AI Coding Agents

AI pair programmers, agents, and editors that ship code. Browse the 7 parent tools below — each has a dedicated page with up to 10 indie or bootstrapped alternatives, plus pricing, founders, and where applicable, open-source flags.

Cursor and GitHub Copilot defined the category, but the indie space has gotten serious — Cline, Aider, Continue, Zed AI, and the agent-style players (Devin, OpenHands, Sweep) have splintered the market by use case. The decision is no longer 'which autocomplete' — it's 'which agent, in which workflow, with which model.'

What to look for

Editor integration that matches your existing setup, not a brand-new IDE
BYO-key + open-source model support — you'll want it eventually
Codebase indexing that survives a 100k-file repo
Diff-first UX: every change should be reviewable before it touches your tree

Common gotchas

Per-message pricing that runs up faster than you think on an agent loop
Background indexing that sends your full repo to a third party — confirm the privacy posture
Models silently swapping when you hit a usage cap
