Hey Product Hunt 👋

I'm Manish, founder of @Flexprice . After spending over couple of years building billing systems, I’ve felt this pain deeply: building products is getting easier, but charging for them is still hard.

Modern AI and API-first products need usage-based pricing, credit systems, free tiers, and feature access but implementing all of that feels like starting a second startup just to manage billing 😅.

We tried everything like Stripe Billing, Chargebee, and a few newer tools but none truly solved our needs beyond basic subscriptions. Eventually, we built our own billing system from scratch. It took us over 6 months and still felt like a never-ending cycle of bugs and edge cases.

Every developer or founder I’ve spoken to who deals with anything usage-based had a similar story

@Flexprice is an open-source billing and metering infrastructure built specifically for today’s AI and API-first products. You send your app’s usage events (API calls, GPU time, etc.) and @Flexprice takes care of🧑‍💻

Usage metering
Calculating charges or credit consumption

Billing is such a tricky beast - especially when you're trying to offer flexibility without drowning in complexity. This really resonates. The fact that Flexprice is open-source and handles usage, credits, feature access, and invoicing all in one place? That’s a game-changer.

You can tell this was built from firsthand frustration - it shows in the clarity of the solution.

Excited to see how this evolves. Congrats on the launch, Manish!

@ambika_vaish Thanks for the support 🚀

@ambika_vaish thanks for your support :)

@manish_choudhary19 @ambika_vaish Thanks Ambika! Indeed - we have felt those frustrations ourselves and it drives us everyday to make sure no other builder feels it.

@manish_choudhary19 @nikhil_mishra7 Honestly, that is the best kind of motivation. When something comes from “I’ve been there” moments, it just hits different.

Cheering you on as you keep pushing this forward!

@manish_choudhary19 all the best to you, Manish. For those who are on a hunt on PH for great products, I have only heard good things about working with Manish, how he thinks about products, and you will see that first-hand as his customer. Give him and Flexprice a chance the next time you need to measure billing.

Thanks for the kind words @sandeeptalukdar. Your support means a lot❤️

@slei_orionarm thanks for sharing this with your coworkers. Would love to hear their feedback :)

This is a brilliant example of a product that effectively solves a complex problem something only a few have managed to crack. Leveraging AI in this way is a smart and an impactful choice. Huge kudos to the team on a successful launch!

@puneet_mahey For sure, that has been the thesis of us building flexprice. Thanks for the support❤️

@puneet_mahey thank you so much for your support :)

Who are your current customers/users? :)

Hey @busmark_w_nika we are working with AI agentic and Infrastructure companies to solve for usage based billing use case.

@manish_choudhary19 It would be great to see some companies. :) I think it is a good social proof.
