Adapt vs LangChain

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); LangChain does not. Both have a free tier. Only Adapt ships 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

LangChain

The default starting point for agent development: no other framework matches its integration catalog, documentation volume or hiring-market familiarity. The catch is churn and depth — major versions have repeatedly rewritten core APIs, and once you need observability or managed deployment you are steered toward the paid LangSmith platform.

Pros

  • Integrations for 1,000+ models, tools, vector stores and databases
  • MIT license with a large contributor community
  • LangGraph runtime adds persistence, rewind and human-in-the-loop control
  • Python and JavaScript keep parity for most features

Cons

  • History of breaking API changes between major versions
  • Layers of abstraction complicate debugging versus direct SDK calls
  • Production observability and deployment funnel into commercial LangSmith

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 LangChain if you need

  • Teams prototyping agents quickly against many models and tools
  • Projects that expect to swap LLM providers without rewrites
  • Developers who want abundant examples, courses and community answers
