Open-source pricing and billing engine for SaaS companies to deploy, monitor, and experiment with custom subscriptions and usage-based pricing.
Lotus is an open-source pricing and billing engine that enables SaaS companies to deploy, monitor, and experiment with custom subscriptions and complex models like usage-based pricing. It provides a flexible control panel to integrate data from multiple systems, helping businesses find optimal pricing schemes without significant engineering effort.
SaaS, PaaS, and IaaS companies looking to implement or scale complex pricing models, including usage-based billing, per-seat plans, and enterprise subscriptions.
Developers choose Lotus for its extensible framework, powerful experimentation tools, and seamless integrations, which reduce the time and engineering cost of managing pricing infrastructure compared to building in-house solutions.

Includes backtesting, A/B testing, and forecasting to evaluate pricing changes on business outcomes, enabling data-driven experimentation cycles.
Offers seamless integrations with existing payments and CRM systems, plus an expressive API for custom connections, reducing vendor lock-in.
Simplifies subscription, plan versioning, and deployment tracking for engineering teams, as highlighted in the sensible plan management feature.
Currently only available as a self-hosted solution requiring Docker and maintenance of a complex stack (Postgres, Redis, microservices), increasing operational overhead.
The setup involves multiple technologies like React, Python, Go, and Celery, which can be daunting for teams without diverse technical expertise.
Lack of a cloud-hosted version means teams must handle all infrastructure, monitoring, and scaling themselves, unlike SaaS alternatives.
