Lotus – open-source pricing engine
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…
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.

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…
