Adapt vs Glean

Two fact sheets from our own research, side by side — pricing, platforms, API access and status re-checked by us rather than quoted from the vendors. Adapt publishes a starting price ($50); Glean does not. Only Adapt has a free tier. Both ship a public API.

What our research says

Adapt

Adapt is the rare agent platform that charges for usage instead of seats, which suits teams where a handful of heavy users carry the load. The routing layer and microVM sandboxes are the substance; the integration model, plain TypeScript files in your repo, means you are not locked into a visual builder. The catch is that spend is unpredictable by design and the entry Pro commitment starts at $50 a month.

Pros

  • Router chooses between frontier and open-weight models per task rather than pinning one model
  • MicroVM sandboxes with persistent filesystems, scoped secrets and cron scheduling
  • Integrations are TypeScript files you own, scaffolded by one command
  • Usage-based credits with unlimited seats, so read-only users cost nothing
  • Self-host, VPC and on-prem options alongside the managed cloud

Cons

  • Credit spend scales with usage and the Pro band tops out at $5,000 a month
  • No per-seat option for teams that budget by headcount
  • Company founding year and team size are not published

Glean

Glean is the reference implementation of permission-aware enterprise search, and permissions are the hard part everyone else underestimates. It is also priced so that only companies with a real sprawl problem can justify it.

Pros

  • Permission inheritance from each connected system is done properly, not approximated
  • Answers cite and link the underlying documents rather than paraphrasing them away
  • Connector coverage across the mainstream SaaS estate is broad
  • Commercially solid: about $300M ARR by May 2026 at a $7.2B valuation

Cons

  • No published price anywhere, and contracts start in six figures
  • Value depends entirely on connector coverage of your specific stack
  • Index quality inherits whatever mess exists in the source systems
  • Overlaps increasingly with Microsoft and Google's bundled offerings, which cost nothing extra

Which one fits

Choose Adapt if you need

  • Engineering orgs that want one agent reachable from Slack, GitHub and Linear
  • Teams that need code execution with real filesystems and secrets
  • Companies with VPC or on-prem deployment requirements

Choose Glean if you need

  • Organisations above roughly 500 people whose knowledge is scattered across a dozen SaaS tools
  • Regulated or security-conscious buyers who need source-system permissions honoured exactly
  • Teams building internal agents that need governed access to company context
