Introducing Harness Atlas
A dated guide to desktop, web and mobile AI agent environments, with official model-provider harnesses, independent tools, pricing and integration evidence in one interactive report.
Codex, Claude Code, Antigravity, Mistral Vibe and a growing field of independent agents each bring a different bench to the workshop. Choosing a fleet means comparing more than a model score: operating-system support, subscription access, tools, dispatch interfaces and observable usage all matter.
We have brought that landscape into Harness Atlas: 43 harness and access profiles, 36 model snapshots and 210 primary references. Official model-provider environments come first, followed by vendor platforms and community or independent harnesses. The compact comparison grid lets you scan capabilities and click into the caveats and evidence.
The platform audit covers Windows, Linux, macOS, web, Android and iOS, with native execution separated from hosted access and remote companions. Model cards distinguish verified specifications and access from benchmark coverage.
The report’s facts were last gathered on 2 October 2026. It is a research snapshot, not a live price feed, a market-share ranking or proof that every integration has been tested. Benchmark conditions differ, and subscription entitlements need checking before purchase.
For RelayHall, the opportunity is a shared workplace: keep workers in their supported harnesses, give them scoped context and skills, and bring artifacts and evidence back to the same board. An external orchestrator and harness-specific adapters can choose workers and track what each provider exposes. Complete quota visibility and universal adapters remain things to qualify, not promises.
The workflow tour and current roadmap explain RelayHall’s available behavior and what remains planned.
