At a glance

A beta, self-hosted coding agent for teams already using Coder. It works from a web chat or API, can create approved workspaces, delegate parallel subagents, and use the models and tools configured by an administrator.

Good choice if

  • Teams that already run Coder and want one web interface for delegated coding work
  • Organizations that need centrally selected models, user permissions, cost controls, and inspectable activity
  • Parallel or automated jobs that should start from administrator-approved workspace templates

Check before choosing

  • Coder Agents is beta, and its Chats API is still experimental
  • It requires a self-hosted Coder deployment and administrator setup; it is not a lightweight tool for an individual project
  • Workspace isolation depends on the selected template and its network rules; broad template access is not a security sandbox by itself
See 2 more considerations
  • Graphical desktop and browser work are experimental and require a supported provider plus a desktop-enabled workspace template
  • Chat history can resume after a workspace is replaced, but there is no first-class file checkpoint or rewind feature

Getting started

Run Coder 2.33.1 or later, configure at least one provider and model, grant the Coder Agents User role, and prepare a clearly described workspace template. Developers then use the web chat; automations use the experimental Chats API.

Why it qualifies as a coding harness

This confirms category fit, not product quality. Every required criterion links back to first-party evidence.

Qualifies4 of 4 required criteria evidenced

  • Adaptive agent loop

    Documented

    The system repeatedly observes results and chooses the next action instead of following a fixed one-pass graph.

    EvidenceCoder Agents overview

  • Repository tool execution

    Documented

    The system can use tools to inspect and change a repository or its execution environment.

    EvidenceBuilt-in tools

  • Task-aware context management

    Documented

    The runtime assembles, updates, compacts, retrieves, or persists task-relevant context while work proceeds.

    EvidenceCoder Agents architecture

  • Model-independent runtime control

    Documented

    Permissions, budgets, interruption, policy, or stop controls operate outside the model's own text generation.

Public ecosystem signals

Source-native observations for exact mapped artifacts and reviewed stable release trains. Different units and populations stay separate, and missing coverage is never treated as zero.
