Input tokens are the code Mira reads; output tokens are the modernized code & tests it writes. Launch pricing — may change.

Questions

Pricing, answered.

What’s a token?
A token is the unit of usage — very roughly a few characters of code or text. Mira spends input tokens reading and analyzing your code, and output tokens writing the modernized code, tests and reports. You only pay for what Mira actually uses. As a rough rule of thumb, one line of legacy code is on the order of 8–70 tokens of work depending on how deeply you modernize it — the calculator above turns lines of code into an estimate.
Do tokens expire?
Pay-as-you-go credit never expires — top up once and draw it down whenever you like. The Free and Pro plans include a monthly token allowance (250,000 tokens on Free; 40M input + 20M output on Pro) that resets at the start of each billing month.
What if I go over my included tokens?
On Pro, anything beyond the included 40M input / 20M output is billed at the lower committed rate of $1.20 / 1M input and $2.40 / 1M output — cheaper than pay-as-you-go, so heavy months stay predictable. On pay-as-you-go there’s no overage concept at all: you simply spend your balance and top up when it runs low. Nothing auto-charges without credit on file.
Can I switch plans?
Yes — upgrade, downgrade or cancel anytime from your account, no lock-in. You can even run pay-as-you-go credit alongside a Pro subscription, so a big one-off migration never blocks your team. Enterprise terms are set with sales.
Is there a free tier?
Yes. Free is $0 forever and includes 250,000 tokens per month plus one full project review on public repositories — enough to see a real security + tech-debt report and your first reviewed pull request. No credit card required.
