Verdict

Amazon Kiro offers a free tier ("Free"). We are not publishing a free-tier verdict for Windsurf. The page we cite for Windsurf does not name it when we last looked, on 2026-11-05. We are not comparing the two pricing histories.

A verdict here is not a fixed property of the vendor. A one-off pricing event demotes a vendor while its recorded date falls in the last 180 days and then lapses on its own, with nothing about the vendor having changed; a standing condition — a free tier withdrawn and not restored, a product retired — does not lapse with time. A badge carrying a date states the record it rests on; a badge with no date rests on no record in force.

The Free plan ($0) includes a "Light quota to code with agents", "Limited model availability", "Unlimited inline edits" and "Unlimited Tab completions", with quotas that reset daily and weekly. Pro is $20/month, Max $200/month, and Teams "$80/month for team plan + $40/mo per full dev seat"; paid plans can buy extra usage at API list prices. Pro subscribers on the old $15/month price keep it indefinitely.The page we cite for this offer does not name it when we last looked, on 2026-11-05, so we cannot confirm these terms today.
