Lotus – open-source pricing engine

In plain words

Lotus is an open-source pricing engine that handles billing for usage-based, hybrid, and custom pricing models. It lets teams test multiple pricing plans, version pricing changes like code, and meter usage with custom SQL queries. The tool generates invoices and integrates with Stripe, Braintree, NetSuite, and Salesforce, while providing webhooks for usage alerts and analytics on margins and per-customer costs. Released under the MIT license, it addresses inflexibility in traditional billing software.

In the maker’s words, at launch

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…

  Lotus – Open source pricing and packaging infrastructure2022 · github.com · ▲120

  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,…

  Open-source alternative to Stripe Billing and Chargebee

  If 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…

  AI-native billing & payments for usage-based AI products

  CredytNov 2025 · credyt.ai · ▲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…

  Talanoa▲343

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  BBC “In Our Time”, categorised by Dewey Decimal, heavy lifting by GPT▲688

  I'm a big fan of the BBC podcast In Our Time -- and (like most people) I've been playing with the OpenAI APIs. In Our Time has almost 1,000 episodes on everything from Cleopatra to the evolution of teeth to plasma physics, all still available, so it's my starting point to learn about most topics. But it's not well organised. So here are the episodes sorted by library code. It's fun to explore. Web scraping is usually pretty tedious, but I found that I could send the minimised HTML to GPT-3 and get (almost) perfect JSON back: the prompt includes the Typescript definition. At the same time I…
