Markdown scratchpad
app.unfazed.dev/scratchpad open (opens in new tab)i need a markdown scratchpad: editor on the left, live preview on the right, autosaves to localstorage, word count in the corner. nothing else — no accounts, no cloud. build it and deploy it on unfazed, then send me the link.
I'll build a single-file markdown scratchpad and deploy it on Unfazed. Let me first check the Unfazed deployment contract.
ToolSearch(query: "select:ReadMcpResourceTool,mcp__unfazed_…", max_results: 5)
{
"query": "select:ReadMcpResourceTool,mcp__unfazed__create_workspace,mcp__unfazed__write_workspace_text_file,mcp__unfazed__create_service_deployment,mcp__unfazed__create_static_deployment",
"max_results": 5
}[
{
"type": "tool_reference",
"tool_name": "ReadMcpResourceTool"
},
{
"type": "tool_reference",
"tool_name": "mcp__unfazed__create_workspace"
},
{
"type": "tool_reference",
"tool_name": "mcp__unfazed__write_workspace_text_file"
},
{
"type": "tool_reference",
"tool_name": "mcp__unfazed__create_service_deployment"
},
{
"type": "tool_reference",
"tool_name": "mcp__unfazed__create_static_deployment"
}
]This is a fully client-side app, so a static deployment is the right fit — no server needed. Let me build a self-contained HTML file (with an inline markdown parser so there are no CDN dependencies) and deploy it.

}Done. It's live here:
https://app.unfazed.dev/scratchpad
A single self-contained page — editor on the left, live preview on the right, word count top-right, autosaves to your browser's localStorage ~0.4s after you stop typing (you'll see a brief "saved" flash). No accounts, no cloud, nothing else.
A few details worth knowing:
- Storage is per-browser. Your notes live in this browser's localStorage under one key. Clearing site data or using a different browser/device starts fresh — that's the tradeoff of "no cloud."
- The markdown renderer is hand-rolled and dependency-free (no CDN), so it works offline once loaded and there's no third-party script. It covers the common stuff: headings, bold/italic/strikethrough, inline + fenced code, lists, blockquotes, links, images, tables, and horizontal rules.
- Tab inserts two spaces instead of jumping focus.
- It ships with a short starter note; clear it and it stays cleared.
If you want it to remember notes across devices, that *would* need some kind of cloud sync — say the word and I can add a minimal version (still no accounts, just a shareable URL key), but as asked, this is purely local.
