Upload each screenshot, promo tile, and description once. We resize and crop every image to the exact spec the Chrome Web Store, Firefox Add-ons, and Edge Add-ons each ask for, hold one copy of your name, summary, and description per store and per language with the character limit checked as you type, and run a pre-submit pass that names every missing or out-of-spec asset before you hit publish.
One library for screenshots, promo tiles, and copy across every extension and the Chrome, Firefox, and Edge stores, with auto-resize per spec, live character-limit checks per store and language, and a pre-submit pass.

Built for these decisions.
If any of these are your question, this is the tool.
How do I stop redoing every screenshot and description nine times?
โ Each asset is uploaded once and resized per store automatically. A screen change flags every listing that uses it, so you update the source and push, instead of hunting through nine forms.
Which listings are out of date after we changed the onboarding screen?
โ The library marks every listing whose screenshots came from the screen you changed. You see the three that need a new export before anyone files a release, not after a user reports a stale image.
Why did Chrome bounce this when Firefox accepted the same upload?
โ The pre-submit pass shows the screenshot was 1280x720, not the 1280x800 Chrome requires, and the summary was four characters over. You fix both before resubmitting and skip a second review cycle.
Did the German description fit, or did it run past the limit?
โ Each language has its own copy with the per-store limit checked live. The German summary that runs long is flagged while you write it, not after it ships truncated to every German user.
Three stores, their own sizes and limits, kept in sync by hand through folders, Figma, and a doc that falls apart by the third extension.
The first extension was fine. You exported a few 1280x800 screenshots, wrote a summary, filled in the Chrome Web Store form, and shipped it. Then you added a second extension, then a third, and you put the same listings on Firefox Add-ons and Edge to reach more users. Now every change is three uploads. Chrome wants a 440x280 promo tile and a 132-character summary. Firefox wants its own screenshot sizes and a longer description field. Edge wants something else again. Your assets live in a folder per extension, the copy lives in a Google Doc, and the source screenshots live in Figma where you re-export by hand every time a screen changes. You tweak one feature, and now nine listings are out of date. You paste a description that was fine on Firefox into Chrome and it gets cut off at the character limit you forgot. You submit, wait two days for review, and the rejection says the screenshot is the wrong dimension. There is no dashboard that holds all of this in one place, which is exactly what a developer asked for in a thread that got no real answer, because the tool does not exist yet.
Four pieces, one tool.
Each piece ships in the first build for waitlist members. SaaS upgrades layer on top.
One library for every extension and store
Upload each screenshot, promo tile, and icon once. Assign it to any extension and any store, and the same source is reused everywhere it appears. When you replace a screen, every listing built from it is marked out of date, so a single product change does not turn into a manual sweep through Chrome, Firefox, and Edge looking for the stale image.

Auto-resize to each store's exact spec
Chrome wants 1280x800 or 640x400 screenshots and a 440x280 promo tile. Firefox Add-ons and Edge Add-ons each have their own sizes. You give us one high-resolution source and we crop and resize to every required dimension, so the design pass happens once and the per-store export stops being your job.

Listing copy per store, per language, limit-checked
The name, summary, and description live in one place, with a column per store and per language. The character limit for each field on each store is checked as you type, so the Chrome 132-character summary is never pasted in from a longer Firefox field and quietly cut off. You see every cell that runs long before any of it ships.

Pre-submit pass that names every problem
Before you publish, one pass per store lists what is missing or wrong: an absent promo tile, a screenshot at the wrong dimension, a field over the limit, a language with no description. You read the list and fix it on your screen, instead of submitting, waiting for review, and reading the same list as a rejection two days later.
Today's tools don't do this.
Every extra extension and every extra store multiplies the same manual work: re-export the screenshots to a new size, re-paste the copy and hope it fits, fill in a third dashboard, submit, and wait. A single rejection for a wrong dimension is a two-day review cycle lost, and a stale screenshot that slips through is a listing your users see before you do. The kit costs $19 a month. One avoided rejection and one afternoon of re-exporting, repeated across a handful of extensions, already costs more than that.
A dashboard where you upload screenshots, promo tiles, and icons once, assign them across your extensions and the Chrome, Firefox, and Edge stores, auto-resize each image to every store's spec, hold listing copy per store and per language with the character limits checked live, and run a pre-submit pass that names every missing or out-of-spec asset.
Direct submission to each store's API so you publish from the dashboard, a diff view that shows exactly what changed between two listing versions, Safari and Opera support, and a shared workspace so a teammate can edit copy while you handle screenshots.
We do not build, sign, or upload the extension code itself, and we do not review or approve your listing. The kit prepares and validates the store assets and copy. You connect your store accounts and click publish.

Solo builder ยท Choppy Toast
This page is a quick vibe-coded probe to test demand and gather feature requests. The actual product, when it ships, will be a polished, hand-built tool, not this scaffold.
For a sense of what "polished and shipped" looks like, here's another product I built: relly.permissionlabs.com.
Honest answers.
Then the page stays live with no expiry. The sooner another developer who is juggling listings across three stores joins, the sooner I build it. Send it to the one who just got a rejection for a wrong screenshot size. That is the engine.
