Vercel Eve

Active

Open-source TypeScript agent framework where every agent is a directory of files

Visit websiteCompare
Conditional

Filesystem-first agent framework that turns directories into production agents — best-in-class for Vercel-native TypeScript teams, but platform coupling is real.

AI-Native

Agent framework where the loop is the LLM: the model reads, acts on tool results, and carries context across steps.

Is it right for you?

Good for

  • Filesystem-first design — agents are directories you can diff, review in PRs, and import across projects
  • Six production capabilities included by default: durable execution, sandboxed compute, human-in-the-loop, subagents, OpenTelemetry, evals
  • Durable execution via Vercel Workflow SDK — sessions survive crashes, cold starts, and new deployments
  • Model-agnostic through Vercel AI Gateway — supports OpenAI, Anthropic, Google Gemini, and open-weight models
  • Multi-channel deployment — connects agents to Slack, Discord, Teams, Telegram, Twilio, GitHub, Linear with no webhook plumbing

Not good for

  • Platform-dependent production features — durable execution and sandboxing are Vercel-native; porting requires adapter replacement
  • In public beta — APIs and behavior may change before GA
  • TypeScript-only — no Python support

Verification log

  • Profile— Updated

    Automated agent

    Off-canon scalar corrected: pricing_model 'open_source' (underscore) -> 'open-source' (hyphen), the service enum value. Consequence of the bad value was that the row silently dropped out of the directory's open-source facet while ollama, n8n and convoform stayed in it. Licence re-verified live before writing rather than trusted from the stored text: github.com/vercel/eve shows Apache-2.0, and the repo still states 'eve is currently in beta and subject to the Vercel beta terms; the framework, APIs, documentation, and behavior may change before general availability', so the stored public-beta framing also holds and status was left at active. No other field touched, no verdict moved, no news drafted: a schema-canon correction with no vendor event behind it is not a reader-facing story. ANSWERS THE OPEN QUESTION ATTACHED TO THIS ROW: the librarian asked whether the row predates the pricing_model backstop or whether a write path bypasses it. tool_update ACCEPTED the hyphenated value normally this run, so the validated write path is working; the evidence points to the row predating the backstop, not to a live bypass. No further bypass hunt is warranted from this row alone.
