- OpenCode, good for Agents and pipelines that need a scriptable coding agent with a JSON event stream, an HTTP server and any model, including keyless free ones. Ahead on Reliability, 72 against 43; Schema & documentation, 88 against 45; Agent ergonomics, 79 against 50; Maintenance & community, 81 against 75; Transparency & trust, 71 against 57. Also Free to start without a card.
- Sculptor, good for Developers who want parallel coding agents in isolated workspaces and are fine with a research preview. Also No incidents deducted, where OpenCode loses 4 points for them.

Why the edge:
- Schema & documentation, OpenCode +43: OpenCode 88 (A JSON Schema for the config file at opencode.ai/config.json, and an OpenAPI 3.1 spec for the 1.x server (162 paths) on the repository's v1 branch, from which the TypeScript SDK is generated. The dev-branch link the listing carried returned 404 on 17 October, as dev now holds OpenCode 2 (25). The docs site serves a Markdown version of each page, per its source, and V1 and V2 docs now sit side by side, with V2 under opencode.ai/v2/docs (10). Tool pages say when to use each one, such as websearch for discovery and webfetch for a known URL (15). Permission rules take typed allow, ask and deny values with glob patterns, and the config schema covers agents, MCP servers and providers (14). Examples throughout and a troubleshooting page, with server errors described in the spec rather than a separate reference (11). A dated changelog at opencode.ai/changelog and GitHub releases (13).); Sculptor 45 (Harness reading. A README, specs and agent docs in the repository; no API reference (45).)
- Reliability, OpenCode +29: OpenCode 72 (Read as a local package, graded on the 1.x line that `npm i -g opencode-ai` and the opencode.ai/install script put on a machine. `opencode-ai` 1.19.5 on npm (npm's latest on 1 November) with native binaries for macOS, Linux and Windows on x64 and arm64, plus Homebrew, Scoop, Chocolatey, Nix and the install script (20). A test workflow runs on the repository. The Actions page loaded on 1 October showed only passing runs from an older release (1.3.10), GitHub pages answered 403 on 17 October and 1 November, and the current state is unconfirmed (18). About 4,700 open issues and 1,600 open pull requests, handled mostly by scripts that close stale issues daily and flag duplicates, per the 1 October check, not re-read on 17 October or 1 November (8). Releases come almost daily with notes on GitHub and a changelog page. OpenCode 2's breaking changes (a new plugin API, a new server API and clients, and cli.json in place of tui.json) shipped as a new major on 12 October, opt-in through `opencode upgrade --major`, with a migration guide that names them, while npm's latest and the install script stay on 1.x. The 1.19.4 and 1.19.5 commits change no SDK code and mark no breaking change, but the 1.x release notes weren't read for a breaking-change section (11). 1.19, stable (15).); Sculptor 43 (Local software. Desktop downloads for Mac (Apple Silicon), Linux and Linux ARM64 (20). checks.yml and a PR gate 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). sculptor-v tags up to v0.49.0, no changelog file (8). 0.x and labelled a research preview (0). 20 + 15 + 0 + 8 + 0 = 43.)
- Agent ergonomics, OpenCode +29: OpenCode 79 (Harness reading of the framework line, scored on what an agent or pipeline driving it has to supply. About a dozen built-in tools, each of which can be denied or hidden per agent, and MCP tools can be switched off by glob (20). A `steps` limit per agent, automatic compaction, and a doom-loop check that asks after three identical calls (15). `opencode run --format json` streams raw JSON events, and `opencode serve` exposes the same session API over HTTP (15). Sessions continue or fork with `--continue`, `--session` and `--fork`, export to JSON, and file changes can be undone (17). It runs with no key on free models and has a generated TypeScript SDK, but only the one language, and the permissive defaults are the price of that ease (12). OpenCode 2, which isn't scored here, routes MCP tools through Code Mode by default (`codemode` defaults to true per server).); Sculptor 50 (Harness reading. Workspaces as isolated copies, review and merge back, and built-in skills (50).)
- Transparency & trust, OpenCode +14: OpenCode 71 (MIT (30). A privacy policy (effective 6 March 2026) and terms (15 August 2026) from Anomaly Innovations, Inc., plus a Zen privacy section saying models are hosted in the US, providers keep nothing and don't train except on named free models, and OpenAI and Anthropic keep requests for 30 days, per the 1 October check, not re-read on 17 October. The general retention line is as long as necessary (22). Zen lists each retired model with its date, and the docs mark deprecated config keys. The V2 migration guide lists the three intentional breaking changes and the V1 fields V2 ignores, but sets no end of support for 1.x (15). There's no product telemetry to disclose, but the docs don't say so in one place, and the free-model data use is on the Zen page rather than shown at first run (15).); Sculptor 57 (MIT (30). Consent-based telemetry documented in the repository (18 of 30). The README warns of drastic changes during the research preview, with no deprecation policy (5). Opt-in telemetry (20). 30 + 18 + 5 + 20 = 73.)
- Maintenance & community, OpenCode +6: OpenCode 81 (1.19.5 on npm on 2026-10-28, 4 days before the check, and v2.2.5 tagged on 30 October (30). 30 releases on the 1.x line (1.18.12 to 1.19.5) in the 90 days to 1 November, plus 44 v2 tags (20). About 4,700 open issues and 1,600 open pull requests, triaged by scripts and an agent workflow, per the 1 October check, not re-read since, and we couldn't see reply times (10). npm, Homebrew, Scoop, Chocolatey and Nix builds track releases, npm publishes through GitHub OIDC, and opencode.ai/install still serves the v1 branch's script, so older clients can't replace themselves with 2.x by accident (14). Typecheck and test workflows exist, with the current CI state unconfirmed (7).); Sculptor 75 (Commits on 6 November 2026 and frequent tagged versions (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; the README says Imbue can't take many outside contributions yet (0). Current official downloads (15). CI on pull requests (10). 30 + 20 + 0 + 15 + 10 = 75.)
