Why the edge:
- Reliability, OpenHands +47: 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).); T3 Code 43 (Local software. An install script and desktop and mobile apps from the vendor (20). ci.yml and windows-tests.yml run on the repository; pass state not read (15). GitHub issues and pull requests weren't read (GitHub's pages refuse these sessions), so that line is scored absent (0). Stable tags v0.1.5 to v0.1.7 with many nightlies, no changelog file (8). Version 0.1.7 (0). 20 + 15 + 0 + 8 + 0 = 43.)
- Schema & documentation, OpenHands +35: 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).); T3 Code 55 (Harness reading. User docs in the repository (managed policy, handoffs, providers, telemetry), AGENTS.md for contributors, a server other clients connect to (55).)
- Security & auth, OpenHands +29: 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).); T3 Code 35 (Harness reading. Product usage events go by default to ingest.t3.codes and PostHog, with hashed identifiers for your T3 Connect, OpenAI and Claude accounts, and relay traces to Axiom, which can include machine names and error text. Off with T3CODE_TELEMETRY_ENABLED=false or a managed policy. Disclosed in docs/user/telemetry.md, not the README (10 of 30). Permission modes and managed policies (12 of 20). No prompt-injection guidance (5). No audit log (5). No security policy file found (3). 10 + 12 + 5 + 5 + 3 = 35.)
- Agent ergonomics, OpenHands +18: 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).); T3 Code 60 (Harness reading. Remote control from phone or browser, portable handoffs between providers and managed policies for teams (60).)
- Transparency & trust, OpenHands +16: 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).); T3 Code 51 (MIT (30). docs/user/telemetry.md lists what is sent and what isn't, but includes hashed third-party account identifiers and the README doesn't mention it (15 of 30). No deprecation policy (5). Disclosed with an opt-out, on by default (12 of 20). 30 + 15 + 5 + 12 = 62.)
- Maintenance & community, OpenHands +10: 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).); T3 Code 75 (Commits and nightly tags on 6 November 2026 (30). More than three releases in 90 days (20). GitHub issues and pull requests weren't read (GitHub's pages refuse these sessions), so that line is scored absent (0). Current official apps and install script (15). CI on push (10). 30 + 20 + 0 + 15 + 10 = 75.)
