# Best Coding agents with autonomous

> Source: https://theagentsindex.com/best/coding-agents/autonomous (curated, quality-gated, re-verified)

16 of the 25 coding agents in this index qualify with autonomous — every one a Published, quality-gated listing, not a scraped row.

Across the set: 12 of 15 with known API status (80%) expose a public API, paid plans span $1.25–$100, and 11 offer a free or freemium tier.

16 of 16 carry a fact-verification date; the freshest check is 2026-08-25.

"Autonomous" covers two different products here, not one skill: agents that work unsupervised on an existing codebase and hand back a reviewed pull request (Claude Code, Devin, OpenHands), and prompt-to-app builders that generate a new, deployed application from scratch with no existing repo (Bolt.new, Replit Agent) — decide which job you have before comparing them on the same table.

## Methodology

Assembled programmatically from the live index: every entry is a Published, quality-gated listing in Coding agents carrying the "Autonomous" tag, ranked by tier then name. The numbers (16 tools, 80% of known with an API, paid plans $1.25–$100) are computed from the structured facts on those listings — this page exists only because the underlying data clears the density gate.
