24 alternatives to Flexprice: Open-Source Usage-Based Billing Toolkit
Hey HN, I’am Koshima, co-founder of Flexprice (https://flexprice.io/). Flexprice is an open source monetization platform for AI & Agentic companies. You can build usage-based, credit-based, or hybrid pricing models with full control. Usage-based billing works on paper, but breaks fast in production: (1) High-volume data (e.g., 10k API calls/sec from AI inferences) breaks naive pipelines, dropping events and causing underbilling or customer complaints. (2) Backfilling missing events or retroactive discounts screws up invoices, forcing 3 AM log stitching to avoid revenue…

Flexprice▲240Hi HN, We're building flexprice, a monetization platform that helps making usage-based, credit based and hybrid pricing easier and We recently added a managed-storage option to the S3 export system in Flexprice. Originally, S3 exports required the usual setup: your own bucket, IAM policy, access keys, region config, and ongoing credential management. That works if you already have infra in place, but it adds a lot of overhead for teams that just want recurring exports for invoices, events, or credit reports. Now there are two options: - bring your own S3 bucket - use a Flexprice-managed S3…

Credyt▲100Hey HN! I'm the founder of Credyt (https://credyt.ai). If you're running an AI product that burns $0.50+ per interaction, you need to bill customers as usage happens, not at the end of the month. Otherwise you're a bank for your customers, and you'll run out of money before they do. Why invoice-based billing doesn't work for AI: Most usage-based billing tools (Stripe Billing, Orb, etc.) were built for SaaS. They meter usage all month, then send an invoice. That works fine when your COGS is 5%. It's a disaster when you're paying your AI vendor upfront for every request and your…

Autumn▲719If you’re on tech twitter you may have noticed an increasing dissent with Stripe and it’s DX. t3.gg (Theo) summarizes it best: “IMO, the biggest issue with Stripe is the "split brain" it inherently introduces to your code base. When a customer checks out, the "state of the purchase" is in Stripe. You're then expected to track the purchase in your own database via webhooks. There are over 258 event types. It's far too easy to have a payment be failed in stripe and "subscribed" in your app.” We've built an OSS abstraction to build any pricing model 1 line of code. The idea is a layer over…

Hi HN, We just shipped a Nomod integration in Flexprice. For context, flexprice is an open-source billing system that handles invoices, usage, and credit wallets. One gap we wanted to close was supporting region-specific payment providers without breaking billing state. With this integration: - Invoices finalized in Flexprice can be synced to Nomod - A hosted Nomod payment link is generated for the invoice - Payment status updates flow back into Flexprice - Invoices and payment records stay in sync - Credits (if applicable) are applied only after payment succeeds This keeps billing logic…

Hi HN! We’re building an open-source pricing & packaging engine for SaaS with a built-in billing system. (https://github.com/uselotus/lotus). We strongly believe pricing is the largest untapped growth lever for SaaS, primarily because pricing affects so many critical systems that don’t talk to each other (billing, payments, feature limits, metering, and CRM). We’re building this infrastructure to fix this and enable quick experimentation. Lotus acts as a central repository for all of your pricing plans and utilizes your payment gateway, to manage usage-based, per-seat,…

Hey HN! We discovered that no one innovates on pricing because every billing software is inflexible. Excited to share our progress with Lotus entering beta (full MIT license, https://github.com/uselotus/lotus). New features: * backtest and run analysis comparing multiple plans * version pricing plans like you version code * Meter and aggregate usage flexibly with custom SQL * billing for usage-based pricing, hybrid, bespoke contracts * generate invoice pdfs or integrate with Stripe, Braintree, Netsuite, Salesforce * webhooks to send alerts when usage thresholds are high…

Hey HN: I'm Kaveh, the founder of Usage (https://www.usage.ai/) We help companies drive down AWS costs. Why? Because the way it's done now is a pain. Stakeholders, especially engineers, are required to spend unnecessary time manually finding underutilized or overly expensive EC2s. We believe the optimization process should be done automatically through a series of sophisticated algorithms. At the moment, there are over 70,000 AWS EC2 prices - doing that manually just won't scale at most organizations. My background is in software engineering. Previous to founding Usage, I…

I'm a solopreneur and I made it very easy to integrate a credit system into your apps and games using Creduse. I built Creduse because more and more users want pay-as-you-go models, and founders need new ways to increase user engagement or nicely limit cost-intensive features (see AI). Creduse is built by a developer for developers. I hope it will help as many startups as possible. Feedback are very much appreciated. Francesco
