HeroUI Chat on the edge

HeroUI Chat now starts generation on the edge, streams earlier, and serves previews without a sandbox boot. Reloads and temporary connection drops no longer interrupt an active generation.

The dashboard now has separate HeroUI Pro and HeroUI Chat workspaces. Each product has its own navigation.

AI Chat, rebuilt on the edge

New chats run on a Cloudflare edge runtime powered by Durable Objects. One Durable Object owns each chat's active stream, recovery state, and usage.

The model and tool loop runs on Pi. Pi handles each turn's file reads, edits, and tool calls while HeroUI controls routing, prompts, previews, and billing.

Existing chats stay on the runtime that created them. They keep working without a migration.

Faster starts

Generation opens the stream while the project is prepared. Reconnecting resumes the active stream and its original turn.

Instant previews

Previews now come from immutable static builds. The current preview loads without starting a development server or restoring sandbox dependencies.

Sandboxes still run bounded work such as builds and commands, but they no longer host the preview. When a new build succeeds, the stable preview URL updates immediately. When a build fails, the last working preview remains available.

Generation that recovers

• Resumable streams: Reload the page or reconnect without losing the active generation
• Stalled-turn recovery: Interrupted work resumes from durable state or returns an actionable error
• Bounded tool execution: Commands stop on abort or timeout, with no detached work left running
• Safer billing: Retries reuse the same settlement record, preventing duplicate charges

Edit the theme inside a chat

Open the theme customizer from a chat to adjust colors, typography, radius, borders, shadows, spacing, and component styles. Changes apply to the preview as you work.

Theme editing works for new edge chats and existing chats. When a chat uses a saved Design System, you can sync changes from the builder or edit the chat's copy independently.

Better results while you build

• Preview QA: Chat can inspect the running interface, capture screenshots, and check multi-section pages before finishing
• Version guidance: Generated apps detect HeroUI version drift and offer a guided upgrade path
• Brand details: Generated apps use the project's name and logo for the browser title and favicon
• Image attachments: Pasted and uploaded images use object storage instead of large inline payloads
• Queued prompts: Add a follow-up while generation is running, then send it next or move it to the front
• Completion notifications: Receive a browser notification when a longer generation finishes

HeroUI Pro and HeroUI Chat, separated

A product switcher below the dashboard logo moves between HeroUI Pro and HeroUI Chat.

• HeroUI Pro: Home, usage, Design Systems, docs, and roadmap
• HeroUI Chat: Home, usage, new chat, and recent conversations

Each product opens its own sidebar, keeping chat history separate from package and account navigation.

Platform improvements

• Usage and billing: The usage dashboard separates HeroUI Pro license downloads from HeroUI Chat requests, tokens, credits, and estimated spend. The billing page also shows Stripe credit grants alongside the current plan
• License ownership: Team owners can transfer license ownership to another member from that member's options in the dashboard
• Package delivery: Protected downloads use challenge-response validation, account ban checks, and separate rate limits for interactive CLI use and CI
