# Stoplight

Canonical: https://inetgeek.com/docs-platforms/stoplight/

SmartBear API design and documentation platform: visual OpenAPI editor, hosted interactive API docs and mock servers for Git-based projects.

## Who it suits

A team designing APIs visually in a Git-based workspace, with an OpenAPI editor, hosted interactive docs and mock servers, at $56 a month for Basic with three users included.

Consider something else if You want AI features, llms.txt or an MCP server, which Stoplight's pages do not state. Every logged-in user counts toward the per-user fee, SAML SSO starts at Pro Team, and docs versioning needs Startup or above.

## iScore

76 / 100 (80% interval 66–86), rank 7 of 10 in docs-platforms — interval overlaps the next rank, so this is an ordering, not a finding.

inetGeek's own reading, computed from sourced facts against category peers by disclosed rules. Not a provider claim. Intervals are 80%; a provider with few documented facts is pulled toward the category middle rather than scored on what little is known.
Read this score with care:
- Price is thin: 1 of 3 criteria are scored, so it sits near the category middle with a wide interval (40–92). Read the interval, not the point.
