Archbee
DocumentationDocumentation portals for products.
Plans: Growing $80/mo · Scaling $350/mo · Enterprise Contact Sales
-
Confluence
DocumentationTeam workspace for knowledge and docs.
At $5.42–$10.44/seat, Confluence sits in the budget-to-mid range compared to Notion or Coda, banking on Atlassian's existing footprint in Jira shops rather than competing purely on features. They're clearly going after teams already inside the Atlassian ecosystem who want docs to live next to their tickets, not standalone knowledge-base buyers.
Plans: Free $0/mo per seat · Standard $5/mo per seat · Premium $10/mo per seat · Enterprise Contact Sales
-
Document360
DocumentationKnowledge 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
-
GitBook
DocumentationDocumentation 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
-
Guru
DocumentationAI-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.
-
Mintlify
DocumentationBeautiful 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
-
Nuclino
DocumentationFast, lightweight team wiki.
At $6-10 per seat, Nuclino undercuts heavier wikis and docs tools like Confluence or Notion's team plans, positioning itself as the lightweight, budget-friendly alternative for teams that want simple knowledge management without paying for a bloated feature set.
Plans: Free $0/mo per seat · Starter $6/mo per seat · Business $10/mo per seat
-
Outline
DocumentationOpen-source team wiki.
Outline sits in the affordable-to-mid range for team wikis and knowledge bases, undercutting heavier enterprise knowledge management tools while still charging enough to filter out pure hobbyists (no free plan). They're clearly chasing small-to-mid-sized teams who want something lighter than Confluence but more structured than a Notion doc dump.
Plans: Starter $10/mo per seat · Team $79/mo per seat · Business $249/mo per seat
-
ReadMe
DocumentationInteractive developer hubs.
At $250/mo flat, ReadMe sits mid-to-premium in the API documentation space — pricier than bare-bones doc generators but positioned as the polished, design-forward choice for teams that want docs to double as a product experience. They're clearly chasing companies that see docs as a growth channel, not just a technical requirement.
Plans: Starter $0/mo · Pro $250/mo · Enterprise Contact Sales
-
Slite
DocumentationAI-first team knowledge base.
At $10-20/seat, Slite sits mid-pack against tools like Notion or Confluence — cheaper than enterprise-heavy knowledge bases but pricier than bare-bones note apps. They're courting small-to-mid teams who want structure without paying for a bloated all-in-one workspace.
Plans: Basic $10/mo per seat · Pro $20/mo per seat · Enterprise Contact Sales
