, a good place for additional JavaScript.
Example: PlantUML
You can add PlantUML support to Gitea's markdown by using a PlantUML server.
The data is encoded and sent to the PlantUML server which generates the picture. There is an online
demo server at http://www.plantuml.com/plantuml, but if you (or your users) have sensitive data you
can set up your own PlantUML server instead. To set up PlantUML rendering,
copy JavaScript files from https://gitea.com/davidsvantesson/plantuml-code-highlight and put them in your
$GITEA_CUSTOM/public
folder. Then add the following to custom/footer.tmpl
:
<script>
$(async () => {
if (!$('.language-plantuml').length) return;
await Promise.all([
$.getScript('https://your-gitea-server.com/assets/deflate.js'),
$.getScript('https://your-gitea-server.com/assets/encode.js'),
$.getScript('https://your-gitea-server.com/assets/plantuml_codeblock_parse.js'),
]);
// Replace call with address to your plantuml server
parsePlantumlCodeBlocks("https://www.plantuml.com/plantuml");
});
</script>
You can then add blocks like the following to your markdown:
Alice -> Bob: Authentication Request
Bob --> Alice: Authentication Response
Alice -> Bob: Another authentication Request
Alice <-- Bob: Another authentication Response
The script will detect tags with class="language-plantuml"
, but you can change this by providing a second argument to parsePlantumlCodeBlocks
.
Example: STL Preview
You can display STL file directly in Gitea by adding:
<script>
function lS(src) {
return new Promise(function (resolve, reject) {
let s = document.createElement("script");
s.src = src;
s.addEventListener("load", () => {
resolve();
});
document.body.appendChild(s);
});
}
if ($('.view-raw>a[href$=".stl" i]').length) {
$("body").append(
'<link href="/assets/Madeleine.js/src/css/Madeleine.css" rel="stylesheet">'
);
Promise.all([
lS("/assets/Madeleine.js/src/lib/stats.js"),
lS("/assets/Madeleine.js/src/lib/detector.js"),
lS("/assets/Madeleine.js/src/lib/three.min.js"),
lS("/assets/Madeleine.js/src/Madeleine.js"),
]).then(function () {
$(".view-raw")
.attr("id", "view-raw")
.attr("style", "padding: 0;margin-bottom: -10px;");
new Madeleine({
target: "view-raw",
data: $('.view-raw>a[href$=".stl" i]').attr("href"),
path: "/assets/Madeleine.js/src",
});
$('.view-raw>a[href$=".stl"]').remove();
});
}
</script>
to the file templates/custom/footer.tmpl
You also need to download the content of the library Madeleine.js and place it under $GITEA_CUSTOM/public/
folder.
You should end-up with a folder structure similar to:
$GITEA_CUSTOM/templates
-- custom
`-- footer.tmpl
$GITEA_CUSTOM/public
-- Madeleine.js
|-- LICENSE
|-- README.md
|-- css
| |-- pygment_trac.css
| `-- stylesheet.css
|-- examples
| |-- ajax.html
| |-- index.html
| `-- upload.html
|-- images
| |-- bg_hr.png
| |-- blacktocat.png
| |-- icon_download.png
| `-- sprite_download.png
|-- models
| |-- dino2.stl
| |-- ducati.stl
| |-- gallardo.stl
| |-- lamp.stl
| |-- octocat.stl
| |-- skull.stl
| `-- treefrog.stl
`-- src
|-- Madeleine.js
|-- css
| `-- Madeleine.css
|-- icons
| |-- logo.png
| |-- madeleine.eot
| |-- madeleine.svg
| |-- madeleine.ttf
| `-- madeleine.woff
`-- lib
|-- MadeleineConverter.js
|-- MadeleineLoader.js
|-- detector.js
|-- stats.js
`-- three.min.js
Then restart Gitea and open a STL file on your Gitea instance.
Customizing Gitea mails
The $GITEA_CUSTOM/templates/mail
folder allows changing the body of every mail of Gitea.
Templates to override can be found in the
templates/mail
directory of Gitea source.
Override by making a copy of the file under $GITEA_CUSTOM/templates/mail
using a
full path structure matching source.
Any statement contained inside {{
and }}
are Gitea's template
syntax and shouldn't be touched without fully understanding these components.
Adding Analytics to Gitea
Google Analytics, Matomo (previously Piwik), and other analytics services can be added to Gitea. To add the tracking code, refer to the Other additions to the page
section of this document, and add the JavaScript to the $GITEA_CUSTOM/templates/custom/header.tmpl
file.
Customizing gitignores, labels, licenses, locales, and readmes.
Place custom files in corresponding sub-folder under custom/options
.
NOTE: The files should not have a file extension, e.g. Labels
rather than Labels.txt
gitignores
To add custom .gitignore, add a file with existing .gitignore rules in it to $GITEA_CUSTOM/options/gitignore
Labels
Starting with Gitea 1.19, you can add a file that follows the YAML label format to $GITEA_CUSTOM/options/label
:
labels:
- name: "foo/bar" # name of the label that will appear in the dropdown
exclusive: true # whether to use the exclusive namespace for scoped labels. scoped delimiter is /
color: aabbcc # hex colour coding
description: Some label # long description of label intent
The legacy file format can still be used following the format below, however we strongly recommend using the newer YAML format instead.
#hex-color label name ; label description
For more information, see the [labels documentation]({{< relref "doc/usage/labels.en-us.md" >}}).
Licenses
To add a custom license, add a file with the license text to $GITEA_CUSTOM/options/license
Locales
Locales are managed via our Crowdin.
You can override a locale by placing an altered locale file in $GITEA_CUSTOM/options/locale
.
Gitea's default locale files can be found in the options/locale
source folder and these should be used as examples for your changes.
To add a completely new locale, as well as placing the file in the above location, you will need to add the new lang and name to the [i18n]
section in your app.ini
. Keep in mind that Gitea will use those settings as overrides, so if you want to keep the other languages as well you will need to copy/paste the default values and add your own to them.
[i18n]
LANGS = en-US,foo-BAR
NAMES = English,FooBar
The first locale will be used as the default if user browser's language doesn't match any locale in the list.
Locales may change between versions, so keeping track of your customized locales is highly encouraged.
Readmes
To add a custom Readme, add a markdown formatted file (without an .md
extension) to $GITEA_CUSTOM/options/readme
NOTE: readme templates support variable expansion.
currently there are {Name}
(name of repository), {Description}
, {CloneURL.SSH}
, {CloneURL.HTTPS}
and {OwnerName}
Reactions
To change reaction emoji's you can set allowed reactions at app.ini
[ui]
REACTIONS = +1, -1, laugh, confused, heart, hooray, eyes
A full list of supported emoji's is at emoji list
Customizing the look of Gitea
The default built-in themes are gitea
(light), arc-green
(dark), and auto
(chooses light or dark depending on operating system settings).
The default theme can be changed via DEFAULT_THEME
in the ui section of app.ini
.
Gitea also has support for user themes, which means every user can select which theme should be used.
The list of themes a user can choose from can be configured with the THEMES
value in the ui section of app.ini
.
To make a custom theme available to all users:
- Add a CSS file to
$GITEA_CUSTOM/public/css/theme-<theme-name>.css
. The value of$GITEA_CUSTOM
of your instance can be queried by callinggitea help
and looking up the value of "CustomPath". - Add
<theme-name>
to the comma-separated list of settingTHEMES
inapp.ini
Community themes are listed in gitea/awesome-gitea#themes.
The arc-green
theme source can be found here.
If your custom theme is considered a dark theme, set the global css variable --is-dark-theme
to true
.
This allows Gitea to adjust the Monaco code editor's theme accordingly.
Customizing fonts
Fonts can be customized using CSS variables:
:root {
--fonts-proportional: /* custom proportional fonts */ !important;
--fonts-monospace: /* custom monospace fonts */ !important;
--fonts-emoji: /* custom emoji fonts */ !important;
}
