🆕 New in v0.126.0 — many agents, one workspace

A workspace is no longer one agent. It is a shelf of them. Keep your coding agent, a research agent, and a book-writing agent side by side in the same project, and switch between them from a rail on the left without losing anything — each one keeps its own conversation, scroll position, and half-typed message while you are away.

┌────┬───────────────────────────────────────────────┐
│ MA │  Chat · Terminal · Files · UI                 │
│ RE │                                               │

└────┴───────────────────────────────────────────────┘

• Each agent is self-contained. Its own sessions, knowledge bases, settings, and browser profile, in its own folder under .thclaws/bots/<name>/. An agent's file tools stop at that folder, so one agent cannot read or write another's work.
• They run side by side. Every agent is its own process, supervised by the app. An agent that crashes is restarted without disturbing the others, and an agent you switch away from keeps working.
• Add an agent from the rail's +. Get any Agent Template from thClaws.cloud, or start a blank agent that behaves exactly like opening a new folder. Up to 8 agents run at once.
• Desktop and browser alike. The same rail works in the desktop app and in thclaws --serve.

Your existing workspaces upgrade themselves. The first time v0.126.0 opens a workspace — in the desktop app or with --serve — it moves your project into .thclaws/bots/main/ (git history included) and tells you it did. Scripts keep working: thclaws -p and --cli at the workspace root step into that first agent automatically. An older thClaws opening an upgraded folder finds a note asking you to update, rather than a broken project.

Before you upgrade: anything that holds your project's old path — an editor window, a script with an absolute path, another clone — needs the new one. Commit or back up first if that matters to you. Your home directory is never upgraded, and hosted workspaces on thClaws.cloud are not migrated by this release.

Highlights

🎨 Media Studio — generate images & video, built in

A point-and-click shell for the new media tools — Text → Image, Image Edit, Text → Video, and Image → Video — across Google Gemini, OpenAI gpt-image-2, Alibaba Qwen, Veo, and DashScope HappyHorse. Pick a provider/model, set the resolution, hit Generate; finished media lands in a live gallery you can click to reuse as the source for the next run. The same tools (TextToImage / ImageToImage / TextToVideo / ImageToVideo / MediaJobStatus) are callable by the agent from chat too — async video included.

🧠 OpenRouter Fusion — many models, one answer

openrouter/fusion fans your question out to a panel of up to 8 models in parallel (each can search the web), then a judge weighs the answers and synthesizes the consensus — multi-model deliberation packaged as a single model id. The new openrouter/fusion+ makes it fully configurable right from the model picker: choose the panel, the judge, the per-model tool-call budget, temperature, reasoning effort, and tool-choice. A practical stand-in when the model you'd reach for isn't available on the platform.

Recently shipped

A release most weeks. Full history in the changelog; the things most likely to matter to you:

• Enterprise policy + client-side audit trail — a signed org policy file turns the same binary into a managed client: branding, an extension allow-list, a forced LLM gateway, OIDC SSO, a forced permission mode, and a payload-free record of every tool call. (ENTERPRISE.md · ภาษาไทย)
• OS-level Bash confinement, on by default — shell commands run inside a kernel-enforced filesystem boundary (macOS Seatbelt, Linux Landlock, bubblewrap fallback), so an obfuscated command still can't write outside the workspace.
• Thai PII masking — an opt-in pipeline that detects and tokenizes Thai personal data before it reaches the model, then restores it in the output.
• Movie Maker — screenplay → shots → generated video, end to end.
• Browser automation — drive a real Chrome session as a tool.
• Workflows — deterministic multi-agent scripts (/workflow run).
• GUI Shells — ship a custom HTML surface with your agent, themed and bridged to sessions, memory and tools.
• thclaws.cloud — an agent catalog, a hosted runtime, and a metered gateway for people who don't want to hold provider keys.
