The best AI agent for solo developers
By Marcell Havlik, founder of TODO for AI · Updated
You write the code, own the deploy, and have no one to review your PRs. The agent should run on your box, in your shell, with your tools. Here is how 16 tools score against what this job actually needs, and where each one fits.
Key takeaways
- Top pick. TODO for AI ranks first of 16 AI agents for solo developers, at 96% fit, followed by OpenHands (85%) and n8n (82%).
- What decides it. For solo developers the ranking weights model freedom and long-running work highest, and tools that cannot do the core job are not ranked at all (14 left out).
- Models. TODO for AI runs any provider, Claude, GPT, Gemini, Grok or a local Ollama model, on one plan. Pricing: free plan (Claude Sonnet only), then Starter $20, Pro $100 or Ultra $200 a month with any provider included.
- Benchmark. TODO for AI scored 89.9% on Terminal-Bench 2.1 with Opus 5.5 (high) (own harness, 80/89 tasks, 2026-10-08; not an official leaderboard submission).
- Not for you if. If you want AI completing your lines as you type, an editor-integrated tool beats every agent here. That is a different job from delegation, and many developers run both.
What solo developers actually need done
Solo developers are the best-served audience in this market, which makes the choice harder rather than easier. Every tool ranked here writes competent code. The differences that survive a month of daily use are which models you can reach, whether anything reviews the output, and what happens to your bill when a task runs for two hours.
This ranking weights model freedom and openness heavily, and almost ignores team features. It also rewards tools that keep working unattended, because the highest-value thing a solo developer can do with an agent is hand off the boring migration and go build something else.
Multi-file changes in an existing codebase, with the tests kept green.
Nobody reviews your work. A second model reading the first one is the closest thing to a colleague.
Migrations, dependency bumps, test backfills: work measured in hours, not prompts.
Token meters punish exactly the long autonomous runs that are most useful.

How we weighted it
Every tool carries one set of scores across 6 dimensions, used on every page of this site. A page for solo developers does not rewrite those scores, it weights them. Here is every weight, including the ones turned down:
The first job is multi-file work in an existing codebase, so anything without repo access is not ranked, whatever else it does well. Not ranked here: Lindy, Lovable, Base44, Notion, ClickUp, Asana, Copilot Cowork, monday.com, Zapier, Make, Airtable, Motion, Trello, Gumloop.
We build one of these tools, so treat this as an editorial argument rather than a measured verdict. The weights are all above and each tool's underlying scores are on its own comparison page, precisely so you can disagree with them.
