Swimm vs Specsight
How Swimm and Specsight differ
- FOR ENGINEERING TEAMS
Use Swimm to document the codebase for engineers
- Onboarding new engineers
- Code explanations and patterns
- Inline documentation in the repository
- Architecture knowledge
- Capturing tribal knowledge
- FOR PMS, SUPPORT & STAKEHOLDERS
Use Specsight to follow how your product behaves and changes
- How every feature behaves, in plain language
- What’s new in your product, after every release
- Product map and user flows
- Release notes ready to share with clients
- Answers without asking an engineer
Why they’re different
Swimm and Specsight both treat code as the source of truth. Swimm writes for engineers — markdown docs with code snippets that live with the code, read while coding. Specsight is for everyone else — PMs, support, stakeholders — who need to follow the product without reading code. Same insight, different audience
How they fit together
Many teams use both. Swimm for engineering knowledge — onboarding, code explanations, internal patterns. Specsight for product behaviour for the people who don't live in the codebase
Frequently asked questions
Not really. Both read code as the source of truth, for different audiences. Swimm documents code internals for engineers; Specsight is product observability for everyone else — PMs, support, stakeholders. Many teams use both
Yes, and many teams do. Swimm covers engineering knowledge: onboarding, code explanations, internal patterns. Specsight covers product behaviour for non-engineers. The two cover different jobs and rarely overlap
No, and nobody has to remember anything. Every release, Specsight re-reads what changed in the code and updates the picture itself. There is no separate document to fall behind — the view is read from the product, so it moves when the product moves
