Changelog

​

Act from your inbox, and a much snappier app

• Answer the agent’s questions straight from email. If the agent asks a clarifying question while you’re away, the email now has one-click answer buttons — tap your choice and the build picks up immediately. Links are signed and safe from email scanners.
• Credits run out mid-build? You get the full picture. The build pauses safely and you receive an email with current progress, screenshots, and the live preview link. Top up and resume where it left off. A “we’ll email you when it’s ready” cue now appears during sprints so you can close the tab with confidence.
• A broad speed pass. The dashboard, opening a project, and chat are all significantly faster, and the hottest screens paint instantly from cache.
• Renaming a project keeps old links working, and builds now survive server restarts and idle timers instead of stalling.

​

Watch the agent think, and dial the effort

• Live thinking ticker. While the agent reasons, its thinking streams in real time; finished reasoning collapses into a “Thoughts” block you can expand later.
• Effort levels. Choose how deep each sprint goes with /effort — low (fast direct pass), medium (task-list loop), or high (full research → code → verify pipeline), with auto routing each sprint for you by default. See Build Modes & Effort.
• Fewer unnecessary questions. The agent now asks clarifying questions only when it genuinely needs an answer — and pings you when a direct sprint finishes.
• Cleaner parallel-agent view with per-branch objective, progress, and conclusion.

​

The terminal-style workspace, on the web

• Terminal chat everywhere. The web workspace now matches the CLI: a terminal-style chat with a / command palette (/sprint, /effort, /model, /balance, /fork, and more) and live view tabs for Plan, Code, and Preview. See The Workspace.
• The pre.dev CLI brings the same agent, slash commands, and views to your terminal.
• Before/after screenshot evidence on every browser verification step — see exactly what the agent checked and what changed.
• Builds pick themselves back up. Interrupted sprints resume automatically instead of waiting for you to notice.

​

Generate media inside your build

• Images, video, audio, and music in chat. Ask the agent for a logo, a hero video, a voiceover, or a soundtrack mid-build — generated media lands directly in your project.
• More reliable builds against your acceptance criteria, with a hardened verification loop.
• Faster, cheaper generated images, and GitHub sync no longer breaks from build cache.

​

2026-06-25

​

Parallel agents you can actually inspect

• The parallel-agent panel shows real work: per-agent live streaming, full tool detail, and real file diffs as multiple agents fan out across a sprint.
• Upgraded coding agent model across all build paths, plus fixes for the agent getting stuck repeating itself.
• Faster app load and a cleaner agent step view with per-step timestamps.

​

​

Usage-based billing for Browser Agents

• Pay per task, not per seat. Browser agent tasks bill against your credit balance — 1 credit = $0.10, with a 0.1-credit floor per task. Failed tasks are free.
• Tier-aware rate limits raise throughput for paid plans.
• Typed billing errors with actionUrl deep-links (see the 2026-04-30 entry) now cover the full task lifecycle.

​

2026-06-09

​

Sessions: fork, merge, and build in parallel

• Run multiple build sessions at once. Fork a session to try something risky, work several in parallel, and merge back what works — merges no longer drop fork edits, even when git is in a bad state.
• OAuth connectors, MCP servers, and agent skills arrive in the coding agent: connect your services once and every build inherits them. See Integrations.
• Secrets and build artifacts now stay strictly out of your GitHub repos.

​

2026-05-26

​

Real-time collaboration and mobile preview

• Multi-session collaboration: live sync, presence avatars, and per-session status across everyone working on a project. Session forks landed earlier in the month and are now hardened.
• Mobile preview with a phone-framed viewport and an Expo QR code for native projects.
• Much faster returns to a project: speculative pre-resume from the dashboard and an instant hot path when nothing changed.

​

2026-05-08

​

Browser agents join the chat

• browser_agent in the workspace: the planning agent can now drive a real browser mid-conversation, with an inline timeline card showing every step.
• Faster and tougher browser automation: an express path for simple extractions, a form-fill specialist, and stronger stealth for protected sites.
• Queue messages while architecture generation is running — they’re picked up the moment it finishes.
