OpenMeter vs SolidInvoice: at a glance
What is OpenMeter?
OpenMeter rebuilds its API around v3 entitlements, notifications and billing.
OpenMeter is an open-source usage metering and billing engine still on 1.0.0 betas. The September and October betas moved customer entitlements, notification channels and rules, and app actions into a v3 API, while dozens of fixes tightened invoicing, charges and custom-currency billing. Its feed has been quiet since October 9.
What is SolidInvoice?
SolidInvoice 3.1.3 patches payment settling and clears 12 Symfony advisories.
SolidInvoice, the self-hosted invoicing app, is in a patch cycle on 3.1. The 29 October trio brought custom invoice templates, invitation expiry and a fixed upgrade path with migrations at startup or as a Helm pre-upgrade job. 3.1.3 follows with fixes: invoices paid through the API or MCP are only marked paid once the payment settles, the revenue chart counts each month once, and a Symfony bump clears 12 security advisories.
OpenMeter vs SolidInvoice: editorial side-by-side
OpenMeter
0.0FINANCE
OpenMeter rebuilds its API around v3 entitlements, notifications and billing.
◆ Current state
OpenMeter is an open-source usage metering and billing engine still on 1.0.0 betas. The September and October betas moved customer entitlements, notification channels and rules, and app actions into a v3 API, while dozens of fixes tightened invoicing, charges and custom-currency billing. Its feed has been quiet since October 9.
◆ Where it's heading
The work is converging on a stable v3 API for metering, entitlements and invoicing, with custom currencies and credits as the main new billing capability. Deprecating the LLM cost endpoints shows it narrowing to the core billing job rather than chasing AI-specific features.
◆ Prediction
The entries point toward more v3 endpoints going stable ahead of a 1.0 release, but the five-week pause since beta.236 leaves the timing unclear.
SolidInvoice
5.0FINANCE
SolidInvoice 3.1.3 patches payment settling and clears 12 Symfony advisories.
◆ Current state
SolidInvoice, the self-hosted invoicing app, is in a patch cycle on 3.1. The 29 October trio brought custom invoice templates, invitation expiry and a fixed upgrade path with migrations at startup or as a Helm pre-upgrade job. 3.1.3 follows with fixes: invoices paid through the API or MCP are only marked paid once the payment settles, the revenue chart counts each month once, and a Symfony bump clears 12 security advisories.
◆ Where it's heading
After the large 3.0 release in June, work has moved to hardening: upgrade paths, packaging (Snap, static PHP builds) and correctness in payments and reporting. The mention of MCP payments shows AI-agent access is already wired into billing, though the entries don't detail it.
◆ Prediction
Expect more 3.1.x patches on packaging and payment edge cases; the entries don't signal what 3.2 will contain.
