List all the agentic and harness solutions available in last 365 days

A best-effort discovered catalog of 120 named AI coding agents and coding-agent harnesses that launched, previewed, went beta, reached general availability or were first open-sourced between 2 September 2025 and 2 September 2026 — 74 agentic solutions and 46 harnesses / frameworks. No authoritative registry exists, so treat coverage as broad rather than exhaustive.

Momentum builds through the window: July 2026 alone accounts for 24 launches — more than the entire Sep–Dec 2025 stretch (11) doubled — with the busiest single item, DeepSeek Harness, backed by 31 sources. youtube.com

Closely related names appear separately when sources name them separately: DeepSeek's harness shows up as four entries (Harness, Harness v0.1, DeepSeek Harness, DeepSeek Harness v0.1) around 10–13 August 2026. saassentinel.com

43 of the 120 records are corroborated by two or more sources; the remaining majority rest on a single write-up, such as OpenAI's open-sourced Codex Harness. fakta.co

Harnesses and runtimes are no longer a niche: they make up 46 of 120 records, from Prime Intellect's self-improving Prime Agent to mobile-first orchestrator beafk. futureparse.com

Method: web scan of official announcements, GitHub/project pages, news, press releases and tool roundups over 2025-09-02 to 2026-09-02, filtered to named standalone coding agents or reusable harness/runtime/CLI/orchestration products; model-only launches, isolated plugins/features, benchmarks and purely academic methods without a public implementation were excluded. 120 rows, one per normalized extracted product name; launch terminology is inconsistent, first-release dates can be ambiguous, small projects may have a single secondary source, and related names or editions may appear as separate rows. Interface and license fields were blank for every record and are shown blank. Bold product names mark entries with two or more sources.
