What is Purchasely?

Purchasely puts its Management API in the terminal and in AI coding agents

Purchasely is an SDK and console for in-app subscriptions and paywalls. Version 6.2 in October let apps send their own business events to trigger campaigns and linked every purchase to the paywall, placement and test that drove it. On November 5 it released a CLI in beta that exposes every Management API operation as a command, shows app metrics in the terminal, and installs a Purchasely plugin into AI coding agents, with dry runs, plan-then-apply and a read-only mode for safe writes.

Firefly III vs Purchasely: editorial side-by-side

F5.0

Firefly III keeps tagging develop builds daily, still with no release notes.

◆ Current state

Firefly III's feed remains automated develop pre-releases. November 12 and 13 added two more develop tags and another boilerplate development release, on top of four on November 12 alone. 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.

Purchasely puts its Management API in the terminal and in AI coding agents

◆ Current state

Purchasely is an SDK and console for in-app subscriptions and paywalls. Version 6.2 in October let apps send their own business events to trigger campaigns and linked every purchase to the paywall, placement and test that drove it. On November 5 it released a CLI in beta that exposes every Management API operation as a command, shows app metrics in the terminal, and installs a Purchasely plugin into AI coding agents, with dry runs, plan-then-apply and a read-only mode for safe writes.

◆ Where it's heading

The SDK releases have steadily moved control of paywalls and campaigns out of app code and into the Console. The CLI moves it again, into scripts, CI and coding agents, with guardrails designed for automated writes.

◆ Prediction

The CLI needs Management API access enabled by Purchasely staff, so the next likely step is broader self-serve access, or more agent-facing tooling built on the same API.
