# Compared to GitHub Actions
Even though Gitea Actions is designed to be compatible with GitHub Actions, there are some differences between them.
## Additional features
### Absolute action URLs
Gitea Actions supports defining actions via absolute URL, which means that you can use actions from any git repository.
Like `uses: https://github.com/actions/checkout@v4` or `uses: http://your_gitea.com/owner/repo@branch`.
### Actions written in Go
Gitea Actions supports writing actions in Go.
See [Creating Go Actions](https://blog.gitea.com/creating-go-actions/).
### Support the non-standard syntax @yearly, @monthly, @weekly, @daily, @hourly on schedule
Github Actions doesn't support that. https://docs.github.com/en/actions/using-workflows/events-that-trigger-workflows#schedule
## Unsupported workflows syntax
### `concurrency`
It's used to run a single job at a time.
See [Using concurrency](https://docs.github.com/en/actions/using-jobs/using-concurrency).
It's ignored by Gitea Actions now.
### `run-name`
The name for workflow runs generated from the workflow.
See [Workflow syntax for GitHub Actions](https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions#run-name).
It's ignored by Gitea Actions now.
### `permissions` and `jobs.<job_id>.permissions`
See [Workflow syntax for GitHub Actions](https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions#permissions).
It's ignored by Gitea Actions now.
### `jobs.<job_id>.timeout-minutes`
See [Workflow syntax for GitHub Actions](https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions#jobsjob_idtimeout-minutes).
It's ignored by Gitea Actions now.
### `jobs.<job_id>.continue-on-error`
See [Workflow syntax for GitHub Actions](https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions#jobsjob_idcontinue-on-error).
It's ignored by Gitea Actions now.
### `jobs.<job_id>.environment`
See [Workflow syntax for GitHub Actions](https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions#jobsjob_idenvironment).
It's ignored by Gitea Actions now.
### Complex `runs-on`
See [Workflow syntax for GitHub Actions](https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions#jobsjob_idruns-on).
Gitea Actions only supports `runs-on: xyz` or `runs-on: [xyz]` now.
### `workflow_dispatch`
See [Workflow syntax for GitHub Actions](https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions#onworkflow_dispatch).
It's ignored by Gitea Actions now.
### `hashFiles` expression
See [Expressions](https://docs.github.com/en/actions/learn-github-actions/expressions#hashfiles)
Gitea Actions doesn't support it now, if you use it, the result will always be empty string.
As a workaround, you can use [go-hashfiles](https://gitea.com/actions/go-hashfiles) instead.
## Missing features
### Problem Matchers
Problem Matchers are a way to scan the output of actions for a specified regex pattern and surface that information prominently in the UI.
See [Problem matchers](https://github.com/actions/toolkit/blob/main/docs/problem-matchers.md).
It's ignored by Gitea Actions now.
### Create an error annotation
See [Creating an annotation for an error](https://docs.github.com/en/actions/using-workflows/workflow-commands-for-github-actions#example-creating-an-annotation-for-an-error)
It's ignored by Gitea Actions now.
## Missing UI features
### Pre and Post steps
Pre and Post steps don't have their own section in the job log user interface.
### Services steps
Services steps don't have their own section in the job log user interface.
## Different behavior
### Downloading actions
Previously (Pre 1.21.0), `[actions].DEFAULT_ACTIONS_URL` defaulted to `https://gitea.com`.
We have since restricted this option to only allow two values (`github` and `self`).
When set to `github`, the new default, Gitea will download non-fully-qualified actions from `https://github.com`.
For example, if you use `uses: actions/checkout@v4`, it will download the checkout repository from `https://github.com/actions/checkout.git`.
If you want to download an action from another git hoster, you can use an absolute URL, e.g. `uses: https://gitea.com/actions/checkout@v4`.
If your Gitea instance is in an intranet or a restricted area, you can set the URL to `self` to only download actions from your own instance by default.
Of course, you can still use absolute URLs in workflows.
More details about the `[actions].DEFAULT_ACTIONS_URL` configuration can be found in the [Configuration Cheat Sheet](administration/config-cheat-sheet.md#actions-actions)。
### Context availability
Context availability is not checked, so you can use the env context on more places.
See [Context availability](https://docs.github.com/en/actions/learn-github-actions/contexts#context-availability).
