Watch out: Suggestions are strongest on common patterns and weakest exactly where your codebase is unusual. Pro and above bundle a monthly credit allowance, so premium-model work is metered on top of the seat.

Strong fit. The assistant that already has your AWS account in context, which makes it the practical choice for questions about infrastructure you actually run.

Watch out: Credits burn quickly on iteration, and a generated app is a prototype until someone reads it. Pro is sold in token tiers from 10M a month up, so its price is the entry rate rather than the bill.

Watch out: Autonomy means less visibility into what changed — review discipline matters more, not less. Larger organisations may still be routed through sales rather than self-serve.

Watch out: Less capable at whole-repository reasoning than the purpose-built agents. It is also reachable through the Google Developer Program, which is a separate membership with its own terms rather than a tier on this ladder.

Strong fit. The standard framework for wiring a model to your own data, with tracing so you can see why it answered as it did.

Watch out: A developer library, not an application. Both LangSmith tiers meter traces above a monthly allowance, so the seat price is a floor rather than the bill, and the free tier is one seat only.

Watch out: Smaller ecosystem and fewer integrations than the US majors. Every plan bundles a monthly allowance of API credits — $10 free, $30 on Pro, $15 on Education — and API use beyond it is priced per token on the API tab of the same page.

Watch out: The AI writing is the smaller half; most of the value is the publishing. There is nothing between the free tier and $450 a month, so the decision is whether five editors is enough rather than which plan to buy.

Watch out: Generated tests can assert current behaviour rather than correct behaviour, which passes and proves nothing. One plan sold in credit packs rather than a ladder: the price is the pack you pick, it is designed for up to 30 users, and overage is capped at a figure you set.

Watch out: Individual plans were retired in 2026, so the entry price is a team one — flat, not per seat, which makes it unusually cheap per head on a large team. What you buy is a usage allowance rather than seats: $20 buys $20 of it, and anything beyond is topped up pay as you go.

Watch out: It withdrew its free tier and every individual plan during 2025 — there is no way for one developer to buy it any more, only a team. Both tiers are annual and neither has a checkout: the button on each is Get a quote.
There is no single answer, which is why this page lists 27 rather than one. 7 of them are built for the job they are listed under. Start with a free one.
Which of these are free for developers?
23 of the 27 have a genuine free plan: ChatGPT, Claude, CodeRabbit, Cursor, GitHub Copilot, Replit, Amazon Q, Bolt.new, Codestral, DeepSeek, Devin, Figma AI, Gemini Code Assist, JetBrains AI, LangChain / LangSmith, Le Chat (Mistral), Meta AI, Mintlify, Qodo, Qwen, TypingMind, Venice AI, GitHub. Free means a real free tier, not a trial.
How were these picked for developers?
Every tool on this site is tagged with who it suits. This page is that filter, nothing more — no tool was added or promoted for being here, and placement is not for sale.
