Last week we published the catalog — every tool we ship, what it does, what it costs. This is the same shelf read from the other end. For each product, the limit comes first: the thing it does not do, the case it is wrong for, the buyer who should close the tab.
That is a strange way to write about your own products, so here is the reasoning. A refund is more expensive than a lost sale — not in money, in trust. Someone who buys the wrong tool, discovers the gap on day three, and asks for their money back has had a bad week because of something we could have told them in one sentence. And a buyer who reads a limit and thinks that's fine, I don't need that is worth more than one who never saw it, because nothing later can surprise them.
Every limit below was read out of the live product this morning, the same way the prices were. Where a tool genuinely has no ceiling worth naming, we say so rather than inventing modesty.
The Developer Labs
Three free, browser-based workspaces. They share one limit, and it is the most important sentence on this page.
Work stays in the tab until you export it or save a named project.
Brand Token Studio, API Contract Lab, Mock Data Lab
The Labs run without an account. There is no autosave and no local draft: close the tab, refresh it, or crash it, and unsaved work is gone. An optional free account lets you save named projects to the Wigley Studios API, with version history, so you can come back tomorrow. Export still hands you a file you own, whether or not you sign in.
If your instinct is to treat a Lab like a document you'll come back to, sign in and save, or use the export button. Closing a tab without either of those is still a way to lose an afternoon.
Until you save, nothing you paste into a Lab reaches us. Saving a named project POSTs that payload to the API under your account. Sketching against real payloads or real brand values can stay on your machine; it does not have to.
The Design Pipeline
It will not invent a look for you, and the free tier is one generation — not one a month.
UI Kit Generator
This is a configuration engine, not a creative partner. You choose a style preset, set colors, radius, and shadows, pick component groups, and it renders a coherent system from those settings. What it will not do is answer the question what should my product look like? — you have to arrive with an answer, or at least a preference. If you are hoping to describe a vibe and receive a design, this is the wrong door.
One more edge worth knowing before you start. Since October 2026 the generator is free with a Wigley Studios account, every preset and export format included, with a ceiling of 50 generations a day; there is no paid tier.
What you see is what ships. There is no generation step.
UI Kit Packs
Packs are finished goods. You are buying a specific, pre-built component set as it appears in the preview — not a starting point that a generator will then tailor to your brand. Anything you want changed, you change yourself in the code after download.
That makes the preview the single most important part of the purchase. If the preview is close but not right, buy the Generator instead and configure it; if the preview is right, a pack is instant. All eight are free with a newsletter signup, as one zip or one kit at a time, so nobody has to choose in advance.
One component at a time, and every attempt spends a credit.
PromptUI
PromptUI builds a single component from a description. It is not a system generator, so asking it for “a design system for a fintech dashboard” is a category error — that request belongs to the Generator. Ask it for one card, one pricing table, one nav bar.
PromptUI was retired in October 2026, once a single prompt to a general model could produce the same page; the section stays for anyone reading what it was. Its credit model was the part people misread: a generation was consumed when it ran, not when you liked the result.
The Backend Pipeline
One-time payments only. Subscription billing is on you.
ShipKit
ShipKit gives you a structured FastAPI application with JWT auth, Stripe Checkout, an admin panel, and MySQL models via SQLAlchemy with Alembic migrations — bought once, owned outright, $29 for Starter and $79 for Professional. What it does not include is subscription billing. Checkout runs in payment mode, for one-time purchases; there is no plan, renewal, proration or failed-payment logic. If you sell monthly plans, budget for adding Stripe Billing yourself.
We would rather say that plainly than let you discover it after launch. (This box used to say ShipKit had no migration tooling, which was true of 1.0; 2.0 ships Alembic with its first revisions written, and our guide to zero-downtime migrations with Alembic applies directly.)
Two smaller edges. It is MySQL — if your team is a Postgres shop, budget for the swap rather than assuming it. And the deploy scripts and CI/CD templates are Professional-tier only, so the $29 Starter is source code you deploy by your own means.
The Standalones
Windows only, and it never touches your cloud library.
PicSift
PicSift is a native Windows desktop application. There is no macOS build, no Linux build, and no web version. This is the limit most likely to catch someone out, because the rest of the page reads like any other software purchase — so if you are on a Mac, stop here.
The second limit follows from the first: it works on files on your machine. It does not connect to Google Photos, iCloud, Dropbox, or any other hosted library, and it does not sync between the PCs you install it on. Pointing it at a folder your cloud client happens to mirror is not the same thing as deduplicating your cloud library, and we would not recommend treating it as such.
Pricing reflects machines, not features: $29 activates one PC with a year of updates, $59 activates as many as you need with lifetime updates, and both include everything.
It writes and schedules. It will never tell you how a post did.
PostPilot
PostPilot generates on-brand posts from a brand profile, lets you review and queue them, and on Unlimited posts them automatically on a schedule. It is a composition and scheduling tool, full stop. There is no analytics side: no impressions, no engagement rate, no best-time-to-post recommendation, no reporting of any kind. If your actual problem is I don't know what's working, PostPilot does not answer that question and is not trying to.
The other boundary is reach. Automatic posting goes to X and only X. Content you generate for anywhere else is yours to copy out and post by hand, which is a perfectly good workflow — just not an automated one.
Free gives you three lifetime preview credits, the one-time $9.99 Starter unlocks 30 generations, and Unlimited is $24.99 a month.
It licenses software you already sell. It does not sell it for you.
Chiave
Chiave is the one B2B product here, and the one most often approached for the wrong job. It generates and validates license keys, manages customers, and keeps audit logs. It is not a storefront, not a payment processor, and not a distribution channel — you still need somewhere to take the money and something to deliver the download. Chiave starts the moment after a sale, not before it.
It is also the lineup's most expensive commitment, and a recurring one: $49.99 a month for Starter and $99.99 a month for Unlimited, with annual billing at $499.99 and $999.99. Every other tool on this page can be bought once or used free; this one cannot, because it runs a live service on your behalf. The 30-day trial requires no credit card, which is the right way to find out whether that trade makes sense for you.
Two Things Not on This Page
We build Shopify apps as well, which run on their own terms and their own store listings rather than as part of this lineup. And Bravura, the Python GUI framework several of these tools descend from, is heritage rather than shelf stock — it is where the lineage starts, not something we would point a new buyer at today. Neither belongs in a fit guide to the current catalog, so neither gets a card here.
How to Use a Page Like This
Read the bold line under each product and nothing else. If none of them disqualify you, the catalog is a better guide than this article — go read the lineup, or the stack guide if you want to see how the pieces fit together. If one of them does disqualify you, we have done our job: you spent four minutes instead of $29 and a support ticket.
The limits above are not roadmap teasers. We are not promising that ShipKit will grow subscription billing or that PicSift will come to macOS. Some of them may change and we update this page when they do (ShipKit's migrations arrived in 2.0, October 2026, and its box changed with them) — but a fit guide that reads as a wish list is worse than no fit guide at all, so everything here describes the software as it exists today, in July 2026, with the ceilings it actually has.
Start Where Nothing Is at Stake
The three Developer Labs are free, need no account, and never see your data. They are the cheapest possible way to find out whether the way we build tools suits the way you work.
