easy-html-deploy

Deploy a single self-contained HTML page to htmlcode.fun for instant sharing. Alias of html-deploy, updated for required descriptions, versioned updates, manual-like preservation, and safe unlocked-version edits.

Alias note: easy-html-deploy is maintained as a compatibility alias of html-deploy. Prefer html-deploy for new installs, but this alias carries the same current htmlcode.fun workflow.

HTML Instant Deploy

Overview

Use htmlcode.fun when the deliverable is one standalone HTML document and speed matters more than full project hosting. The service is an open HTML app marketplace: agents deploy or revise HTML, users can manually like a version in the web UI, and liked versions become preserved immutable snapshots.

Live guide:

• https://www.htmlcode.fun/s/htmlcode-fun-guide

Bundled script:

• scripts/htmlcode_deploy.py for deploy, version append, version inspection, content fetch, and unlocked-version edits.

Decision rule

Use this skill when:

• The deliverable is a single HTML page.
• The page can be self-contained or nearly self-contained.
• Fast sharing matters more than custom domains, CI/CD, or multi-file assets.

Do not use this skill when:

• The project is a React, Vue, Next, or multi-file frontend app.
• The site needs build steps, environment variables, server logic, or asset pipelines.
• The user specifically needs their own domain or production-grade hosting.
• The HTML payload is likely to exceed about 1 MB.

Current htmlcode.fun rules

• Always use JSON; never use multipart/form-data or curl -F.
• description is required: one concise sentence, max 240 characters.
• One request deploys one HTML document only.
• Stable projects should use enableCustomCode=true + customCode.
• For recurring or iterative work, append a new version with createVersion=true instead of creating daily/random short codes.
• A version with likeCount > 0 is locked and must not be overwritten or deleted.
• An unlocked version (likeCount == 0) may be overwritten or unpublished when appropriate.
• Agents must not call like endpoints. Likes are intentionally user/manual actions in the htmlcode.fun web UI.
• After deploy, tell the user the returned url, detailUrl, and/or versionUrl, plus the returned preserveHint when present.
• Successful deploys have a global cooldown of about 10 seconds. On 429, respect retryAfterSeconds.

Recommended workflows

New one-off page

1. Produce a complete HTML document with <title>, viewport, and useful metadata.
2. Deploy with POST /api/deploy and a required description.
3. Return the live link and tell the user they can open the detail page and manually like the current version to preserve it.

Script:

bash

python scripts/htmlcode_deploy.py deploy page.html --title "Launch Page" --description "A concise one-sentence summary of this HTML page."

Stable short link or recurring project

Use a stable customCode; append new versions for future updates.

bash

python scripts/htmlcode_deploy.py deploy page.html --code ai-daily --title "AI Daily 2026-05-08" --description "Daily AI briefing for 2026-05-08."
python scripts/htmlcode_deploy.py append ai-daily page.html --title "AI Daily 2026-05-09" --description "Daily AI briefing for 2026-05-09."

Inspect or reuse an app

bash

python scripts/htmlcode_deploy.py versions ai-daily
python scripts/htmlcode_deploy.py get ai-daily --version 3 --output ai-daily-v3.html

By default, get --output writes the HTML content field to the file. Use --download only when you explicitly want the server's raw download response.

Fix an existing version

Before overwriting, inspect versions. Only overwrite if the target version has likeCount == 0. If it has likes, append a new version instead.

bash

python scripts/htmlcode_deploy.py versions landing-demo
python scripts/htmlcode_deploy.py overwrite landing-demo 2 fixed.html --description "Fixes layout issues in version 2."

The script also performs this likeCount check automatically before overwrite, status, and delete-version.

Publish or unpublish one version

bash

python scripts/htmlcode_deploy.py status landing-demo 2 inactive
python scripts/htmlcode_deploy.py status landing-demo 2 active

Raw API map

• POST /api/deploy — deploy a new app or append a version with createVersion=true.
• GET /api/deploy/content?code={code}&version={version} — read metadata and source.
• GET /api/deploys/{code}/versions — list version history and likeCount.
• PATCH /api/deploys/{code}/versions/{version} — overwrite or set status for an unlocked version.
• DELETE /api/deploys/{code}/versions/{version} — delete one unlocked version. Treat deletion as sensitive; ask first unless the user explicitly requested it.
• PATCH /api/deploys/{code}/current — switch the public current version when needed.

Response handling

On success, save and report relevant fields:

• code
• url
• detailUrl
• versionUrl
• versionNumber
• qrCode
• preserveHint

If an API response contains errorCode, hint, detail, stage, requestId, or retryAfterSeconds, use those fields in troubleshooting. For locked-version errors, append a new version instead of trying to overwrite.

Best practices for agents

• Prefer one high-quality deploy over many tiny edits.
• For user-visible pages, include Open Graph tags when sharing matters.
• Keep CSS/JS inline when practical; avoid large base64 images.
• Use meaningful stable codes for recurring content, e.g. ai-daily, not ai-daily-0508.
• If updating an existing code, read versions first and avoid touching liked versions.
• Treat htmlcode.fun as a fast publication channel, not a full static hosting platform.
• Tell the user when Vercel, Netlify, GitHub Pages, or a real app host is a better fit.

Good fit

• Temporary landing pages
• Demo pages
• Shareable documentation pages
• QR-linked event or campaign pages
• AI-generated single-file frontends
• Recurring reports with stable short links and version history

Poor fit

• Multi-page sites with shared assets
• Framework builds
• Large production frontends
• Apps requiring backend auth, databases, or secrets
• Team workflows with preview environments and rollback controls
