Best AI coding agents for Free Plans (2026)

For free plans, Amp is our pick: What the free plan allows is the deciding factor, and here the two are far apart. Developers who want real agent work without paying yet: what a free tier actually allows (requests, models, a daily allowance, or nothing until you bring your own key) rather than whether a free badge exists. Below is the full ranking and the tradeoffs, or read how we score.

×5 What the free plan allows: The question is never "is there a free plan" but what it allows: a resetting daily allowance on a strong model reads very differently from a handful of requests a month.×4 Bring your own API key: A free tool that accepts your own API key turns "free" into "you pay the model provider directly at list price", often the cheapest honest route.×3 Cheapest paid plan (monthly): Free tiers run out; the price of the next rung up is what a free-tier evaluation is really shopping for.×2 Runs local models: Running a local model removes the usage meter entirely, at the cost of your own hardware.
