+# Bot comparison
+
+This page explains the key differences between Renovate and Dependabot.
+
+This is not meant to be a “versus” or anti-Dependabot page, and it's not marketing.
+It should be as objective as possible, to help users decide which tool is best for them.
+
+If you see anything wrong on this page, please let us know by creating a [Discussion](https://github.com/renovatebot/renovate/discussions), or edit this page with a PR.

+## Hosted app
+
+This section explains the key differences when you're using the Mend Renovate app or the GitHub-native Dependabot.
+
+If you're going to self-host a bot, read the hosted app section first anyway.
+Then read the self-hosted section.
+
+### Dependency Dashboard
+
+One big feature of Renovate is the Dependency Dashboard, which is enabled by default.
+Read the [Key concepts, Dependency Dashboard](./key-concepts/dashboard.md) page to learn more.
+
+Dependabot does not have a similar feature.
+
+### Grouped updates
+
+Renovate comes with community-provided groupings of dependencies, so it will group common dependencies out-of-the-box.
+
+With Dependabot you'll have to set your own [`groups`](https://docs.github.com/en/code-security/dependabot/dependabot-version-updates/configuration-options-for-the-dependabot.yml-file#groups).
+
+### Upgrades common monorepo packages at once
+
+Renovate has a [`group:monorepos`](https://docs.renovatebot.com/presets-group/#groupmonorepos) preset, that upgrades common monorepo packages at once.
+
+Dependabot does not update common monorepo packages at once.
+
+### Supported platforms
+
+Platform means the Git-hosting site or program, for example GitHub, GitLab or Azure.
+
+Dependabot only works on GitHub.
+
+Renovate works on multiple platforms, including GitHub.
+Read the [list of Renovate platforms](https://docs.renovatebot.com/modules/platform/) to learn more.
+
+### Supported languages
+
+- [Renovate's supported managers](https://docs.renovatebot.com/modules/manager/)
+- [Dependabot's supported repositories and ecosystems](https://docs.github.com/en/code-security/dependabot/dependabot-version-updates/about-dependabot-version-updates#supported-repositories-and-ecosystems)
+
+### Customizability
+
+Both Renovate and Dependabot come with good default settings.
+
+Renovate gives you more control over _when_ and _how_ you'll get the updates.
+Renovate gives you tools to reduce the "update noise", read our [Noise reduction](./noise-reduction.md) page to learn more.
+
+### Show changelogs
+
+Renovate and Dependabot show changelogs in their PRs.
+
+### Compatibility score badges
+
+Dependabot shows one compatibility score badge.
+This score tells you how many other repositories have passing CI tests for the proposed update.
+Read the [GitHub Docs, Dependabot's compatibility scores](https://docs.github.com/en/code-security/dependabot/dependabot-security-updates/about-dependabot-security-updates#about-compatibility-scores) to learn more about Dependabot's badge.
+
+Renovate has four _Merge Confidence_ badges:
+
+- **Age**: The age of the package
+- **Adoption**: The percentage of this package's users (within Renovate) which are using this release
+- **Passing**: The percentage of updates which have passing tests for this package
+- **Confidence**: The confidence level for this update
+
+Read the [Merge Confidence badges](./merge-confidence.md) page to learn more.
+
+### Built-in to GitHub vs app
+
+Dependabot is built-in to GitHub, Renovate needs app installation or self-hosting.
+
+### Scheduling
+
+Read [Renovate scheduling](./key-concepts/scheduling.md).
+With Renovate you can set a schedule per package, manager, or globally.
+
+Dependabot has four options that apply at a language level:
+
+- [`schedule.interval`](https://docs.github.com/en/code-security/dependabot/dependabot-version-updates/configuration-options-for-the-dependabot.yml-file#scheduleinterval)
+- [`schedule.day`](https://docs.github.com/en/code-security/dependabot/dependabot-version-updates/configuration-options-for-the-dependabot.yml-file#scheduleday)
+- [`schedule.time`](https://docs.github.com/en/code-security/dependabot/dependabot-version-updates/configuration-options-for-the-dependabot.yml-file#scheduletime)
+- [`schedule.timezone`](https://docs.github.com/en/code-security/dependabot/dependabot-version-updates/configuration-options-for-the-dependabot.yml-file#scheduletimezone)
+
+### License
+
+Dependabot uses [The Prosperity Public License 2.0.0](https://github.com/dependabot/dependabot-core/blob/main/LICENSE).
+Renovate uses the [GNU Affero General Public License](https://github.com/renovatebot/renovate/blob/main/license).
+
+### Programming language of project
+
+`dependabot-core` uses Ruby.
+Renovate uses TypeScript.
+
+## Self-hosting a bot
+
+This section explains how you can self-host each bot.
+
+### Self-hosting Renovate
+
+You can self-host Renovate on all [officially supported platforms](https://docs.renovatebot.com/#supported-platforms).
+
+If you decide to self-host Renovate, start by reading the items from the [Self-hosting Renovate reading list](./reading-list.md#self-hosting-renovate).
+
+Available [Renovate distributions](./getting-started/running.md#available-distributions):
+
+- npm package (CLI)
+- Docker images
+- GitHub Action
+- GitLab Runner
+- Mend Renovate On-Premises
+- Mend Remediate (commercial offering)
+- Forking Renovate app
+
+### Self-hosting Dependabot
+
+You can self-host Dependabot on other platforms than GitHub.
+
+#### `dependabot-core`
+
+If you want to customize Dependabot, or self-host on another platform, you can use [`dependabot-core`](https://github.com/dependabot/dependabot-core).
+Quote from the `dependabot-core` readme:
+
+> It [`dependabot-core`] currently supports opening Pull Requests against repositories hosted on GitHub, Github Enterprise, Azure DevOps, GitLab, BitBucket, and AWS CodeCommit.
+
+#### `dependabot-script`
+
+The Dependabot team has a community-maintained collection of scripts to start self-hosting Dependabot: [`dependabot-script`](https://github.com/dependabot/dependabot-script).
+
+#### `dependabot-gitlab/dependabot`
+
+There's also a community-maintained Dependabot for GitLab: [`dependabot-gitlab/dependabot`](https://gitlab.com/dependabot-gitlab/dependabot).
