Chrome extension for Google Flow

Stop babysitting Google Flow.

Features

A tighter control room for Flow batches.

Stacgen stays focused on the launch-critical workflow: queue work, attach references, reserve quota, and recover when Flow needs attention.

Batch queue control

Paste prompt lines, start a run, and let Stacgen keep image and video outputs moving while Flow asks for only the attention it truly needs.

  • Reserve quota per started output before Flow work begins
  • Keep blocked and failed work separate so resume stays predictable
  • Preview finished outputs before downloading anything

Library Mapper

Turn reusable Flow media into named references and attach them with normal @tags before each output starts.

@product

@scene

  • Import Flow media into a reusable Library
  • Drop normal @tags into prompts with the picker
  • Resolve references server-side before a task starts

Quota-aware automation

Every started output checks the SaaS API first, so free users see clear limits and paid users can keep creating without daily caps.

  • Immediate quota reservation
  • Refunds for non-completed reserved work
  • Dashboard activity history

API-first Flow runs

Generation stays on the production API path, with careful fallbacks for transient Flow errors.

Server-side quota

Free plans are counted per started output. Pro and Lifetime unlock unlimited started outputs.

Manual recovery tools

When Flow asks for attention, Stacgen pauses clearly and keeps enough state to resume safely.

Outputs workspace

Finished images and videos can be inspected first, then downloaded manually or in batches.

Pricing

Simple launch pricing.

The MVP is focused on hard-login, billing, and quota enforcement. Cloud sync, API keys, teams, and AI enhancement are not in this launch scope.

FAQ

Common questions

Do I need Google Flow access?

Yes. Stacgen automates and organizes your existing Google Flow workflow; it does not replace your Google account or Flow access.

What does Pro unlock in the MVP?

Pro removes the daily started-output cap. The MVP intentionally excludes cloud sync, teams, API keys, and AI prompt enhancement until the core billing and extension API are stable.

How does the extension count usage?

The extension checks the SaaS API before starting an output. Free users spend one quota unit per started output; Pro and Lifetime users are unlimited.

What happens when Flow asks for manual attention?

The extension pauses, marks those rows as blocked, and lets you resume them first after you clear the Flow prompt or challenge.

Can I cancel Pro?

Yes. Billing is handled through Stripe, and the dashboard includes a billing portal once you are signed in.

Stop doing it by hand.

Start with the extension, then sign in when you want server-side quota, billing, and unlimited started outputs.
