Free tools. Paid API, when you need it.

Rate limiting

Limits are enforced per key per month. Bursts are smoothed with a short-window counter so a single client cannot exhaust a shared quota.

Authentication

Pass the key in an X-Api-Key header. Keys are scoped to a plan and can be revoked without changing your account.

Data handling

API payloads are processed in memory and discarded after the response. We do not log request bodies.

Keep the lights on

Every tool is free. Tips keep it that way.

No subscriptions, no locked features. If a tool saved you time, you can drop a small tip — it pays for hosting and the next batch of tools.

Tips are not connected in this deployment. Set NEXT_PUBLIC_TIP_URL to your Stripe Payment Link to enable this panel.

Pricing questions

No hidden fees, no per-seat pricing.

Yes, with no usage limit and no account. API plans exist for programmatic access only. You never need to pay to merge a PDF or generate a password.
