Product Updates - Polymet Docs

Jun 10, 2026

Sharing, redesignedThe share button now sits right next to your collaborators, and on shared projects you can see who’s online at a glance — live presence on every avatar. Open it to see the full member list, invite people, or manage access from one popover. It adapts to how the project is shared: private, invite-only, or open to your whole org.Multiple custom domainsCustom domains went further — you can now connect more than one domain to the same project. Point an apex and a www, or several aliases, all at the same published prototype, with the same guided DNS setup and automatic HTTPS as before.Projects recover themselves when something breaksIf your project’s underlying structure gets corrupted — say from a GitHub sync or an edit gone wrong — Polymet now detects it and rebuilds it automatically instead of leaving you stuck. Even when the structure is missing entirely, it finds your app’s main entry point and renders it, so you’re never staring at a blank canvas.Improvements

Cleaner project settings — more consistent forms and an improved color picker

Bug fixes

Fixed plan upgrades that could create a duplicate subscription or fail outright
Past subscribers can open the billing portal again
AI-generated images now reliably show up in your asset list
A clearer warning when your prompt is too long to generate

May 27, 2026

Sharper, more accurate editsWe studied thousands of real generations and fixed the patterns that tripped the AI up. When you ask for a specific change, it stays in scope instead of rewriting things you didn’t mention. It reuses components you already have instead of duplicating them, and builds pages and their routes together so navigation works the first time.The AI catches its own errors as it buildsWhen the AI changes your project, it now spots any errors its own edits introduced and fixes them on the spot — so you get a working preview instead of a broken one to clean up yourself.Improvements

After you log in, you land back on the page you were trying to open instead of always bouncing to your projects list

Bug fixes

Removing a teammate or revoking an invitation now reliably takes effect everywhere

May 13, 2026

Claude Opus 4.7 with adaptive thinkingPolymet now generates with Claude Opus 4.7. The AI reasons through your request before it builds — and you can watch that thinking stream live in chat. Better output, and you can catch a wrong turn early instead of after the fact.Rollback recommendations when a generation failsWhen a generation hits an error, the chat now points you to specific safe versions to roll back to. One click back to something that works, instead of being stuck.Improvements

Generations that hit the output limit stop cleanly and pre-fill a follow-up prompt, so you continue in one click
The file navigator flags orphaned routes — pages nothing links to — with a one-click fix
The code editor dropped the confusing source/render toggle

Bug fixes

SVG images in prompts show as thumbnails instead of raw markup
Working previews are no longer falsely flagged as blank or broken
“Fix errors” tells you when there’s nothing to fix instead of erroring out
Public prototype links no longer pick up a stray preview token
Generations no longer fail on image-heavy conversations
Fixed a crash when a thread briefly went missing mid-generation

May 2, 2026

Conversation compaction — long chats don’t break anymoreLong projects used to hit the AI’s context limit and just fail. Now the AI automatically summarizes the conversation as it grows and keeps going. Build something big over dozens of turns without hitting a wall — and you still see the full conversation, the summarizing happens behind the scenes.Backend management for everyoneSee, enable, and manage your project’s database, logs, and edge functions right in the app. This used to be locked away — now it’s yours.Persistent preview URLsYour project’s preview URL stays the same across every generation. No more losing your login session, form state, or scroll position every time the AI makes a change. Every past version also gets its own shareable link.Rebuild button on broken previewsWhen a preview fails to load, you get a Rebuild button instead of a dead screen — it re-bundles the broken parts and gets you back to a working preview.Improvements

Full-height chat — the conversation gets the whole left panel
Code view shows your entire project file tree, not just the focused file
The live prototype URL is visible in focus view, one click to open
A fresh look — new orange brand color and a redesigned profile menu
“Rollback and try again” recovery when a generation errors
Untitled projects auto-rename from your first prompt
Faster canvas load for older projects
“Rebundle” is now called “Rebuild” everywhere

Fixed a batch of layout and overflow glitches across the app
Fixed previews getting stuck on a loading screen
A message you sent could show up twice — fixed

Apr 17, 2026

Multi-thread chatProjects now have multiple chat threads. Keep a thread per feature or idea, switch between them, and let each one auto-name itself from your first message. Separate lines of work, one project.Pick your modelA model selector lets you choose which AI generates your code — across multiple providers, from fast lightweight models to flagship ones. Use the right tool for the job.Version cards and rollbackEvery generation shows up as a version card in chat with view, publish, and rollback actions. Roll back code, chat history, or both.The AI remembers your whole projectThe AI can search back through earlier messages — in the current thread or across all of them — and pull back images you shared before. Ask it to do something “like we did in the dashboard thread” and it can actually find it.Improvements

Generations automatically retry with a fallback model when one hits an error
Streaming recovers on its own — reload mid-generation and you land back on the live thread
Visual edits and error fixes show as rich cards in chat
Figma imports show a card with frame thumbnails
Duplicating a project starts with a fresh chat

Apr 3, 2026

Custom domainsConnect your own domain to a published prototype — apex or subdomain. Guided DNS setup, live verification status, automatic HTTPS with nothing to configure. Ship client demos and internal tools under your own brand instead of a preview link.Improvements

The file navigator orders files by type and mutes unused ones
The error fixer dropped noisy routing errors that were more confusing than helpful

Mar 20, 2026

Supabase: give your prototypes a real databaseDescribe the data you want to store in plain English. Polymet provisions a real Postgres database, writes the migrations, sets up security, and wires your app to it — no SQL, no dashboard, no account to manage.Backends: edge functions and full-stack appsPolymet doesn’t just build the screens anymore. The AI writes and deploys real server-side functions — auth, webhooks, scheduled jobs — running on a global edge network. Full-stack apps from a description.Integrations: connect anythingWant payments, email, or SMS in your prototype? Describe it. Polymet detects the integration, asks you for the API key (stored safely as a secret), and wires up the whole flow end to end. Real capabilities, not mock buttons.Improvements

Per-file pricing is cheaper — edits dropped from 10 to 6 credits

Bug fixes

GitHub backup is more reliable across the board
GitHub pushes retry on transient failures instead of just failing
A disconnected GitHub account now clearly shows it needs reconnecting
Your login state holds across generations, so you don’t get logged out every prompt

Mar 6, 2026

GitHub integrationConnect a Polymet project to a GitHub repo and the two stay in sync both ways. The AI commits and pushes as it generates; push changes on GitHub and Polymet pulls them back as a new version. There’s a manual sync button and a clear last-synced status, and if your connection breaks, Polymet tells you.Improvements

The AI’s code edits show a real diff in chat instead of opaque text
Images the AI generates show up directly in chat
The design system tab loads reliably and shows import paths and usage

Bug fixes

Project settings now validates CSS variables before saving
Fixed a batch of design system, project settings, and GitHub sync bugs

Feb 20, 2026

AI skillsThe AI loads task-specific expertise on demand — building charts, working with data, and more — instead of carrying every instruction at once. Sharper, more accurate generations for the task in front of it.Interactive chat toolsThe AI can now ask for your input mid-generation. The first one: it can delete a file, but asks you to confirm first.

Feb 6, 2026

The AI explores your codebase like a developerThe AI can now run real shell commands while it builds — searching your files, inspecting history, tracing how things connect. It makes better-informed edits instead of guessing, which matters most on larger projects.Bug fixes

Your own prompt messages now show up when you open an older version

Jan 23, 2026

Generated apps look right on mobileGenerated apps and previews now scale correctly on phones, instead of rendering at desktop width.Bug fixes

Dec 26, 2025

Every project is git-backedEvery Polymet project now has full version history. Open any past version to see exactly what it looked like, and roll back to it — code, chat, or both. This works on older projects too.Live theme editingChange colors, fonts, radius, and dark/light mode and watch the preview update in real time. Save when it looks right.File rename, delete, and share — rebuiltRenaming, deleting, and sharing files now show you exactly what will change before you confirm, and no longer freeze on large projects.Code export for every projectDownload any project as a complete, ready-to-run codebase — design system included.Improvements

Live error checking in the code editor — syntax and build errors show as you type, and Save is blocked until your code compiles
Versions get descriptive AI-written names instead of generic labels
