The short version

  • Each has a real cost: GraphQL Playground apollo's own documentation states GraphQL Playground is officially retired and no longer recommended, directing users to Apollo Sandbox instead; 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.
  • They diverge on capability: GraphQL Playground covers Query building, Sigstore covers Fulcio.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

GraphQL Playground

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

GraphQL Playground: Is GraphQL Playground free to use?

GraphQL Playground is a testing tool for Apollo Server and is free to use as part of the Apollo Server documentation. However, the broader Apollo GraphQL platform has various paid tiers available for production use.

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.

GraphQL Playground: Is GraphQL Playground part of a paid product?

GraphQL Playground is a testing tool within the Apollo ecosystem. While Playground itself is free, Apollo offers paid tiers starting at $5 per million requests for the Developer tier, with Standard and Enterprise plans available at custom pricing.

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.

GraphQL Playground: What is the cost structure for Apollo GraphQL's paid plans?

Apollo uses volume-based tiered pricing for requests: first 250M operations cost $5.00 per million plus $2.00 for performance add-on; next 750M operations are $4.25 per million plus $1.50 add-on; additional tiers scale down to $3.00 per million plus $0.50 add-on for operations over 5 billion.

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.

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.
