A decision for a beginner, not a spec sheet. Scores are our weights. Prices are the public plans, and anything marked verify on the tool page should be re-checked before you pay.
Pick Kiro if you want a web app or automation you will keep in a repo and review as a diff.
Pick Windsurf if you want an editor agent at $20 with frontier models and cloud agents.
An agentic IDE that turns a prompt into a spec, then into a diff.

Price on the pricing page. Credit count on the billing docs.
Individual
$100/user/mo
Verified5,000 credits a month. The same feature set as Power, including specs, custom subagents, powers, and hooks.

Free
VerifiedLight agent quota, limited models, unlimited inline edits, and unlimited Tab. Quota size is not published.
Price and qualitative limits are from the Devin pricing page. The missing number is stated, not invented.
Individual
$20/mo
VerifiedDaily and weekly quotas, frontier models, free use of SWE-2, Devin Cloud, and extra usage at API pricing. One user. Quota size is not published.
Devin docs describe Pro as the entry individual plan at $20/mo. The pricing page lists free use of SWE-2 and does not print an end date for it.
Individual
$200/mo
VerifiedEverything in Pro with a significantly larger weekly quota and no daily cap. The quota multiple is not published as a number.
The no-daily-cap rule is on Devin's self-serve plan docs. The pricing page says significantly higher quotas and does not print a number.
Plan credits renew at the start of the next billing cycle. Paid subscriptions are processed on the 1st of each calendar month. Unused plan credits do not roll over. Add-on credits, which are paid plans only, last 12 months.
On Free, wait for the monthly reset. Add-on credits cannot be bought on this tier, and Kiro Web is not included.
Pro has daily and weekly quotas. Max has a weekly quota and no daily cap. Cognition does not publish the size. Past the quota, paid plans can buy extra usage at API pricing.
Check the in-app quota before you assume you need a new tool. Pro resets daily and weekly. Max has no daily cap, so a heavy afternoon may not clear overnight.
Kiro Pro and Windsurf Pro are both listed at $20/user/mo.
Kiro is for a web app or automation you will keep in a repo and review as a diff, developers who want requirements and tasks written down before the agent edits, and a published monthly credit number, instead of an unpublished quota.
Windsurf is for an editor agent at $20 with frontier models and cloud agents, developers comparing Windsurf with Cursor's current plans, and people who still search for Windsurf and need the current product name.
Kiro scores 2 out of 5 for someone who does not want to read code. Windsurf scores 1 out of 5. Kiro has the higher no-code score. Specs are written in plain language, and you still end up reading a diff. If code on screen is a dealbreaker, use a browser builder. You are in an IDE. Do not start here if you wanted a form.
Kiro: 50 credits a month on the perpetual free tier, with Claude Sonnet 4.5 and open-weight models, subject to rate limits. Add-on credits are not available. Kiro Web is not on this plan. Windsurf: A light agent quota, limited model access, unlimited inline edits, and unlimited Tab. Cognition does not publish the quota as a number.
