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
Feature access management
Generating accurate invoices

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.

Looks awesome, really well-polished it seems. I'm a big fan of Resend / Linear, seems like you took a page from their playbook and made this product super accessible for devs and I love it. Definitely solves a pain point that all builders have had. Is it mainly built for indie hackers?
Flexprice
@sebastian_thunman Thanks, Sebastian! 🙌 You're spot on - we're huge fans of tools like Resend, Linear, and PostHog, and have actively used them while building Flexprice.
Our goal is to create something that's genuinely dev-friendly, especially for lean teams where engineers are empowered to solve complex challenges 💪
We fundamentally see billing and AI agent monetization as a product engineering challenge - and that’s why Flexprice is designed to be developer-first and open source 🛠️✨
Flexprice
@sebastian_thunman all the best for your launch!

Congratulations on the launch @Flexprice!
Can you talk about what the open source version has to offer, how it differs from the managed version?
Flexprice
Hey @abhishek_arora4 our open-source version is designed to make it super easy (and free!) for indie hackers, early-stage teams, or developers to quickly integrate metering, billing, and basic pricing workflows into their products.
The managed cloud version builds on that by offering advanced workflows (like automated credit top-ups, custom payment rules), scalability to handle large volumes, built-in security, compliance (ISO, SOC2), and role-based access controls out of the box - basically everything you'd want as your product and customer base grow.

Congrats on the launch @koshima_satija @manish_choudhary19 @nikhil_mishra7 .
Looks really useful for tacking billing issues that devs face. As someone building an AI app that has usage based overhead (token usage), this can be a lifesaver.
Flexprice
@ashitvora Thanks for your support, clearly this becomes all the more grave when it comes to monetizing next billion AI agents!!

@manish_choudhary19 true.
