7 tools · the Catch, not a ranking
- PolarApache-2.0 merchant-of-record billing for indie and AI products
No first-party CLI in the docs index — SDKs, MCP, and API only. Starter take-rate sits on top of card-brand costs. Polar is MoR, so you do not keep the Stripe account relationship. International cards add extra. Payouts have their own cut.
- Kill BillApache-2.0 in-house subscriptions and payments, no % take-rate
JVM and ops-heavy. Aviate is the proprietary accelerator — not the Apache tree. Self-Hosted OSS Free; AWS Marketplace is ~$40/mo plus the AWS bill. No revenue tiles here because there is no % of revenue to quote.
- KindeHosted auth plus billing, $0 forever, 10,500 MAU, no OSS
Not self-host. Kinde branding stays on Free. SMS is 10 included. Pro is $25/mo to uncap MAU and drop branding. Distinct from Polar (Apache MoR, not an IdP) and Clerk (auth UI, no 0.7% billing take-rate on Free).
- PaymenterMIT hosting billing; self-host free, cloud PaaS $5/mo paid
Vs Kill Bill/Lago/Polar: hosting webshop + provisioning (Pterodactyl/cPanel, WHMCS importer) — not generic subscription metering or Polar MoR. Cloud is $5/mo paid. Self-host is the $0 path.
- AutumnApache-2.0 Stripe billing layer; Free to 8K billing volume
Vs Polar/Lago/OpenMeter: Stripe abstraction + entitlements — not Polar MoR, not Lago/OpenMeter metering-first. Stripe fees still apply. Pro Cloud from $375/mo. Free path is Free tier or self-host.
- Paddle CLIMIT community CLI for full Paddle Billing API; agent-native
Community CLI — not an official Paddle Inc product; API drift risk. Still need a Paddle merchant account (MoR fees apply). Vs Stripe CLI: Paddle-only. Thin MCP forks exist; this is the general CLI.
- Invoice NinjaELv2 source-available invoicing; self-host free, hosted Free 5 clients
LOUD: NOT OSI open source — ELv2 forbids offering it as competing hosted SaaS. Hosted Pro from ~$14/mo (2026 pricing). Vs Lago/Autumn: client invoicing, not usage metering/MoR. Attribution stays unless white-label.
