Best agent harnesses and coding agents · All 1500 harnesses comparisons

Which one, for what

Emdash D

Best for Developers who want parallel agents in worktrees, fed from their issue tracker, locally or over SSH.

Also in its favour

  • No key needed to call it
  • No incidents deducted, where OpenHands loses 7 points for them

Watch for

Telemetry on unless turned off in Settings or with TELEMETRY_ENABLED=false

OpenHands BB

Best for Teams that want to self-host a coding agent with a web UI, per-conversation Docker sandboxes and scheduled or webhook automations, or embed the agent through a Python SDK and REST API.

Ahead on

  • Reliability, 90 against 55
  • Schema & documentation, 90 against 55
  • Agent ergonomics, 78 against 55
  • Security & auth, 64 against 38
  • Maintenance & community, 85 against 70
  • Transparency & trust, 67 against 54

Also in its favour

  • Agent-ready, a grade of BB or better

Watch for

Confirmation mode is off by default in Agent Canvas, and the npm install gives the agent the host's whole filesystem

Why the edge

Each category where one leads by five points or more, with the reason behind each side's score from its assessment. The numbers are in the table below; this is what they stand for.

Reliability OpenHands +35

Emdash 55

Local software. Homebrew cask and installers for macOS, Windows and Linux (20). A code-consistency check and release workflows; no test workflow found (10). GitHub issues and pull requests weren't read (GitHub's pages refuse these sessions), so that line is scored absent (0). Stable tags to v1.2.11, release notes on GitHub (10). Version 1.2.11 (15). 20 + 10 + 0 + 10 + 15 = 55.

OpenHands 90

Read as a local package. Official npm package @openhands/agent-canvas (Node 24 or later, plus uv), a Docker image on GHCR and openhands-sdk on PyPI (Python 3.12 or later) (20). A CI workflow (ci.yml) runs on main beside desktop, Docker and end-to-end workflows; the runs passed on every load on 1 October, and GitHub's pages refused us on 1 November, so the award rests on that check (25). 456 open issues and 395 open pull requests with priority labels and a high-priority Cloud resume bug (#17664), per the 1 October check, not re-read on 1 November (18). Dated release notes for every Canvas version and a written SDK rule of at least five minor releases before a public API or REST contract is removed, which the SDK followed on 28 October when it dropped the ACP curated model lists at their stated 1.59.0 deadline, but the Canvas CHANGELOG.md still stops at 1.0.0-alpha.2 (12). Canvas is 1.34.0 and the SDK 1.59.0, and the README's beta badge was removed on 23 October 2026 (commit 4d1c4d1, noted in the 1.33.0 release notes), so the product is no longer labelled beta. Only the Apps extension API keeps a beta label (15).

Schema & documentation OpenHands +35

Emdash 55

Harness reading. Docs site and a workspace server package (55).

OpenHands 90

The Agent Server REST API has an OpenAPI 3.1 spec in the docs repository (40 paths, still labelled 0.1.0), the Cloud API has another (155 paths), SDK models are Pydantic-typed and there's a TypeScript client (25). llms.txt at docs.openhands.dev (551 lines on 1 November), with no CLI, local GUI or V0 pages in it (10). The docs have a when-to-use page and examples of good and bad task instructions. On 23 October the Deprecated Projects group (local GUI, CLI, V0) was taken out of the navigation and links to it reworded towards Agent Canvas, though the pages stay reachable by URL and the SDK architecture page still links the CLI repository (15). Confirmation policies, security analysers and MCP configs are discriminated Pydantic unions with validators (13). SDK examples are checked by a CI workflow and there are troubleshooting pages, but we found no error reference for the Agent Server (12). Dated release notes for each Canvas version in the docs (1.25.0 to 1.34.0 added since 1 October), and release tags (15).

Security & auth OpenHands +26

Emdash 38

Harness reading. Telemetry is described as optional and disabled in Settings or with TELEMETRY_ENABLED=false, which reads as on by default (15 of 30). Worktree per task and remote machines over SSH (10 of 20). No prompt-injection guidance (5). No audit log (5). No security policy file found (3). 15 + 10 + 5 + 5 + 3 = 38.

OpenHands 64

Harness reading of the framework checklist, as for goose and the other agent harnesses. 30 for what leaves the machine by default, 20 for approvals and sandboxing, 15 for prompt-injection posture, 15 for audit and 20 for the security programme. Agent Canvas still sends a canvas_install event to PostHog through z.openhands.dev on first use "regardless of consent" (telemetry.ts header, re-read on 1 November), and the consent banner's box is still defaultChecked. AGENT_CANVAS_DISABLE_TELEMETRY=1, --disable-telemetry, VITE_DO_NOT_TRACK=1 or the browser's Do Not Track setting stops all of it, the last since 1.26.0 (15). Confirmation policies (always, never, at or above a risk level) and a Docker sandbox per conversation exist, but Canvas still starts with confirmation_mode: false and the npm install runs on the host with full filesystem access. No network egress controls found. Local listeners bind to 127.0.0.1 with an injected session key, and since SDK 1.52.0 (5 October) DockerWorkspace publishes its ports on loopback (12). LLM, Invariant and GraySwan risk analysers and a policy-rail module, documented, all advisory (11). Conversation event logs, completion logs and OpenTelemetry tracing through Laminar, with hosted Laminar setup documented on 16 October (13). Security programme. openhands.dev's security.txt expired on 28 October 2026 (re-read on 1 November), though the responsible-disclosure policy it names still loads. A Vanta-hosted trust page per the 1 October check, and the git diff injection published as an OpenHands advisory with a CVE. CVE-2026-112346, the SDK's unauthenticated sandbox server, was published by VulnCheck on 26 October with no OpenHands advisory found. No bug bounty found. 13, down from 15 for the expired file, read as shopware's and tokeneconomizer's expired files are (still credited for the policy behind them, less than a valid file).

Agent ergonomics OpenHands +23

Emdash 55

Harness reading. Issue intake from Linear, GitHub, Jira and others, diff review, pull requests and CI checks in one place, local or over SSH (55).

OpenHands 78

Harness reading of the framework line, scored on what an agent or pipeline driving it has to supply. The default agent carries three tools (terminal, file editor, task tracker), and filter_tools_regex trims MCP tools before they reach the model (23). Stuck detection is on by default and a condenser compacts long histories, but Canvas leaves max_iterations unset and we found no cost cap (15). Headless runs go through the SDK, the Agent Server REST API or the Cloud API with typed events, and the old CLI's --headless mode is unmaintained (14). Conversations persist and resume, and a Docker conversation keeps its workspace and history when the container is replaced (16). Python SDK and TypeScript client, but the quickstart needs Node 24 and uv, and the defaults skip both confirmation and the sandbox (10).

Maintenance & community OpenHands +15

Emdash 70

v1.2.11 on 6 November 2026 (30). v1.2.9, v1.2.10 and v1.2.11 within two weeks (20). GitHub issues and pull requests weren't read (GitHub's pages refuse these sessions), so that line is scored absent (0). Current installers and Homebrew cask (15). Release workflows, no test CI (5). 30 + 20 + 0 + 15 + 5 = 70.

OpenHands 85

Agent Canvas 1.34.0 on 2026-10-27 and SDK 1.59.0 on 2026-10-28, by the repository tags (30). 29 Canvas releases (1.9.0 on 3 August to 1.34.0) and 33 SDK releases (1.40.1 on 5 August to 1.59.0) in the 90 days from 3 August, not counting the security rebuild tags (20). Issues labelled by priority, but 456 open issues and 395 open pull requests and no visible reply times per the 1 October check; GitHub's pages refused us on 1 November (16). npm, PyPI and GHCR packages current per the 1 October check (the registries didn't answer from our shell on 1 November). The unmaintained openhands CLI is gone from the docs navigation and the pricing page but its pages remain (10). CI on main, Dependabot, a security scan and an API-breakage check on the SDK, and security rebuilds of older images (agent-canvas 1.23.0-r3, agent-server 1.49.5-r3, 29 October) (9).

Transparency & trust OpenHands +13

Emdash 54

Apache 2.0 (30). A telemetry page on the docs site (not read) (18 of 30). No deprecation policy (5). Disclosed with an opt-out (15 of 20). 30 + 18 + 5 + 15 = 68.

OpenHands 67

MIT across Canvas, SDK, tools and Agent Server (30). The privacy policy (effective 3 September 2025, re-read on 1 November) doesn't separate the open-source stack from the Cloud service, keeps data as long as reasonably necessary, allows training on content from the Services and has no subprocessor list (12). A written SDK deprecation runway of five minor releases, kept on 28 October when the ACP model lists were removed at their 1.59.0 deadline, and the CLI's unmaintained notice in its README without a date on the page (15). The consent prompt calls the data anonymous and the Docker page documents AGENT_CANVAS_DISABLE_TELEMETRY, but no user-facing page mentions the install event sent before consent (10).

How the scores have moved

Verdicts

Emdash

A mature open-source app for parallel coding agents in Git worktrees, with issue intake from a dozen trackers and remote machines over SSH. Telemetry is on unless you turn it off, and no test workflow was found in the repository.

OpenHands

A self-hosted coding agent with a typed SDK, an Agent Server API and a Docker container per conversation on request. Agent Canvas still starts with confirmation off on the host's filesystem, sends an install event before asking consent, and a critical SDK sandbox flaw fixed in October was published by a third party.

Before you call either

Emdash

  1. Launch with TELEMETRY_ENABLED=false if you don't want telemetry
  2. Use the SSH mode to keep agents on a remote machine

OpenHands

  1. Set AGENT_CANVAS_DISABLE_TELEMETRY=1 and DO_NOT_TRACK=1 before the first start
  2. Start Canvas with OH_CONVERSATION_RUNTIME=docker or use the Docker image. The npm install runs the agent on the host
  3. Turn on confirmation mode with a risk threshold. Canvas starts with it off
  4. Pin openhands-sdk and openhands-workspace at 1.52.0 or later so DockerWorkspace binds to loopback, and set OH_SESSION_API_KEYS_0 on any reachable Agent Server
  5. Use the SDK or the Agent Server API for headless runs. The openhands --headless CLI is no longer maintained
