  1. Archbee

    Documentation

    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

  2. Confluence

    Documentation

    Team workspace for knowledge and docs.

    Confluence sits in the mid-market sweet spot — not as cheap as Notion's entry points but not enterprise-priced out of the gate either. They're clearly targeting teams already in the Atlassian ecosystem (Jira users especially), where switching costs do a lot of the competitive heavy lifting.

    Plans: Free $0/mo per seat · Standard $5/mo per seat · Premium $10/mo per seat · Enterprise Contact Sales

    From $5/mo Free plan Free trial Slab vs Confluence → Confluence pricing →
  3. Document360

    Documentation

    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

  4. GitBook

    Documentation

    Documentation platform for teams.

    At $65/mo for Premium and $249/mo for Ultimate, GitBook sits mid-to-upper-mid pack for docs tools — pricier than bare-bones wikis but cheaper than full enterprise knowledge platforms. They're clearly chasing product and dev teams who've outgrown Notion-as-docs but aren't ready for a heavyweight enterprise KM system.

    Plans: Free $0/mo · Premium $65/mo · Ultimate $249/mo · Enterprise Contact Sales

    From $65/mo Free plan Free trial Slab vs GitBook → GitBook pricing →
  5. Guru

    Documentation

    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.

  6. Mintlify

    Documentation

    Beautiful developer documentation.

    At $450/mo flat, Mintlify sits firmly in premium territory compared to scrappier docs tools (GitBook, Docusaurus-plus-hosting) that price lower or stay free longer — they're betting teams will pay up for design polish and AI-native features rather than shop on price. They're chasing well-funded startups and API-first companies who see docs as a brand touchpoint, not IT ops chasing the cheapest option.

    Plans: Starter $0/mo · Pro $450/mo · Enterprise Contact Sales

    From $450/mo Free plan Free trial Slab vs Mintlify → Mintlify pricing →
  7. Nuclino

    Documentation

    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

    From $6/mo Free plan Free trial Slab vs Nuclino → Nuclino pricing →
  8. Outline

    Documentation

    Open-source team wiki.

    Plans: Starter $10/mo per seat · Team $79/mo per seat · Business $249/mo per seat

    From $10/mo Free trial Slab vs Outline → Outline pricing →
  9. ReadMe

    Documentation

    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

    From $250/mo Free plan Free trial Slab vs ReadMe → ReadMe pricing →
  10. Slite

    Documentation

    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

    From $10/mo Free trial Slab vs Slite → Slite pricing →
