OG Image Generator on GitHub: What ogimg/ogimg Does and How to Run It

Short answer: ogimg/ogimg is an open-source Next.js project for making branded Open Graph images, the preview graphics that can accompany shared links. You can clone and run its current website locally with Node.js and a package manager. One important limitation: the repository says its landing page is live, but its linked /editor route is not implemented yet. The README describes a planned workflow for choosing a template, customizing it, and exporting a PNG; that workflow is not a currently available editor feature. Check the project README before you build a workflow around it.

What is the OG Image Generator on GitHub?

“OG Image Generator on GitHub” refers to ogimg/ogimg, a repository whose README calls it an open-source Open Graph image generator for brand-consistent link previews. It is source code for a web app, not a packaged desktop utility. Its documented stack is Next.js 16 with the App Router, React 19, TypeScript, Tailwind CSS v4, Radix UI, shadcn/ui, next-themes, motion, and Biome.

That stack tells you what the project is built with; it does not prove that a specific image-generation or rendering pipeline is implemented. The README describes the intended design flow—choose a template, add a title or branding, adjust colors and fonts, and export PNG—but also explicitly says the editor route is coming soon. Treat the repository today as a landing page and a starting point for development, not as a ready-to-use online editor or a documented image-generation API.

Question	Current documented answer
What is it?	Open-source Next.js application source on GitHub.
Can I run it locally?	Yes, using Node.js and a supported package manager.
Can I use the linked editor now?	The README says the editor route is not implemented yet.
Can I self-host it?	The project names Vercel as a deployment target for this standard Next.js app.
What license?	Apache License 2.0; review the license terms for your intended reuse.

Install and run ogimg/ogimg locally

The README lists Node.js 18 or newer, with Node.js 20 or newer recommended, and pnpm, npm, yarn, or bun. It provides clone, install, and development-server commands for pnpm and npm. The following is the documented npm route, which is convenient when npm is already installed with Node.js.

1. Clone the repository

git clone https://github.com/ogimg/ogimg.git
cd ogimg

2. Install dependencies

npm install

Or use pnpm, as shown in the project README:

pnpm install

3. Start the development server

npm run dev

Open http://localhost:3000 in a browser. The command runs the app’s development server. Expect to see the documented landing-page experience; do not expect a working editor merely because the UI links to /editor.

4. Build and start a production version

For a local production build, use the scripts listed in the README:

npm run build
npm run start

The README also documents equivalent pnpm commands, along with Biome lint and formatting scripts:

pnpm build
pnpm start
pnpm lint
pnpm lint:fix
pnpm format

With npm, the corresponding lint and formatting commands are npm run lint, npm run lint:fix, and npm run format. These commands operate on the repository’s current scripts; consult its package.json if the scripts change.

What can you actually do with it today?

The distinction between a project’s goal and its implemented surface area matters if you need an OG image now. The repository describes a product direction: make a branded graphic by selecting a template, changing text and visual styling, and exporting a PNG. But its status note says the editor itself is not implemented. The documented interface is therefore not enough to generate an image through that editor today.

You can still use the repository as a codebase to inspect, learn from, or extend. Its listed structure includes routes and shared styles under app/, UI pieces under components/, constants, utility code, and public assets. If you intend to implement the editor, inspect the actual checked-in source rather than assuming the README’s planned flow is already wired up.

For a production need, first decide whether you want a ready-made editor, a rendering service, or source code to customize. Verify the current repository state and test the complete path you need—including generating the image, retrieving it, and serving it to social crawlers—before switching an existing publishing workflow.

Deploying the project on Vercel

The README identifies Vercel as a deployment target and describes the app as a standard Next.js project. A practical deployment outline is:

1. Fork or otherwise place the repository in a GitHub account you control.
2. Import that repository into a Vercel project using Vercel’s current setup flow.
3. Review the detected framework, build command, and output settings against the repository configuration.
4. Deploy and open the resulting site. Confirm the landing page loads and check the editor route separately; hosting the code does not implement the missing editor.
5. When you change the source, deploy again and verify the updated site.

The project README gives pnpm build or npm run build as the build commands, and pnpm start or npm run start for starting a production server. It does not document a database, image storage service, generation API, or environment variables. Do not invent those as setup requirements; inspect the current source and Vercel build output if your deployment needs more configuration.

Self-hosting this repository gives you control over the web app deployment, but it does not turn the unimplemented editor into a finished product. If your goal is to deliver generated images dynamically, you will need to implement and operate the required rendering and delivery path yourself, or choose a service that already exposes it.

Using the Apache-2.0 source

The repository states that it is licensed under the Apache License 2.0 and links a LICENSE file. Apache-2.0 is a permissive open-source license, but reuse still has license conditions. Read the repository’s license and preserve notices or provide other required material as applicable to your distribution. For legal decisions about a commercial product, consult qualified counsel rather than relying on a short summary.

Choosing a workflow: source, editor, or rendering service

Pick based on what you need to accomplish, not just the label “OG image generator.” The current ogimg/ogimg repository is most directly useful if you want to inspect or extend a Next.js landing-page codebase. If the job is to generate images immediately, confirm that the tool has a working editor or API and that its output format, automation, caching, and deployment model suit your site.

Need	What to check
Use a visual editor now	Can you open the editor, customize a template, and export an image today? The ogimg README says its editor is not implemented.
Build your own generator	Inspect rendering code, supported templates, fonts, assets, and license; the README alone does not document an implemented rendering pipeline.
Automate images for publishing	Check whether there is a documented API, command-line interface, or CI action, and how failures and outputs are handled.
Capture a web page visually	A screenshot service captures a rendered page; that is a different workflow from designing a custom branded social card from title and brand inputs.
Host the application	The README names Vercel; confirm your actual routes and runtime work in your deployment.

Other projects in this space use different approaches. SavvyCal’s open-source og-image documents HTML and CSS templates rendered using Puppeteer-driven headless-browser screenshots, plus caching and Fly deployment; its README lists Elixir, Google Chrome, and Node.js 22.x or newer. OGCOPS describes a client-side Satori rendering approach, a URL API returning 1200×630 PNGs, URL-encoded editor state, and self-hosting on Node.js platforms. These are distinct architectures and requirements; check their own documentation before adopting them.

A third-party GitHub Marketplace action called “Generate OG Image” describes a pull-request workflow that reads Markdown front matter and lets users configure image properties and output paths. Its listing says it is not certified by GitHub and is governed by separate terms. Verify its current status and terms before adding it to a repository workflow.

Or skip the browser setup

If your task is to capture a live web page, ScreenshotNeo is a website screenshot API and MCP server from Yorker Media. It can return a page capture as PNG, JPEG, WebP, or PDF. That differs from generating a custom OG design from a title and brand, but it can help when the required asset is a screenshot of a rendered page.

One GET request is enough to capture a URL. The following cURL, Python, and Node.js examples follow the ScreenshotNeo API documentation pattern; replace the example target as needed.

curl -G "https://api.screenshotneo.com/v1/shot" \
  -d access_key=YOUR_API_KEY \
  --data-urlencode url=https://stripe.com \
  -o shot.webp

import requests

r = requests.get(
    "https://api.screenshotneo.com/v1/shot",
    params={"access_key": "YOUR_API_KEY", "url": "https://stripe.com"},
    timeout=90,
)
open("shot.webp", "wb").write(r.content)

const q = new URLSearchParams({
  access_key: 'YOUR_API_KEY',
  url: 'https://stripe.com'
});
const res = await fetch(`https://api.screenshotneo.com/v1/shot?${q}`);

• Cookie banners, newsletter popups, and chat widgets are removed before the capture; each cleanup step can be disabled.
• Bot checks or CAPTCHAs, blank pages, timeouts, failed loads, and cache hits cost nothing. Response headers identify the page verdict and billing status.
• An MCP server provides take_screenshot, get_page_info, and capture_pdf tools for Claude, Cursor, and other MCP clients.
• The Free plan includes 1,000 screenshots per month without a card; paid plans start at $5 for 3,000 shots. Every feature is on every plan.

Performance, reliability, and cost considerations

For a self-hosted app, performance and operating cost depend on what you deploy and implement. The README provides no benchmark, hosting cost, rendering throughput, or service-level commitment. A landing page build and a high-volume image-rendering service have different resource needs. If you extend the project to render images, measure your own workload, including cold starts, concurrent requests, output size, font loading, and any browser or image-processing processes you add.

Reliability also depends on the complete path. A generated image must be produced correctly, stored or returned, and made accessible to the systems that fetch link previews. Test the actual social-sharing destinations you care about, since an image that appears in a local browser is not proof it is publicly retrievable or cached correctly elsewhere.

Open-source source code may avoid a per-image service fee, but it does not make operation free: compute, storage, bandwidth, engineering, and maintenance can carry costs. A hosted API trades some infrastructure work for usage-based or plan costs. Compare the price with your expected successful captures and the work needed to handle retries, caching, and failed pages. ScreenshotNeo says it bills only clean shots; consult its current pricing and documentation for the plan details and response semantics.

Troubleshooting

Symptom	Likely cause	What to do
git clone is not found	Git is missing or unavailable in the shell.	Install or enable Git, then retry the clone command.
Dependency installation fails	Unsupported Node version, package-manager issue, or dependency resolution error.	Check node --version; use Node.js 20+ as the README recommendation, and retry with the package manager you intend to use.
Port 3000 is already in use	Another process is listening on the development server’s port.	Stop that process or use the development server’s supported port setting, then open the corresponding local address.
The editor route is blank, missing, or unfinished	The repository says /editor is linked but not implemented.	Do not treat this as a setup failure; use the project as source to extend or choose a currently working editor.
Production build fails	Dependency, code, or environment issue in the checked-out revision.	Read the first actionable build error, confirm dependencies installed cleanly, and inspect current package scripts and configuration.
Vercel deployment succeeds but expected image generation is absent	Deployment only hosts the implemented source; it cannot add a rendering feature that is not present.	Verify repository routes and implement or select a real generation path.
Social preview does not show your image	Wrong metadata URL, inaccessible image, or platform-side preview caching can be involved.	Inspect the deployed page’s metadata and image URL, confirm the image is publicly reachable, and refresh the preview using the destination platform’s available tools.

FAQ

Is ogimg/ogimg a working OG image generator I can use in a browser?

The repository’s README says the landing page is live, while the editor route is not implemented yet. It describes the intended workflow, not an editor you can currently rely on.

Can I create an OG image from GitHub Markdown with this project?

The README does not document a Markdown-to-image pipeline or a GitHub Action for this repository. You would need to implement that automation or use a separately documented tool.

Does it support formats other than PNG?

The README’s planned export step names PNG. It does not document support for JPEG, WebP, or other export formats.

Can I use the code in a commercial project?

The repository lists Apache-2.0. Read the license and satisfy its conditions for your use and distribution.

Is it an image screenshot API?

No API is documented in the README. It is a Next.js project repository; a screenshot API captures rendered web pages and is a separate kind of tool.
