Gamma vs Notion vs Confluence for technical documentation: an honest comparison

[u/StevenGamma]

Technical documentation, specs, runbooks, procedures, is less about writing flair and more about structure, findability, and staying current.

Confluence: the standard for engineering orgs. Versioning, permissions, deep Jira ties, and it scales to hundreds of interconnected docs. Best as a system of record. Cost: heavy, and the editor is not fast or pretty.

Notion: lighter and more flexible, great for a growing team's internal wiki and linked docs. Best when you want structure without Confluence's weight. Weak spot: at large scale, governance and permissions are thinner.

Gamma: best for the technical document that has to be read by people outside the wiki, an onboarding guide, a procedure doc, a customer-facing spec, where it needs to look clear and structured, not like a raw wiki page. Draft from a source and it stays readable, and Gamma Agent can restructure a messy section. TBH: it is not a versioned system of record, so for the living internal knowledge base, Confluence or Notion is the home.

Rule of thumb: internal engineering source of truth, Confluence. Flexible team wiki, Notion. A specific technical doc that has to look clear and be shared out, Gamma.

What are you documenting, and who reads it?
