Raven is EverMind-AI's Apache-2.0 "harness of harnesses": a self-hosted host agent that plans work as a DAG and orchestrates its own Research, Code, Design, and Oncall agents alongside Claude Code and Codex.

**Raven pairs one of the more interesting architectures in this category with its most instructive launch failure: the authors posted AI-generated comments to their own Hacker News thread, and the pitch's "recursive self-improvement" is, as one commenter put it, loops.**

## What it is

A self-hosted platform where a Host Agent decomposes a task into a DAG and dispatches the nodes to built-in agents (Raven-Research for deep research, Raven-Code for software development, Raven-Design for visual design, Raven-Oncall for unattended automation) or to external harnesses such as Claude Code and Codex.
It ships sandboxing, sub-agents, channels, Docker deployment, and trajectory replay, plus Evolver, a separate tool that consumes Raven as a library and evaluates candidate harness changes.
The README claims its agents beat Claude Code on both quality and cost in its own ArtifactsBench benchmarks, which are self-published.
Apache-2.0, self-hosted, by EverMind-AI, with a technical report released as its own GitHub release on 2026-09-27.

## Status

Active and very early: 5,213 stars and 149 forks as of 2026-10-05, created 2026-05-21, with 35 contributors and v0.2.4 out on 2026-10-03 after five releases in September.
The Show HN thread from 2026-09-29 drew 55 points and about 51 comments, and it is where the launch went wrong: dang, Hacker News's moderator, asked the authors to stop posting AI-generated or AI-edited comments, which site rules prohibit.
The same thread produced the sharpest one-line critique of the positioning: "it is loops", with no weight updates anywhere in the system.

## Strengths

- The DAG-planning host over heterogeneous agents (its own four plus Claude Code and Codex) is a design most columns approximate with a lead agent and optimism.
- Trajectory replay provides run-level audit, the feature Atlas built an entire product around, included here.
- Evolver, which treats the harness itself as the thing under test, is the most original idea in this batch of entrants.
- Shipping velocity: five releases in September 2026 plus a technical report.

## Cautions

- The launch carried a moderation warning about AI-generated comments, which is exactly the trust failure an agent company cannot afford.
- The recursive-self-improvement framing oversells: the self-evolution mechanism the README describes is generate-and-test over candidate changes, which is loops, and I found no training-loop evidence anywhere in the sources.
- The benchmark claims (beating Claude Code on quality and cost on ArtifactsBench) come from the project's own dashboards and should be treated as marketing until someone reproduces them.
- 0.2.x versioning with 92 open issues as of 2026-10-05: expect API churn.

## Pricing

Free and open source under Apache-2.0, self-hosted on your own hardware or Docker host.
No hosted tier recorded and no Raven bill.

## Compared to

- [Agent Swarm](../agent-swarm/index.md): the other self-hosted platform that turns orchestration into Docker-isolated workers and pull requests; choose Agent Swarm for intake-to-PR pipelines, Raven for DAG-planned heterogeneous teams with its own agents.
- [oh-my-codex](../oh-my-codex/index.md): the single-CLI enhancement path; choose it for Codex-only depth, Raven for multi-agent breadth.
- [The Perfect Orchestrator](../the-perfect-orchestrator/index.md): lead-and-worker tmux with adversarial verification; choose it for minimal infrastructure, Raven for sandboxing, replay, and a platform.

## Bottom line

**Recommended for self-hosting teams who want DAG-planned heterogeneous agents and will independently verify both the benchmarks and the comments.**
Not for anyone who needs a clean provenance story today or stable APIs before 1.0.

## Changes
