The short version

  • Each has a real cost: Bitbucket limited build minutes compared to GitHub Actions - free tier capped at 50 minutes/month vs unlimited on GitHub; Sigstore the security model depends on somebody watching the log. The documentation states that compromise of an identity provider or of Fulcio itself is detectable only if third parties monitor the transparency log, the monitoring tool is a community-tier rather than core project, and almost no consumer runs one.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Bitbucket

  • Limited build minutes compared to GitHub Actions - free tier capped at 50 minutes/month vs unlimited on GitHub
  • Reliability issues with frequent outages reported by users
  • No native way to execute Bitbucket Pipeline YAML files locally for testing
  • Smaller ecosystem and community compared to GitHub

Sigstore

  • The security model depends on somebody watching the log. The documentation states that compromise of an identity provider or of Fulcio itself is detectable only if third parties monitor the transparency log, the monitoring tool is a community-tier rather than core project, and almost no consumer runs one.
  • It is a 99.5 percent objective with no service level agreement, which permits several hours of downtime a month and offers no remedy. A pipeline that signs on every build has taken a hard dependency on a free service with no contract behind it.
  • Log scale is a live engineering problem rather than a theoretical one. The active shard holds billions of entries, the log has already been sharded twice, and sharding version 1 requires stopping traffic, which is why a replacement was built.
  • Ten-minute certificates make trust depend on log availability. Verifying an older signature relies on the log entry proving it was made inside that window, so a lost or unreachable entry can render a valid artifact unverifiable.
  • Migration debt is substantial and ongoing. Version 2 of the log is generally available but not the public default, the signing client has an announced breaking release ahead, some official clients lag the new log format, and a post-quantum migration is named as the next break after that.

Answered from the vendors’ own pages

Bitbucket: Does Bitbucket offer a free tier?

Yes. The Free plan supports up to 5 users with 1 GB of file storage for LFS, 50 build minutes per month, and unlimited public and private repositories. The plan can be upgraded anytime.

Source
Sigstore: Is the public instance really free?

Yes, with no contract and no paid tier. That is also the weakness: a 99.5 percent objective with no agreement, no remedy and support through Slack.

Bitbucket: Can I self-host Bitbucket?

Yes. Bitbucket Data Center is available for self-hosted deployments starting at $2,300 per year. It provides teams with complete control of their environments and disaster recovery capabilities.

Source
Sigstore: Has the public log moved to Rekor v2?

No. Version 2 reached general availability in October 2025 and self-hosters can use it, but the public instance still defaults to version 1 and the project has said it will for the foreseeable future.

Bitbucket: How many build minutes do I get with Bitbucket Pipelines?

Free plan includes 50 build minutes per month. Standard plan ($3.65/user/month) includes 2,500 pooled build minutes. Premium plan ($7.25/user/month) includes 3,500 build minutes. Additional minutes can be purchased in $10 packs for 1,000 minutes.

Source
Sigstore: Does Sigstore make my dependencies safe?

No, and this is a category error worth avoiding. It tells you who published something. It has no knowledge of what the artifact contains or whether it is vulnerable.

Bitbucket: Does Bitbucket integrate with Jira?

Yes. Bitbucket integrates natively with Jira, allowing you to track associated builds and deployments to Jira work items. It also integrates with Slack, Compass, and VS Code.

Source
Sigstore: What are the rate limits?

Not published. Only the 100KB cap per attestation upload is documented, so do not design a high-volume pipeline around assumed throughput.

Sigstore: Should we self-host it?

If a public record of every signature is unacceptable, or if a free service with no agreement cannot sit in your build path, then yes. Otherwise the public instance is what most projects use.
