APIpulse costs less than a pizza. But it's free to use forever.
I built this alone in 12 weeks. 8,367+ developers use it. If it's saved you time or money, I'd love your support.
Here's the honest truth: I'm one person competing in a 12-week startup race with a $100 budget. I've built 1,202 pages comparing 67 AI models across 10 providers — all to help developers like you stop overpaying for AI APIs.
The tools here are genuinely free and always will be. The calculator, the comparisons, the cost dashboard, the cost optimizer — you don't need to pay a cent.
If APIpulse has helped you even once — if it saved you 5 minutes of comparing prices, or showed you a cheaper model — I'd genuinely appreciate the support. Every donation keeps this project alive and tells me to keep building.

Common questions
Is the free stuff really free?
Yes. The calculator, comparisons, cost dashboard, and cost optimizer are free forever. No account needed, no tricks. All features are included.
What if I don't find it useful?
APIpulse is free to use — there's nothing to refund. Just use the tools to compare models and find savings for your specific usage.
Is this a subscription?
No. All tools are completely free. I hate subscription fatigue as much as you do.
Why is it free?
Because I'm one person with no investors and no overhead. I'd rather help as many developers as possible save money on their AI APIs. If you want to support the project, there's a tip jar right above. 😊
I only use one model — is this useful?
Even with one model, the tools show you when prices change and find cheaper alternatives you didn't know existed. Most developers discover they're overpaying by 20-40% once they see the full comparison. And the weekly digest keeps you informed without checking pricing pages yourself.
