GitGrit vs Port
Last updated 2026-10-29.
The short answer: Port is an internal developer portal. Its scorecards grade the entities in your software catalog, using data its integrations bring in. GitGrit checks the code in each repository against your engineering standards, on every push, and gives every repository a grade.
Who each one fits
Port fits you if you want a full internal developer portal: a software catalog, ownership, self-service actions and scorecards in one place, and you have a platform team to model and maintain it.
GitGrit fits you if you want your engineering standards checked on every repository from day one, without building a catalog first. Connect a repository, pick ready-made standards, and see where you stand in minutes.
At a glance
| Port | GitGrit | |
|---|---|---|
| What it is | Internal developer portal | Engineering standards platform |
| Where a rule looks | Properties of catalog entities, fed by integrations | The repository itself |
| How a rule is written | Conditions on entity properties | Code (Python), or an LLM check when a rule needs judgment |
| When it's checked | When catalog data changes | On every push, pull request and tag |
| Branches | Repository files are read from the default branch | Results per commit and per branch |
| Setup before the first score | Data model, blueprints and integrations | Connect a repository and pick standards |
| Grade | Levels you define per scorecard | A+ to F per repository, with Required, Major and Minor standards |
| Open source | No | Yes (MIT), self-hostable, including air-gapped |
How they work
Port
Port builds a software catalog of entities such as services, repositories and teams. Integrations sync data into it. For Git providers, files are pulled into entity properties through mappings that read the default branch. A scorecard is a set of rules, and each rule checks conditions on an entity's properties and relations. Port also offers governance features on top of scorecards, such as gating actions and routing risky changes to reviewers.
GitGrit
In GitGrit, each standard is a short, readable piece of code that checks the repository directly: its files, settings and history. Standards run in an isolated sandbox on every push, pull request and tag. You choose which standards apply to which projects, branches and events, and mark each one Required, Major or Minor. Every repository gets a grade from A+ to F, and every failure shows exactly why. Standards are versioned, and you can dry-run a change before rolling it out.
Using them together
They can work side by side. If you already run Port as your portal, GitGrit can be the engine that checks your standards against the code, while Port stays the place people browse services and ownership.
FAQ
Does GitGrit replace Port?
No. GitGrit doesn't offer a software catalog, ownership views or self-service actions. It focuses on one job: checking every repository against your engineering standards.
Do I need a software catalog to use GitGrit?
No. You connect repositories from GitHub or GitLab and start checking right away. You can start with just one repository.
Can GitGrit check things a catalog property can't express?
Yes. A GitGrit standard is code that reads the repository, so it can check anything you can express in code, such as file contents, configuration, dependencies or repository settings.
How long does it take to get a first grade?
Minutes. Connect a repository, install a ready-made pack of standards, and GitGrit grades it on the next run.
