Adapty vs SolidInvoice: at a glance
What is Adapty?
Adapty lets one paywall flow personalise itself with the app's own user data
Adapty has finished moving customers onto one builder: the old Paywall and Onboarding Builders were deprecated on October 1 and Paywalls now live inside Flows & Paywalls. Since then it added a yearly plan sold as 12 monthly payments on native iOS, and the November 9 roundup brings custom tags, where the app passes a value through the SDK and any text in a flow can display it, alongside flow funnels and screen animations.
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.

Adapty lets one paywall flow personalise itself with the app's own user data
◆ Current state
Adapty has finished moving customers onto one builder: the old Paywall and Onboarding Builders were deprecated on October 1 and Paywalls now live inside Flows & Paywalls. Since then it added a yearly plan sold as 12 monthly payments on native iOS, and the November 9 roundup brings custom tags, where the app passes a value through the SDK and any text in a flow can display it, alongside flow funnels and screen animations.
◆ Where it's heading
With the migration done, the work has moved to making each flow do more: personalised copy, funnel analytics on flows, and animation. Adapty is turning the paywall builder into a general onboarding and conversion surface, with agent-built flows from August and pricing experiments like the 12-payment yearly plan layered on top.
◆ Prediction
Expect more SDK-fed personalisation and per-screen analytics inside flows, and the 12-payment yearly plan to extend beyond native iOS; the entries give no timeline for either.

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.
