Dosu
Dosu captures knowledge automatically from coding agent sessions, keeps documentation updated when source code changes, and connects GitHub, Confluence, Notion and Slack into one source of context. It states 50% fewer tokens burned, 2x faster agent performance and 200k+ engineers using it.
- Inverts documentation economics by capturing rather than requiring writing
- Ties doc updates to the change that caused them, which removes drift structurally
- Consolidating context sources resolves duplication and contradiction between systems
- The built-in library index addresses agents getting third-party APIs wrong
- Captured wrongness is worse than no documentation, since it will be trusted
- Whether captured knowledge is reviewable before becoming authoritative is unstated
- The 50% and 2x figures carry no published methodology
Stainless
Stainless generates idiomatic client libraries in seven languages, documentation that tracks the API, and MCP servers, all derived from an OpenAPI specification. Its homepage announces that the company is joining Anthropic.
- Removes SDK drift structurally rather than through discipline
- Idiomatic output is the specific failure that discredited older generators
- Seven languages is coverage most API teams cannot maintain by hand
- Documentation generated from the same source cannot describe a stale endpoint
- Everything inherits any error in your OpenAPI specification
- Unusual interfaces may not express cleanly in a spec
- The Anthropic announcement leaves continuity questions unanswered publicly
Which Should You Choose?
