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.
