How this service works
Sort Semantic Versioning 2.0 versions (pre-releases included), give highest and lowest, the bump type between two, and which satisfy an npm-style range (^1.2.0, ~1.2, >=1.0 <2.0, 1.x || 2.x) plus the best match.
Output
Returns a JSON object with: sorted array of all versions (ascending), the largest version string, the smallest version string, an array of stable (non-pre-release) versions, and if a range was provided, the range string, the array of versions that satisfy it, and the single best matching version.
Example use cases
Find latest stable release in list
“I have these package versions: 2.1.0-alpha.1, 2.0.5, 1.9.8, 2.1.0-beta.3, 2.0.0 — sort them and tell me which is the highest stable release.”
Filter versions satisfying npm range
“Which of these versions pass the range >=1.5.0 <2.0.0? Here's my list: 1.4.9, 1.5.0, 1.7.3, 1.9.9-rc.1, 2.0.0, 2.1.0. Also give me the best match.”
Identify pre-release vs stable versions
“Can you sort these semver strings and separate the stable versions from the pre-releases? The list is: 3.0.0-beta.1, 2.9.9, 3.0.0, 2.8.0-alpha.2, 2.8.0.”
Technical details
Endpoint
POSThttps://api.vextorium.com/v1/semver-compare?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need server-side semver sorting, filtering, or range matching without bundling a semver library — especially useful in agent pipelines that need to determine the latest compatible release from a list of versions, or validate which versions satisfy a given dependency constraint. Ideal for CI/CD automation, dependency resolution, and release management workflows.
Side effects
- Empty or missing versions array returns an error
- Invalid semver strings (e.g. 'v1.a.b') may be rejected or cause unexpected ordering
- Malformed npm range syntax returns an error or no matches
- Providing more than 500 versions exceeds the limit
- Pre-release ordering edge cases may differ from client-side semver libraries
