Vers

Vers is "git for running compute" — a branchable microVM platform from HD Research (hdresearch) that lets you fork a live virtual machine (memory, processes, sockets and all) in roughly 258 microseconds, commit its state as an immutable content-addressable snapshot, and restore or branch that snapshot anywhere. Built for AI agent swarms, parallel scenario and database-state testing, CI preview environments, and time-travel debugging, Vers exposes a 63-operation Orchestrator Control Plane API (OpenAPI 3.1) behind a bearer API key, plus a git-style CLI, official SDKs for nine languages, and two Model Context Protocol servers so coding agents can drive compute directly.

Vers publishes 12 API contracts indexed on the APIs.io network, including Commit Tags API, Commits API, Deploy API, and 9 more. Tagged areas include Company, Compute, Virtualization, MicroVM, and Orchestration.

The Vers catalog on APIs.io includes 1 Spectral governance ruleset.

Vers’ developer surface includes documentation, API reference, getting-started guide, support, engineering blog, signup flow, authentication, and 21 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
Agent Skills (SKILL.md packages)	distribution	19.2 (thin)	-	1
Official SDKs on Packagist, pub.dev and Hex	distribution	19.2 (thin)	-	1

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

Standards implemented 2

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
