24 alternatives to Nomod payment integrated into usage-based billing stack

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…

Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

    Flexprice▲240

    Hi 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…

  3. 3FO

    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…

    Credyt▲100

    Hey 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…

    Hey HN, stripe-no-webhooks is an open-source library that syncs your Stripe payments data to your own Postgres database: https://github.com/pretzelai/stripe-no-webhooks. Here's a demo video: https://youtu.be/cyEgW7wElcs Why is this useful? (1) You don't have to figure out which webhooks you need or write listeners for each one. The library handles all of that. This follows the approach of libraries like dj-stripe in the Django world (https://dj-stripe.dev/). (2) Stripe's API has a 100 rpm rate limit. If you're checking subscription status…
