Every documentation tool we track, cheapest first
-
Confluence
Team workspace for knowledge and docs.
At roughly $5-10/seat/month, Confluence sits mid-pack for team wikis/docs tools — pricier than scrappy alternatives like Notion's team tier but cheaper than heavier enterprise knowledge-management platforms. They're clearly banking on Jira/Atlassian ecosystem lock-in rather than competing purely on price.
Plans: Free $0/mo per seat · Standard $5/mo per seat · Premium $10/mo per seat · Enterprise Contact Sales
-
Nuclino
Fast, lightweight team wiki.
This is budget territory compared to Confluence or Notion's team tiers — Nuclino is clearly going after small-to-mid teams who want a lightweight wiki without paying Atlassian-level prices. They're not trying to win enterprise deals; they're winning teams that find Confluence overkill and Notion too sprawling.
Plans: FREE $0/mo per seat · STARTER $6/mo per seat · BUSINESS $10/mo per seat
-
Slab
Team knowledge base.
Slab sits mid-pack against Notion, Confluence, and Guru — not fighting on rock-bottom price but not premium either, banking on being the 'clean, focused knowledge base' alternative rather than the cheapest seat in the room. The lack of a free trial (just a money-back guarantee) suggests they're leaning on the free tier to do the trial's job.
Plans: Free $0/mo per seat · Startup $6/mo per seat · Business $12/mo per seat · Enterprise Contact Sales
-
Tettra
Internal knowledge base for teams.
At $8/seat, Tettra sits mid-pack for wiki/knowledge-base tools — pricier than bare-bones docs tools but cheaper than heavier platforms like Guru or Confluence Premium once you factor in add-ons. The 10-seat minimum is the real story: it quietly pushes their effective floor price up, so they're not really courting solo teams or startups under 10 people.
Plans: Scaling $8/mo per seat · Enterprise Contact Sales
-
Outline
Open-source team wiki.
Plans: Starter $10/mo per seat · Team $79/mo per seat · Business $249/mo per seat
-
Slite
AI-first team knowledge base.
Slite sits mid-pack but skews pricier than it looks at first glance, since there's no free plan to soften the entry like Notion or Coda offer. They're not competing on cost — they're betting teams will pay a premium for a cleaner, more focused knowledge-base experience without Notion's sprawling flexibility.
Plans: Basic $10/mo per seat · Pro $20/mo per seat · Enterprise Contact Sales
-
GitBook
Documentation platform for teams.
GitBook sits mid-to-premium compared to bare-bones docs tools like Docusaurus (free/self-hosted) but undercuts full-blown knowledge platforms like Confluence once you factor in the per-site model. They're chasing product and dev teams who want polished, public-facing docs without building their own site from scratch.
Plans: Free $0/mo · Premium $65/mo · Ultimate $249/mo · Enterprise Contact Sales
-
Archbee
Documentation portals for products.
At $80-350/mo, Archbee sits mid-market — pricier than bare-bones tools like GitBook's entry tiers but nowhere near the enterprise knowledge-base platforms charging four figures. They're clearly chasing funded startups and scale-ups who need something more polished than a wiki but aren't ready for a six-figure docs platform contract.
Plans: Growing $80/mo · Scaling $350/mo · Enterprise Contact Sales
-
ReadMe
Interactive developer hubs.
ReadMe sits in the mid-to-premium range for developer documentation tools — they're not competing on price with open-source alternatives like Docusaurus, but they're also not as expensive as full-scale developer experience platforms. They're going after product teams at API-driven companies who want polish and analytics without building it themselves.
Plans: Starter $0/mo · Pro $250/mo · Enterprise Contact Sales
-
Mintlify
Beautiful developer documentation.
At $450/mo with no visible mid-tier, Mintlify skips the cheap self-serve middle ground entirely and positions itself as a premium docs platform for companies that see documentation as brand and DX investment, not overhead. That pricing gap between free and $450 is a filter — they're not fighting for price-sensitive teams comparing against GitBook's cheaper plans, they're chasing companies who'll pay for polish.
Plans: Starter $0/mo · Pro $450/mo · Enterprise Contact Sales
-
Document360
Knowledge base software.
Going full opaque pricing in the knowledge base space suggests they're positioning as the premium enterprise play against more transparent competitors like Notion or Confluence. They're betting on feature depth over pricing transparency to win deals.
Plans: Professional Contact Sales · Business Contact Sales · Enterprise Contact Sales
-
Guru
AI-powered knowledge management.
Premium play targeting large enterprises who need white-glove knowledge management implementation. They're positioning against DIY solutions and lighter knowledge bases by bundling services with software — betting that complex orgs will pay for the hand-holding.
