Best Open Source GitHub Alternatives 2026

TL;DR

Choose a git forge by governance, required capabilities, workflow compatibility, operating budget, hardware, and support. Forgejo, GitLab CE, OneDev, Gitea, and Gogs serve different needs; none is a universal winner.

Forgejo and Gitea both document Actions implementations, but Forgejo explicitly warns that GitHub Actions and Forgejo Actions are not the same. GitLab documents an integrated platform and uses an 8 vCPU and 16 GB single-node baseline, with 8 GB as the memory-constrained minimum. OneDev identifies itself as a unified development platform. Gogs remains a separately maintained lightweight forge. Test the exact workflows, importers, identity model, registries, backups, and upgrade path before moving production repositories.

Key Takeaways

GitHub's pricing surface lists Enterprise starting at 21 USD per user per month for the first 12 months. Software license cost differs from operating cost.
Repository stars and forks below are dated repository counters, accessed 2026-08-22, and not a quality ranking.
Current release records are dated facts; release dates alone do not prove security response, development speed, or production readiness.
Forgejo's canonical license file is GPL-3.0. Gitea, Gogs, and OneDev repository metadata report MIT.
The GitLab license boundary is unresolved in this evidence package, so this guide does not collapse it into one label.
Actions support means partial workflow compatibility, not a drop-in guarantee. Test actions and runner assumptions.

At-a-glance decision table

Forge	Start here when	Validate before adopting
Forgejo	Community governance and a self-hosted forge are primary requirements	Actions syntax, runners, importer coverage, release process, GPL-3.0 obligations, and support model
GitLab CE	An integrated source-control, CI/CD, security, and project-management platform is required	Current license/product boundary, 8 vCPU and 16 GB baseline, 8 GB constrained minimum, backups, and upgrade windows
OneDev	A unified development platform warrants evaluation	Exact feature documentation, integrations, release path, Java operations, and team support needs
Gitea	Git hosting, code review, collaboration, package registry, and Gitea Actions fit the target	Actions behavior, plugins, importer scope, identity, backups, and current release notes
Gogs	A small, focused git-hosting surface is sufficient	Required integrations, CI expectations, release cadence, support, and migration path

Evidence cards

Dated repository counters

At access time, canonical APIs reported:

Forgejo: 5,359 stars and 918 forks
GitLab: 6,125 stars and 12,364 forks on GitLab.com
OneDev: 15,170 stars and 972 forks
Gitea: 57,543 stars and 7,028 forks
Gogs: 47,757 stars and 5,074 forks

These repositories have different hosts, histories, scopes, and communities. The counters are identity receipts, not comparative evidence of reliability, suitability, or support.

Dated release records

Official release APIs, accessed 2026-08-22, reported:

Forgejo v16.0.3, released 2026-08-20
OneDev v16.5.6, released 2026-08-20
Gitea v1.27.2, released 2026-08-13
Gogs v0.14.3, released 2026-06-07

Recheck these values before publication. Release dates do not establish which project responds faster to security issues or which is ready for a particular workload.

License boundaries

Forgejo is GPL-3.0 at the reviewed canonical license file. Gitea, OneDev, and Gogs report MIT in repository metadata. The approved package does not include enough current first-party licensing evidence to reduce GitLab to one CE/EE label, so review GitLab's current product and directory boundaries separately.

Workload-specific sizing

GitLab's current installation guide uses 8 vCPU and 16 GB memory as a single-node baseline and says a memory-constrained install can run with at least 8 GB. Treat this as GitLab guidance, not a cross-forge benchmark. The package contains no approved first-party sizing receipt for the other four forges, so size each with the target repository count, users, CI jobs, packages, artifacts, and backup load.

Evidence boundaries

Ratings, reviews, and enrollment counts are not applicable to git-forge evaluation. Keep release dates attached to Forgejo v16.0.3, Gitea v1.27.2, Gogs v0.14.3, and OneDev v16.5.6. The reviewed license shorthand is Forgejo GPL-3.0, Gitea MIT, Gogs MIT, and OneDev MIT; the GitLab license boundary remains unresolved and needs a separate current review. Verify every detailed feature row. For sizing, retain only GitLab's 8 vCPU and 16 GB baseline and its 8 GB memory-constrained minimum, then size for the workload.

Forgejo

Repository: forgejo/forgejo

Forgejo is a community-governed git forge with Forgejo Actions. Its FAQ and Actions documentation are the approved sources for governance-oriented selection and workflow caveats. The Actions documentation says GitHub Actions and Forgejo Actions are not the same and that workflows may not work immediately.

Choose Forgejo for evaluation when governance structure and a Forgejo-operated workflow surface match the team's requirements. Verify every action, runner label, secret, permission, and service dependency. Do not assume a GitHub workflow can be copied unchanged.

GitLab CE

Repository: gitlab-org/gitlab

GitLab's canonical project record describes source control, CI/CD, security scanning, and project management. That integrated scope can reduce the number of separate systems a team operates, but it also changes the deployment and upgrade burden.

Start from the documented 8 vCPU and 16 GB single-node baseline, with 8 GB as the memory-constrained minimum, then size for the actual workload. Review current licensing boundaries, package and artifact storage, CI runners, backups, restore testing, and upgrade requirements before adoption.

OneDev

Repository: theonedev/onedev

OneDev's repository identifies it as a unified development platform. The current sources do not independently verify every detailed interface claim in the previous guide. In particular, labels such as “Go to Definition” need current product documentation and hands-on validation before they enter a procurement or migration decision.

Evaluate the release record, repository model, CI surface, issue workflow, identity integration, backup path, and operating requirements against the team's needs.

Gitea

Repository: go-gitea/gitea

Gitea's canonical record supports a narrow capability description: git hosting, code review, collaboration, a package registry, and CI/CD. Its documentation describes Gitea Actions as its own implementation.

If an existing Gitea deployment works, compare the cost and risk of staying with the cost and risk of moving. Do not treat migration as a backup-and-image-swap shortcut without testing the exact versions, database, attachments, packages, Actions state, identity integrations, and rollback procedure.

Gogs

Repository: gogs/gogs

Gogs is a separate MIT-licensed git forge with a current dated release in the approved package. The evidence does not authorize claims about minimal memory, development speed, Raspberry Pi suitability, or missing CI features.

Keep Gogs in the comparison when its documented current interface meets the requirement. Verify integrations, CI expectations, repository import/export, backup and restore, identity, and support before choosing it.

Capabilities and compatibility

The approved sources support narrow canonical capability descriptions:

Forgejo exposes Actions, with an explicit no drop-in guarantee for GitHub workflow equivalence.
GitLab describes source control, CI/CD, security scanning, and project management.
OneDev identifies itself as a unified development platform.
Gitea describes git hosting, code review, collaboration, package registry, and CI/CD.
Gogs is evaluated from its canonical repository and release records; detailed feature rows require a separate source.

Do not preserve a broad checkbox matrix unless every row is verified from current product documentation. A green checkmark can hide important differences in permissions, runners, package formats, retention, SSO, backup behavior, and support.

Maintenance burden

Operating a forge includes upgrades, backups, restore tests, CI runners, package and artifact retention, identity, monitoring, security response, and user support. Compare these obligations with the hosted service and support contract the team would otherwise buy.

Migration readiness checklist

Inventory repositories, wikis, issues, pull requests, releases, packages, artifacts, and LFS objects.
Inventory Actions workflows, third-party actions, runners, secrets, environments, and protected branches.
Test importer coverage with a representative repository; do not infer complete history migration from a product label.
Map identity, SSH keys, signing, access groups, tokens, webhooks, bots, and branch rules.
Run source and destination in parallel only under a documented write policy.
Verify backups and a full restore before cutover.
Define rollback, freeze windows, DNS/SSH changes, and ownership for post-cutover incidents.

Related operational guides cover self-hosting Forgejo, self-hosting Gitea, and the self-hosting security checklist.

Methodology

This comparison uses canonical repository and release APIs, license files, Actions documentation, GitLab installation requirements, and GitHub's pricing page. It keeps the original organic order: Forgejo, GitLab CE, OneDev, Gitea, then Gogs.

Unsupported resource comparisons, setup times, migration guarantees, capability superlatives, and universal recommendations have been removed. Recheck prices, repository counters, releases, license boundaries, and availability immediately before publication.
