Cloudinary is a media platform built around transforming and optimizing images and video on the fly, with a digital asset management layer for teams that handle a lot of media. SteadyLink is file hosting built around one idea: every file keeps a permanent link, and replacing the file publishes a new revision behind that same link. If your main problem is delivering many renditions of images and video, Cloudinary is the more complete tool. If your main problem is updating files of any type without breaking links, SteadyLink is the more direct fit.
Summary
Both services host files and serve them from a CDN. The difference is what each one is designed around.
Cloudinary is designed around media processing. You upload an image or video once and request variations through URL parameters: sizes, crops, formats, quality, effects, overlays, and video operations. Its strengths are the depth of that transformation system and its tooling for media-heavy teams.
SteadyLink is designed around file identity. Each file gets a link based on its ID, such as https://cdn.steadylink.io/a/ASSET_ID. Replacing the file adds a revision, the link starts serving it, and older revisions stay available for rollback or pinned links. It handles PDFs, installers, spreadsheets, and other non-media files the same way it handles images.
Comparison
| SteadyLink | Cloudinary | |
|---|---|---|
| Core focus | Stable links for files that change | Image and video transformation, optimization, and media management |
| File types | Any file type, delivered as-is | Strongest for images and video; other files can be stored |
| Replace a file, keep the link | Built in: dashboard Replace, API, SDKs, CLI | Possible depending on how assets are named and overwritten; check their docs for overwrite and cache invalidation behavior |
| Revision history | Every replacement is kept as a revision, with restore | Varies by plan and setup; check their current docs |
| Pin a specific version | ?v=N serves one revision, cached immutably | Has its own versioning in URLs; check their docs |
| Image transformations | Resize, crop with focal points, convert to WebP, JPEG, or PNG via query parameters | Extensive, including many formats, effects, overlays, and automatic optimization |
| Video processing | Not a focus | A core feature |
| Outside contributors | Replacement requests and request links for uploads you approve | Upload widgets and DAM workflows; check their docs |
| S3-compatible access | Yes, for tools like rclone and the AWS CLI | Check their docs |
| Free tier | Yes, a Free plan | Yes; check their current pricing |
Pricing models differ enough that a direct comparison would mislead. Check SteadyLink pricing and Cloudinary's current pricing page for your own usage.
What Cloudinary does better
- Transformation depth. Cloudinary's URL-based transformation language covers far more than resizing and format conversion, including effects, overlays, text, and fine-grained cropping.
- Automatic optimization. It is known for choosing formats and quality per request to reduce file size. SteadyLink's transformations are explicit, and it does not output AVIF.
- Video. Cloudinary handles video encoding, streaming formats, and video transformations. SteadyLink can convert files between formats as separate jobs, but it is not a video delivery platform.
- Media asset management. For large libraries of brand and product media, with tagging, search, and review workflows, Cloudinary's DAM features go further.
What SteadyLink does better
- Replacing files is the main workflow, not a side effect. Open a file, choose Replace, and the link is unchanged. The same is true from the CLI with
steadylink replace bucket:key ./new-file, and from the API and SDKs. - Any file type. A price list PDF, a desktop installer, a CSV export, and a hero image all get the same stable link and revision history.
- Clear caching after a change. The stable link is cacheable for five minutes, so a replacement reaches viewers within a short, predictable window, while pinned
?v=links are cached for a year and never change. - Rollback without new links. Restoring an older revision makes it current again behind the same address.
- Simple delivery for non-developers. Marketing and operations teams can update a file linked from emails, QR codes, or partner sites without touching code.
Who should pick which
Pick Cloudinary if:
- Your product depends on serving many sizes, crops, and formats of images or video
- You want automatic format and quality optimization per device
- You need video transcoding and streaming
- You manage a large media library with DAM workflows
Pick SteadyLink if:
- The files you publish change, and the links to them must not
- You publish documents, downloads, and other non-media files, not just images
- You want revision history, rollback, and pinned links for every file
- You need basic image resizing and format conversion, not a full media pipeline
Some teams use both: Cloudinary for product imagery inside an app, and SteadyLink for documents and assets that are linked from places that cannot be edited.

Questions
- Is SteadyLink a Cloudinary alternative?
- For some uses. If you need deep image and video transformation, automatic optimization, or video streaming, Cloudinary is the more complete tool. If you need files of any type to keep the same link while you replace them, SteadyLink is the more direct fit.
- Does SteadyLink transform images?
- Yes, with query parameters for width, height, fit, and format. Output formats are WebP, JPEG, and PNG. It is not a full media pipeline like Cloudinary.
- Can I use both?
- Yes. Some teams use Cloudinary for product imagery inside an app and SteadyLink for documents and assets linked from places that cannot be edited.
- How do the prices compare?
- The pricing models differ, so check SteadyLink's pricing page and Cloudinary's current pricing for your own usage.
