Termius

Termius is a modern, cross-platform SSH client for DevOps professionals, network engineers, and infrastructure teams, available on Windows, macOS, Linux, iOS, iPadOS, and Android. It provides secure remote access with encrypted team vaults, shared and synced credentials, SSH keys, snippets, SFTP, port forwarding, jump hosts, and session organization. For programmatic use Termius ships the API Bridge — a self-hosted REST API (OpenAPI 3.0) that encrypts infrastructure data locally and pushes hosts and groups into a Termius Team vault — plus an official command-line client. The company also runs a Security Center with a SOC 2 report.

Termius publishes 2 APIs on the APIs.io network: group API and host API. Tagged areas include Company, Enterprise Saas, SSH, SSH Client, and Terminal.

Termius’ developer surface includes documentation, API reference, getting-started guide, support, engineering blog, pricing, signup flow, and 26 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/termius: open an issue to ask a question, or submit a pull request to add artifacts.
