Firefly III vs OpenMeter: at a glance
What is Firefly III?
Firefly III keeps tagging develop builds several times a day, still with no release notes.
Firefly III's feed is still automated develop pre-releases. November 14 brought three more develop tags and another boilerplate development release, after five tags on November 12 and two on November 13. None includes a changelog.
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.
Firefly III vs OpenMeter: editorial side-by-side
Firefly III
5.0FINANCE
Firefly III keeps tagging develop builds several times a day, still with no release notes.
◆ Current state
Firefly III's feed is still automated develop pre-releases. November 14 brought three more develop tags and another boilerplate development release, after five tags on November 12 and two on November 13. None includes a changelog.
◆ Where it's heading
The project is in a pre-release stretch where builds ship several times a day without notes. The feed shows activity but not what is changing.
◆ Prediction
The feed does not show what the next stable release will contain; a tagged version with a changelog is the next thing worth watching.
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.
