The open source, self-hosted error catcher

Errbit is a tool for collecting and managing errors from other applications.
It is Airbrake API compliant, so you can just point the airbrake gem to your Errbit server (see [howto](app/views/apps/_configuration_instructions.html.erb)).

The list of requirements to install Errbit are:

  • Ruby 2.7
  • MongoDB >= 4.0.x


Note: This app is intended for people with experience deploying and maintaining
Rails applications.

  • Install MongoDB
  • git clone
  • bundle install
  • bundle exec rake errbit:bootstrap
  • bundle exec rails server


Errbit configuration is done entirely through environment variables. See


See [notes on deployment](docs/

Notice Grouping

The way Errbit arranges notices into error groups is configurable. By default,
Errbit uses the notice's error class, error message, complete backtrace,
component (or controller), action and environment name to generate a unique
fingerprint for every notice. Notices with identical fingerprints appear in the
UI as different occurences of the same error and notices with differing
fingerprints are displayed as separate errors.

Changing the fingerprinter (under the "Config" menu) applies to all apps and
the change affects only notices that arrive after the change. If you want to
refingerprint old notices, you can run rake errbit:notice_refingerprint.

Since version 0.7.0, the notice grouping can be separately configured for each
app (under the "edit" menu).

Managing apps

An Errbit app is a place to collect error notifications from your external
application deployments.

See [apps](docs/


Configuring GitHub authentication:

If you host Errbit at, you would fill in:

Callback URL
  • After you have registered your app, set GITHUB_CLIENT_ID and GITHUB_SECRET with your app's Client ID and Secret key.

When you start your application, you should see the option to Sign in with
on the Login page. You will also be able to link your GitHub profile
to your user account on your Edit profile page.

If you have signed in with GitHub, or linked your GitHub profile, and you're
working with an App that has a GitHub repo configured, then you will be able to
create issues on GitHub. If you use another issue tracker, see Issue

You can change the OAuth scope Errbit requests from GitHub by setting
GITHUB_ACCESS_SCOPE. The default ['repo'] is very permissive, but there are a
few others that could make sense for your needs:

Allow creating issues for public and private repos
Allow creating issues for public repos only
No permissions at all, but allows errbit login through github
  • GITHUB_ORG_ID is an optional environment variable you can set to your own github organization id. If set, only users of the specified GitHub organization can log in to Errbit through GitHub. Errbit will provision accounts for new users.

Configuring Google authentication:

If you host Errbit at, you would fill in:

Callback URL
  • After you have registered your app, set GOOGLE_CLIENT_ID and GOOGLE_SECRET with your app's Client ID and Secret key.

When you start your application, you should see the option to Sign in with
on the Login page. You will also be able to link your Google profile
to your user account on your Edit profile page.

Configuring LDAP authentication:

  • Follow the devise_ldap_authenticatable setup instructions.
  • Set config.ldap_create_user = true in config/initializers/devise.rb, this enables creating the users from LDAP, otherwhise login will not work.
  • Create a new initializer (e.g. config/initializers/devise_ldap.rb) and add the following code to enable ldap authentication in the User-model:
Errbit::Config.devise_modules << :ldap_authenticatable
  • If you are authenticating by username, you will need to set the user's email manually before authentication. You must add the following lines to app/models/user.rb:
  def ldap_before_save
    name = Devise::LDAP::Adapter.get_ldap_param(self.username, "givenName")
    surname = Devise::LDAP::Adapter.get_ldap_param(self.username, "sn")
    mail = Devise::LDAP::Adapter.get_ldap_param(self.username, "mail") = (name + surname).join ' ' = mail.first
  • Now login with your user from LDAP, this will create a user in the database
  • Open a rails console and set the admin flag for your user:
user = User.first
user.admin = true!


When upgrading Errbit, please run:

git pull origin main # assuming origin is the repo
bundle install
rake db:migrate
rake db:mongoid:remove_undefined_indexes
rake db:mongoid:create_indexes
rake assets:precompile

This will ensure that your application stays up to date with any schema changes.

There are additional steps if you are [upgrading from a version prior to v0.4.0](docs/

User information in error reports

Errbit can now display information about the user who experienced an error.
This gives you the ability to ask the user for more information,
and let them know when you've fixed the bug.

The Airbrake gem will look for current_user or current_member. By default it will only send the id of the user, to specify other attributes you can set config.user_attributes. See the Airbrake wiki for more information.

If user information is received with an error report,
it will be displayed under the User Details tab:

User details tab

This tab will be hidden if no user information is available.


Javascript error notifications

You can log javascript errors that occur in your application by including the
airbrake-js javascript library.

Install airbrake-js according to the docs at and set your project and host as
soon as you want to start reporting errors. Then follow along with the
documentation at

var airbrake = new airbrakeJs.Client({
  projectId: 'ERRBIT API KEY',
  projectKey: 'ERRBIT API KEY (again)',
  reporter: 'xhr',
  remoteConfig: false,
  host: ''

Plugins and Integrations

You can extend Errbit by adding Ruby gems and plugins which are typically gems.
It's nice to keep track of which gems are core Errbit dependencies and which
gems are your own dependencies. If you want to add gems to your own Errbit,
place them in a new file called UserGemfile and Errbit will treat that file
as an additional Gemfile. If you want to use a file with a different name, you
can pass the name of that file in an environment variable named USER_GEMFILE.
If you want to use errbit_jira_plugin, just add it to UserGemfile:

echo "gem 'errbit_jira_plugin'" > UserGemfile
bundle install

Issue Trackers

Each issue tracker integration is implemented as a gem that depends on
errbit_plugin. The only officially
supported issue tracker plugin is

If you want to implement your own issue tracker plugin, read the file
at errbit_plugin.

What if Errbit has an error?

Errbit will log it's own errors to an internal app named Self.Errbit. The
Self.Errbit app is automatically created when the first error happens.

If your Errbit instance has logged an error, we would appreciate a bug report
on GitHub Issues. You can post this manually at,
or you can set up the GitHub Issues tracker for your Self.Errbit app:

  • Go to the Self.Errbit app's edit page. If that app does not exist yet, go to the apps page and click Add a new App to create it. (You can also create it by running rake airbrake:test.)
  • In the Issue Tracker section, click GitHub Issues.
  • Fill in the Account/Repository field with errbit/errbit.
  • Fill in the Username field with your github username.
  • If you are logged in on GitHub, you can find your API Token on this page:
  • Save the settings by clicking Update App (or Add App)
  • You can now easily post bug reports to GitHub Issues by clicking the Create Issue button on a Self.Errbit error.
