The coding-agent ecosystem

Six zones covering every coding-agent paradigm. Read /systems/agent-execution-systems first if you need the architectural depth on planning loops, tool dispatch, sandbox isolation, and MCP/memory integration. Pair with /frontier/coding-agents for the momentum view.

Autonomous open-source agents

The category leaders by paradigm. OpenHands has the longest track record + most stable production deployment. OpenClaw is the velocity leader (350k+ stars after April 2026 release; foundation governance). Goose is Block's MCP-first contender, lighter and more extensible.

Surgical-edit CLI

Different paradigm — git-integrated CLI editor for tight-control workflows. Aider holds this niche; mature, stable, well-loved by developers who want the agent under their command rather than driving the workflow.

IDE-resident agents

Live inside VS Code (or compatible IDE). Cline picked up Roo Code's user base after that project shut down in May 2026 — current frontrunner for autonomous-task IDE agents. Continue covers a broader surface (chat + autocomplete + commands) at the cost of less aggressive autonomous-task quality.

Closed-source flagships

The polished commercial offerings. Claude Code is Anthropic's premium agent; Cursor is the IDE-as-agent product. Both deliver capability ceilings the open-source category can't match yet — but at subscription-tier cost and without self-hostability.

MCP-native infrastructure

The MCP servers most coding-agent deployments wire in. Filesystem MCP for file access; Git MCP for repo metadata. Pair with any of the agents above to get the canonical /stacks/local-coding-agent capability surface.

Shutdown + migration tracker

The agent ecosystem remains volatile. Roo Code shut down May 15, 2026 — listed here as a deliberate ecosystem-volatility signal. Migration target: Cline. Bet infrastructure on stable upstreams; track the volatile ones.

Best agent stack by goal

Self-hosted autonomous coding on private codebase: OpenHands + Mem0 + filesystem/git MCP + vLLM + RTX 4090. See /stacks/local-coding-agent.
Latest features + Anthropic-style reasoning: OpenClaw + same MCP/memory layer + Claude Sonnet via API (or local 32B AWQ). The cloud-Claude hybrid pattern.
MCP-heavy enterprise workflows: Goose + per-team MCP allowlist + audit logs. Block's enterprise governance is real — the right pick when MCP extensibility is the primary requirement.
Surgical edits with tight control: Aider + Ollama + git. Each session = one focused commit. The right pick when you want the agent under command rather than driving.
IDE-resident autonomous tasks: Cline + Ollama. The Roo Code migration target; lives inside VS Code; designed for “help me with this task while I keep working in the same window.”
Everyday IDE assistance (broad surface): Continue + Ollama. Chat + autocomplete + commands; less autonomous-task focus than Cline; broader ergonomics.
