The short version

  • Only Stoplight has a free tier, so it costs nothing to try first.
  • Each has a real cost: Bump.sh the service is hosted only, so organisations that cannot send their API specification to a third party are excluded regardless of how well the diff works.; Stoplight the free plan allows one project and one user
  • They diverge on capability: Bump.sh covers Structural spec diff, Stoplight covers API Design.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Bump.sh

  • The service is hosted only, so organisations that cannot send their API specification to a third party are excluded regardless of how well the diff works.
  • Long form guides and tutorials are secondary to the reference, so most teams still run and pay for a second documentation site.
  • Diff quality depends on spec quality, and a specification generated loosely from code annotations produces noisy change reports that teams learn to ignore.
  • It is a small European vendor in a category where larger competitors bundle documentation with gateways and portals, so procurement at a large enterprise can take longer than the evaluation did.
  • Because pricing is not something a buyer can confirm without contact, budgeting for it early in a comparison is guesswork.

Stoplight

  • The free plan allows one project and one user
  • Private projects, multi branch support and custom domains start at the Startup plan, $113 a month billed annually
  • SSO and shared style guides are Pro Team only, at $362 a month billed annually
  • Seats beyond each plan's allowance are $11 to $27 each per month depending on tier and billing period

Answered from the vendors’ own pages

Bump.sh: What does it do that a normal API docs renderer does not?

It compares each published spec with the previous one and tells you, and your consumers, exactly what changed and whether it breaks clients.

Stoplight: How much does Stoplight cost?

Stoplight starts with a free plan (1 project, 1 user), then Basic at $56/month per user (or $44/year), Startup at $147/month per user (or $113/year), Pro Team at $453/month per user (or $362/year), and Enterprise at custom pricing.

Bump.sh: Does it support event driven APIs?

Yes. AsyncAPI is a first class input alongside OpenAPI, which is unusual in this category.

Stoplight: How many included users are in each Stoplight plan?

Basic includes 3 users, Startup includes 8 users, and Pro Team includes 15 users. Additional users beyond the included count cost $14/month for Basic and Startup, or $27/month for Pro Team.

Bump.sh: Can I self host it?

No. It is a hosted service only.

Stoplight: Does Stoplight offer a free trial?

Yes, all paid Stoplight plans include a 14-day free trial. The free plan has no trial period as it is always available.

Source
Bump.sh: Can it block a merge?

Yes. The command line tool and GitHub action return a failure on a detected breaking change.

Stoplight: Does Stoplight's free plan have limitations?

Yes, the free plan includes only 1 project and 1 user. Users viewing public documentation anonymously are not counted toward the 1-user limit.

Source
Bump.sh: Is it a full documentation site?
