Freebuff vs Kiro: a full free day vs 50 credits a month
Kiro’s free plan is 50 credits a month that you cannot top up, and in November its paying users hit rate limits on prompts as short as "hi". Freebuff is free, every day.
In short
- Our verdict: Freebuff. We make Freebuff, so weigh that, but every claim below links to a source you can check.
- Kiro’s free plan is 50 credits a month, and free users cannot buy more. Every request spends credits, and complex tasks spend more.
- Paying users are hitting walls too. In the first two weeks of November, 35 rate-limit issues were opened on Kiro’s GitHub, against 10 in all of October, some failing on a prompt of just "hi".
- Loops can burn a month in hours. Users report 1,000 credits gone in a few hours to agent loops.
- Freebuff is free for a full day of work, every day. Unlimited messages in every hour-long session, a daily allowance with no monthly cap, and models that do not touch the allowance at all.
Kiro is AWS’s agentic IDE, and its spec-driven workflow is a genuinely good idea: write the requirements and the design, then let the agent work through the tasks. But it bills every step in credits, gives free users 50 a month, and has spent November fighting rate limits. If you want a coding agent you can use all day for free, Freebuff is the better choice.

What Kiro costs
Per Kiro’s pricing, the "perpetual Kiro Free tier" includes 50 credits a month, with open-weight models and Claude Sonnet 4.5. Pro is $20 a month for 1,000 credits, Pro+ $40 for 2,000, Pro Max $100 for 5,000 and Power $200 for 10,000, with extra credits at $0.04 each on paid plans.
Kiro’s billing docs say "Credits are consumed fractionally based on each request", so complex tasks cost more than simple ones, and pricier models multiply the cost. Add-on credits are listed as "Not available" on Free. When the 50 are gone, you wait for next month.
What Freebuff gives you for free
- Unlimited messages in every session. A session lasts an hour, and the agent can read, edit, test and retry as many times as it needs inside it. A loop never drains a month of credits, because there are none to drain.
- A published daily allowance with no monthly cap. Up to 30 hours a day in the US, and 21 in countries such as Canada, the UK and Germany. That is 10 hours a day of DeepSeek V4.1 Flash, refilled every day.
- Models that do not use it. Right now, Solar Mini 4 and Solar Pro 4 never touch your allowance, and new accounts in the US and other top-tier countries also get DeepSeek V4.1 Flash Fast without touching it.
- It runs where you work. The CLI sits next to the editor you already use, and there is a desktop app for Mac, Windows and Linux, the web workspace, and apps for iOS and Android.
What Kiro users are saying
Kiro has only a handful of Trustpilot reviews, so its GitHub issues are the better record. The recurring themes are limits and credits:
- Rate-limited on "hi". A November 10 issue: "Same error on IDE, CLI V2, CLI V3, and Web, even on first prompt 'hi'", with about 600 credits left. #12354
- Blocked at 40%. On November 11, a user hit rate-limit errors while their usage was "400 out of 1000". #12379
- A month gone in hours. In October, a user’s "entire quota of 1,000 credits was completely depleted within a few hours" by a background loop. #11937 In August, another reported "more than 1,000 credits were consumed by actions that were stuck in this looping behavior". #11151
- Hidden multipliers. An open October issue says newer Opus models "cost more credits than Opus 4.5/4.6, and the posted multipliers do not show it". #12082
- Automated replies to refund requests. A Pro Max subscriber in November reported Claude models unavailable and "refund requests receiving only automated replies". #12307
- A rocky history. At launch in 2025, Kiro added a waitlist and usage caps within days, and its first credit pricing was called "a wallet-wrecking tragedy". In July 2026, a flaw that let a poisoned web page run code on a developer’s machine was rated 8.8 and fixed.
What Freebuff users are saying
I took a risk And used your cli on my live project. I must say that it worked absolutely perfect even though I use various frontier models via subscription
I’ve fixed more bugs in one day than my other tools fixed in two weeks!
Where Kiro is strong
Kiro’s specs, hooks and steering files are a thoughtful way to keep an agent on track, its free plan includes Claude Sonnet 4.5, and it runs as an IDE, a CLI and on the web, with AWS behind it. If your team has the budget and likes spec-driven work, it is a serious tool.
Our verdict
Pick Freebuff. Kiro gives free users 50 credits a month with no way to add more, and even paying users are fighting rate limits and loops that drain their credits. Freebuff gives you unlimited messages in every session and an allowance that refills every day, in the terminal, on every desktop, in the browser and on your phone.
