Tailscale

Tailscale is a zero-config mesh VPN built on WireGuard that creates secure private networks between devices, users, and services with identity-based access controls, Access Control Lists (ACLs), DNS, and device sharing. Tailscale eliminates traditional VPN complexity with peer-to-peer connectivity and SSO-based authentication. The Tailscale REST API provides programmatic control over tailnets, devices, users, ACLs, and keys using API tokens or OAuth client credentials.

Tailscale publishes 7 APIs on the APIs.io network, including Devices API, DNS API, Invites API, and 4 more. Tagged areas include VPN, Mesh Networking, WireGuard, Zero Trust, and Networking.

Tailscale’s developer surface includes authentication, documentation, pricing, signup flow, GitHub presence, engineering blog, and 7 more developer resources.

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.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/tailscale: open an issue to ask a question, or submit a pull request to add artifacts.
