Ship code images.
Not headless Chrome.

A hosted API that renders syntax-highlighted code screenshots — with themes, window decorations, and line numbers — so you never have to run Puppeteer in production.

The problem

Running headless Chrome is painful

Code image generators exist. The hard part isn't the HTML — it's keeping the renderer alive in production.

🥶
Cold starts
Spinning up a Chromium process on every Lambda or Cloud Run invocation adds 3–8 seconds to your pipeline.
🔡
Font hell
Getting monospace fonts to load in a container — with correct ligatures — is a multi-hour distraction you won't miss.
💥
Memory spikes
Chromium is a memory hog. Concurrent screenshot requests OOM your container at the worst possible moment.
🔧
Constant maintenance
Browser updates, sandbox flags, new --args, different behavior across OS versions. None of that is your product.
Use cases

Built for programmatic volume

Not for developers tweeting a snippet — for systems generating images at scale, automatically.

📰
Blog & newsletter pipelines
Auto-generate code images from MDX or Markdown at build time. No browser step in your CI, no Lambda layer to maintain.
🎓
Developer education platforms
Render lesson code snippets as polished images with correct themes and decorations, at the moment a course is published.
📚
Docs & changelog generators
Embed beautiful code previews directly in generated documentation without coupling your docs build to a headless browser.
🤖
AI content agents
LLM pipelines that produce code need a rendering step. One API call turns the output into a shareable image with no extra infrastructure.
📣
Social media bots
Automated posting pipelines for Twitter/X, LinkedIn, or Mastodon that need visually consistent code images on a schedule.
🖼️
OG image services
Generate open-graph preview images for code-sharing sites, paste tools, or repositories dynamically — no per-request Chrome instance.
Quickstart

One endpoint. One POST.

Send code, get a WebP image back. That's it.

// response is a WebP image buffer
const imageBuffer = await response.arrayBuffer();
fs.writeFileSync("screenshot.webp", Buffer.from(imageBuffer));
import requests

response = requests.post(
    "https://your-api.example.com/screenshot",
