Clawdi is a fully managed cloud platform for running AI agents like OpenClaw, Hermes, and Claude Code without any local configuration. Each user gets a sandboxed cloud VM with persistent memory, a browser, file editing, and terminal access — all running inside Phala's confidential compute infrastructure (TEE) for privacy and isolation. The platform decouples agent memory, API keys, skills, and app integrations from the underlying engine, so you can switch frameworks without losing your entire setup. It ships with OAuth integrations for Gmail and Slack, built-in cron job scheduling, browser automation, and long-term memory. Getting started takes roughly three minutes — no terminal, no YAML, no Docker. Built by Marvin Tong, Maggie Liu, and Xiaolu, Clawdi directly solves the agentic developer's most painful friction: rebuilding your setup from scratch every time you try a new agent framework. At $29/month flat, it targets individuals and small teams who want always-on cloud agents without managing infrastructure.

Pretty Fish is a free, open-source Mermaid diagram editor with live preview, 5 built-in themes, multi-page workspaces, and one-click SVG/PNG export. It works offline as a Progressive Web App (PWA) and requires no account, no login, and no installation. It supports all 14+ Mermaid diagram types including flowcharts, sequence diagrams, Gantt charts, entity-relationship diagrams, and Git graphs. The editor includes syntax highlighting, auto-completion, instant error feedback, and a clean split-pane layout. The multi-page workspace lets you manage entire diagram projects in a single session. Export quality is excellent — SVG output is clean and scaling-ready for use in presentations, docs, or design systems. Pretty Fish hit Hacker News front page today with 128 points and has the makings of the go-to Mermaid editor for developers who generate diagrams from AI-assisted documentation workflows. With LLMs increasingly generating Mermaid syntax in their outputs, having a polished renderer and editor matters more than ever.

Reviewer scorecard

This is the 'it just works' solution I've been wanting for months. Spinning up a persistent OpenClaw instance in the cloud without touching config files is genuinely liberating — and the Phala TEE backing means my API keys aren't just floating in someone's S3 bucket.

80/100 · ship

The official Mermaid live editor is clunky and slow. Pretty Fish loads instantly, works offline, and the multi-page workspace means I can manage all my architecture diagrams in one place. Bookmarking this immediately as my default Mermaid editor.

Skeptic
45/100 · skip

At $29/month you're paying for a single managed agent VM, which is expensive compared to just renting a small VPS and running it yourself. The lock-in to their specific supported frameworks (OpenClaw, Hermes, Claude Code) will bite you the moment you want something they don't support yet.

45/100 · skip

It's a genuinely nice editor but it's solving a niche problem — most devs who need Mermaid diagrams already use VS Code extensions or embed them in Notion. And with no backend, there's no collaboration or sharing story, which limits its use in team workflows.

Futurist
80/100 · ship

Clawdi is a prototype of what 'personal AI infrastructure' looks like when it matures. Persistent memory + always-on agents + confidential compute is a legitimate architectural unlock — the TEE angle alone makes this interesting for privacy-sensitive enterprise use cases.

80/100 · ship

As AI tools increasingly output Mermaid syntax to explain architectures and flows, the need for a great rendering environment grows. Pretty Fish positions itself at the intersection of AI-generated diagrams and human editing — that's a well-timed niche.

Creator
80/100 · ship

For non-technical creators who want an agent that remembers context, stays online, and connects to Gmail and Slack without requiring a DevOps background, this hits a real gap. The three-minute setup promise is the key feature for this audience.

80/100 · ship

Five beautiful themes and clean SVG exports mean I can finally use Mermaid diagrams in client-facing presentations without them looking like developer scratch notes. This is the Mermaid editor I've always wanted and the zero-friction setup seals it.
