PlacePack is a free browser-based tool and REST API for generating bulk placeholder image packs. Paste a list of dimensions, set colors, and download every image as a ZIP in seconds — no sign-up, no account required.

Unlike Lorem Picsum or random image services, PlacePack generates deterministic, labeled placeholders that never change between renders. This makes them safe to commit to your repo and use in Storybook stories, Playwright visual regression tests, Cypress fixtures, and CI/CD pipelines without flaky diffs.

Key features: • Bulk generation — paste any number of sizes (one per line) and download them all as a single ZIP • Aliases and labels — use syntax like hero:1600x900 or avatar:200x200 to name each image • Retina support — add @2x or @3x multipliers for high-DPI assets • Per-size colors — override background and text color per image with hex values • Color themes — apply branded palettes (Dark, Indigo, Slate, Amber, and more) in one click • Three formats — PNG, SVG, and WebP; switch format globally or per session • 16 presets — Instagram, YouTube, Open Graph, email templates, favicons, responsive web breakpoints, Storybook, and more • Shareable URLs — encode your full configuration in a URL hash and share with teammates • REST API — GET /api/v1/{spec}.{format} for single images, POST /api/v1/pack for ZIP bundles; no authentication required, rate-limited to 30 req/min

PlacePack is used by front-end developers seeding Storybook component libraries, designers filling Figma mockups with correctly-sized placeholders, QA engineers generating stable visual regression baselines, and DevOps teams automating fixture generation in CI without binary files in the repository.

Questions & Answers

As answered by people managing Node.js and PlacePack.top.

What makes your product unique?

PlacePack.top's answer:

Most placeholder image tools give you one image at a time with no context about what it represents. PlacePack is built around bulk generation: you paste a full list of dimensions, name each one with an alias like hero:1600x900 or avatar:200x200, and download the entire set as a ZIP in one click. The images are deterministic, they never change between renders, which makes them safe to commit to a repository and use in automated tests, Storybook stories, and CI/CD pipelines. The REST API extends this to programmatic workflows: a single curl command can generate a full fixture set without any binary files in source control.

Why should a person choose your product over its competitors?

PlacePack.top's answer:

Lorem Picsum and similar services return random photos that change on every request, which is fine for quick mockups but unusable for visual regression testing or anything that needs a stable baseline. Placeholder.com generates images server-side with no bulk workflow, no ZIP download, and no API for programmatic use. PlacePack covers all three gaps: bulk generation, deterministic output, and a REST API. It also goes further with per-size color overrides, retina multipliers, 16 size presets for common platforms (Instagram, YouTube, email, responsive breakpoints), and shareable configuration URLs. Everything runs in the browser with no account required.

How would you describe the primary audience of your product?

PlacePack.top's answer:

Front-end developers and designers who need placeholder images that behave predictably in automated environments. The core users are developers building component libraries in Storybook (where Lorem Picsum causes flaky Chromatic runs), QA engineers setting up visual regression baselines in Playwright or Cypress, and designers filling Figma mockups with correctly-sized, on-brand placeholders before real assets arrive. A secondary audience is DevOps engineers who want to generate test fixture images in CI pipelines without committing binary files to the repository.

What's the story behind your product?

PlacePack.top's answer:

PlacePack started as a fix for a specific frustration: a Storybook setup where components fetched images from Lorem Picsum, causing every Chromatic visual regression run to fail because the images changed. The existing options (random photo services, grey rectangle generators, committing stock photos) all had deal-breaking limitations. The first version was a quick browser tool that generated a ZIP of labeled SVG placeholders from a list of dimensions. It grew from there into a full generator with color theming, presets for common platforms, a REST API, and support for PNG and WebP in addition to SVG.

Which are the primary technologies used for building your product?

PlacePack.top's answer:

React and Vite for the browser-based generator (TypeScript, Tailwind CSS). PNG generation uses the HTML Canvas API on the main thread since Web Workers don't support SVG rasterization, so rasterization stays on the main thread with yielding between items to keep the UI responsive. SVG generation is pure string templating with no external dependencies. The REST API runs on Hono deployed as Vercel serverless functions, with Upstash Redis for rate limiting. WebP is generated via canvas.toBlob. The entire app is pre-rendered to static HTML at build time using renderToStaticMarkup + esbuild for SEO.

Who are some of the biggest customers of your product?

PlacePack.top's answer:

PlacePack is free and doesn't require an account, so there's no customer database. It's used by individual developers, designers, and QA engineers at companies of all sizes, primarily people who find it through searches like "storybook placeholder images", "visual regression test fixtures", or "placeholder image API". If you're using it at your company, we'd love to hear about it.

Node.js mentions (922)

  • What's an event loop anyways?
    Event loops are a paradigm for processing events different than your typical single-threaded or multi-threaded application. Your request gets broken down into async "events" that are executed in a loop to improve performance and minimize synchronization across threads. It is famously used by Node.js as the backbone of their event processing and also by several other technologies like Redis and Nginx. - Source: dev.to / 13 days ago
