// how it works

How it works

  1. Define the job

    Research, coding, browsing, or ops — agents work best with a clear goal.

  2. Pick a framework

    From no-code builders to code-first SDKs, match complexity to the task.

  3. Give it tools

    Web search, code execution, and APIs are what make agents useful.

  4. Run and supervise

    Watch the trace, approve consequential actions, iterate.

// features

Why people love it

LLM-powered

Large language models drive its smartest features, locally or via API.

Evaluations

Benchmarks keep agent quality measurable.

Self-hosted

Run agents on your infra with your keys.

Model agnostic

Swap frontier models as better ones appear.

Observability

Traces show exactly what the agent did and why.

Human in the loop

Approval gates for actions that matter.

Questions, answered

Who maintains deer-flow?

It is an open-source project at bytedance/deer-flow with 11,569 forks. Check the repo's contributors and recent commits to see how active maintenance is.

Is deer-flow free for commercial use?

MIT licensed — use it commercially, no strings attached.

Do I need to code?

Builders exist, but code-first frameworks go further.

What does it cost to run?

Model API bills dominate; self-hosted stacks cut that sharply.

Are agents reliable enough?

For bounded tasks with supervision, yes. Fully autonomous money-moves still need guardrails.
