Catch every mistake before you go live.
Test Mode lets you build and break things safely — with fake members and sandbox payments. And the in-browser inspector now triages your whole setup: it points at the exact bad value, suggests the fix, and tracks your go-live readiness as you click through your Webflow site.
Every app starts in Test Mode — free until you launch.

An inspector that does the debugging for you
Open your site in Test Mode and the in-browser inspector audits your Memberstack setup where it actually runs.
Go-live readiness checklist
The new Overview tab triages your setup at a glance and tracks findings across pages as you navigate — so you know exactly what's left before launch.
Diagnostics that name the fix
The inspector points at the exact bad value: it suggests valid plan and price IDs, flags custom-field key typos with a “did you mean…”, and reality-checks your gating.
SDK Methods Explorer
A searchable list of every SDK method with copy-paste snippets and open-in-Playground links. Custom-code sites get this instead of an empty inspector.
Ask Rey handoff
Turn any finding into AI guidance in one click — with SDK-aware tips and per-method Playground links, so the fix is never a docs hunt away.
Safe sandbox testing
Test signups, logins, and payments with test members and test transactions — test and live mode are fully separate environments, so nothing touches your real members.
Renders right on any site
Refreshed theming with dark mode, cleaner badge, and animations — and the inspector is isolated from your site's CSS so it looks right everywhere.
From sandbox to launch day
Test Mode is how confident launches happen.

Build in Test Mode
Every Memberstack app starts in Test Mode. Sign up test members, run test payments, and break things freely — test mode is a separate environment from your live members.

Browse your site with the inspector
Open your Webflow site and the inspector rides along, auditing forms, plans, gating, and attributes on every page you visit.

Fix what it finds
Each finding names the exact value to change and suggests the fix — or hand it to Rey for AI guidance with copy-paste snippets.

Flip to live
When the readiness checklist is green, switch to Live Mode and launch with real members and real payments — no surprises.

Everything you need to know about Memberstack. Can't find what you're looking for? Reach out to our team.
Every Memberstack app starts in Test Mode — a sandbox where you can sign up test members, run test payments, and experiment freely. Test mode and live mode are fully separate environments with separate members and API keys. When you're ready, flip to Live Mode and launch.
As you browse your site in Test Mode, the in-browser inspector audits your Memberstack setup where it runs: signup and login forms, plan and price IDs, custom-field keys, data attributes, and content gating. Findings are tracked across pages in a go-live readiness checklist on the Overview tab.
Very. The inspector points at the exact bad value and suggests the fix — valid plan and price IDs when one doesn't exist, a “did you mean…” for custom-field key typos, and a reality check on gating rules.
Yes. Custom-code and non-attribute sites get the SDK Methods Explorer — a searchable list of every SDK method with copy-paste snippets and open-in-Playground links — instead of an empty inspector.
Any finding can be turned into AI guidance in one click. Rey, Memberstack's AI assistant, picks up the finding with SDK-aware tips and per-method Playground links so you can go from “something's wrong” to a working fix fast.
No. The inspector is isolated from your site's CSS, so it renders consistently on any site — and it ships with refreshed theming, including dark mode.
