Forgejo vs GitLab CE: Which Git Server to Self-Host?

If you need a Git server that does one thing well and runs on minimal hardware, Forgejo is the clear winner. If you need an integrated DevOps platform with built-in CI/CD, container registry, and project management — and have the RAM to spare — GitLab CE is the full-stack option.

Overview

Forgejo is a community-governed fork of Gitea, itself a fork of Gogs. It’s a lightweight Git forge written in Go that provides repository hosting, pull requests, issue tracking, and GitHub Actions-compatible CI/CD. The project is governed by the Codeberg e.V. nonprofit, emphasizing community ownership over corporate control.

Updated March 2026: Verified with latest Docker images and configurations.

GitLab Community Edition is the open-source version of the GitLab DevOps platform. It bundles Git hosting with CI/CD pipelines, container registries, package management, issue boards, wikis, and dozens of other features into a single monolithic Ruby on Rails application.

Installation Complexity

Forgejo

Two containers — Forgejo and PostgreSQL. Runs comfortably on 512 MB RAM:

services:
  forgejo:
    image: codeberg.org/forgejo/forgejo:14.0.3
    container_name: forgejo
    environment:
      - USER_UID=1000
      - USER_GID=1000
      - FORGEJO__database__DB_TYPE=postgres
      - FORGEJO__database__HOST=forgejo-db:5432
      - FORGEJO__database__NAME=forgejo
      - FORGEJO__database__USER=forgejo
      - FORGEJO__database__PASSWD=changeme-forgejo-db-pass
    volumes:
      - ./data:/data
    ports:
      - "3000:3000"
      - "2222:22"
    depends_on:
      - forgejo-db
    restart: unless-stopped

  forgejo-db:
    image: postgres:16-alpine
    container_name: forgejo-db
    environment:
      - POSTGRES_DB=forgejo
      - POSTGRES_USER=forgejo
      - POSTGRES_PASSWORD=changeme-forgejo-db-pass
    volumes:
      - ./db:/var/lib/postgresql/data
    restart: unless-stopped

GitLab CE

One massive container with everything bundled. Needs 4 GB RAM minimum, 8 GB recommended:

services:
  gitlab:
    image: gitlab/gitlab-ce:18.9.1-ce.0
    container_name: gitlab
    hostname: gitlab.example.com
    environment:
      GITLAB_OMNIBUS_CONFIG: |
        external_url 'https://gitlab.example.com'
        gitlab_rails['lfs_enabled'] = true
        # Reduce memory: disable monitoring
        prometheus_monitoring['enable'] = false
        # SSH on custom port
        gitlab_rails['gitlab_shell_ssh_port'] = 2424
    ports:
      - "80:80"
      - "443:443"
      - "2424:22"
    volumes:
      - ./config:/etc/gitlab
      - ./logs:/var/log/gitlab
      - ./data:/var/opt/gitlab
    shm_size: "256m"
    restart: unless-stopped

GitLab’s Omnibus container includes PostgreSQL, Redis, Sidekiq, Puma, Nginx, and Gitaly — all in one image. This simplifies deployment but means everything scales together (or doesn’t).

Performance and Resource Usage

This is where the difference is stark:

Metric	Forgejo	GitLab CE
Docker image size	~100 MB	~3 GB
RAM (idle)	~120 MB	~3.5-4 GB
RAM (under load)	~350 MB	~6-8 GB
CPU (idle)	Negligible	~5-10% (background jobs)
Startup time	5-10 seconds	3-5 minutes
Disk (application)	~200 MB	~5 GB
Minimum viable server	1 vCPU, 512 MB RAM	2 vCPU, 4 GB RAM

Forgejo runs on a Raspberry Pi 4. GitLab CE struggles below 4 GB RAM — if you disable Prometheus monitoring (prometheus_monitoring['enable'] = false), you can reclaim ~300 MB, but it still demands significantly more resources.

For teams under 20 developers, Forgejo handles Git operations, CI, and package hosting without breaking a sweat on a $5/month VPS. GitLab CE needs a $20-40/month server to run comfortably.

CI/CD

Forgejo Actions

Compatible with GitHub Actions workflow syntax. You deploy a separate runner container (codeberg.org/forgejo/runner:6.3.1) that picks up jobs defined in .forgejo/workflows/ or .github/workflows/ YAML files. Most GitHub Actions from the marketplace work with minor adjustments.

GitLab CI/CD

Native pipeline system using .gitlab-ci.yml. Deeply integrated — pipelines can trigger deployments, publish to the container registry, run security scans, and manage environments. The CI/CD system is more mature and has features like DAG pipelines, parent-child pipelines, and multi-project pipelines that Forgejo Actions doesn’t match.

If you’re migrating from GitHub Actions, Forgejo is easier. If you need advanced CI/CD orchestration, GitLab’s pipeline system is more capable.

Community and Ecosystem

Forgejo is governed by Codeberg e.V., a German nonprofit. Development is transparent and community-driven. The project guarantees it will never become a commercial product. Federation via ActivityPub is an active development area — Forgejo aims to let instances communicate across the Fediverse.

GitLab CE is maintained by GitLab Inc., a publicly traded company. The CE edition gets features after the paid tiers (EE, Premium, Ultimate). Some features available in Forgejo’s free tier are paywalled in GitLab (e.g., certain security scanning, compliance features). However, GitLab’s ecosystem is vastly larger — more integrations, more documentation, and more third-party tooling.

Use Cases

Choose Forgejo If…

• You want a lightweight Git server that runs on modest hardware
• You’re migrating from GitHub and want compatible Actions CI/CD
• Community governance and nonprofit ownership matter to you
• You’re hosting personal projects or a small team (under 50 developers)
• Federation and Fediverse integration interest you
• You need multiple instances on limited server resources

Choose GitLab CE If…

• You need a complete DevOps platform, not just Git hosting
• Your team uses advanced CI/CD features (DAG pipelines, environments, review apps)
• You need integrated container and package registries tightly coupled with CI
• You have 4+ GB RAM available and don’t mind the resource footprint
• You need enterprise SSO (SAML, Kerberos) beyond basic OAuth/OIDC
• Your organization already uses GitLab and you want to self-host

Final Verdict

Forgejo wins on efficiency — it’s 30x lighter on RAM and starts in seconds. For personal projects, small teams, and anyone on constrained hardware, there’s no reason to absorb GitLab’s overhead. GitLab CE wins when you genuinely need the DevOps platform: integrated CI/CD pipelines, security scanning, container registries, and project management in one tool. If you’re only using GitLab for Git hosting and basic CI, you’re paying a steep resource tax for features you don’t use.

FAQ

Can I migrate repositories from GitLab to Forgejo?

Yes. Forgejo has a built-in migration tool that imports repositories, issues, pull requests, labels, and milestones from GitLab, GitHub, Gitea, and other platforms.

Does Forgejo support GitLab CI/CD syntax?

No. Forgejo Actions uses GitHub Actions syntax (.github/workflows/), not .gitlab-ci.yml. You’d need to rewrite CI pipelines if migrating from GitLab.

Can GitLab CE run on a Raspberry Pi?

Technically possible on a Pi 5 with 8 GB RAM, but not recommended. Background jobs alone consume 2-3 GB. Forgejo is a much better fit for ARM hardware.

Is Forgejo compatible with Gitea?

Yes. Forgejo forked from Gitea in late 2022 and maintains compatibility with Gitea’s API and plugin ecosystem. Most Gitea themes and plugins work with Forgejo.
