Plakar

Plakar is an open-source, end-to-end encrypted, deduplicated backup and restore platform powered by Kloset, an immutable data store engine. It encrypts and deduplicates data at the source before it leaves your system (encryption keys stay in your own secret manager), stores it in a non-proprietary format on S3-compatible, cloud, or local backends, and supports immutable object-lock backups for zero-trust data protection. Plakar ships a CLI and built-in web UI, an official Go SDK (go-kloset-sdk), and a proto3 gRPC connector protocol for building custom importers, exporters, and storage backends. Sources include PostgreSQL, MySQL/MariaDB, Kubernetes, Proxmox, VMware vSphere, S3, SFTP, and many cloud drives. The commercial self-hosted Plakar Control Plane adds organization-wide scheduling, SLA management, and centralized administration. Backed by Seedcamp.

Plakar is profiled on the APIs.io network. Tagged areas include Company, Backup, Data Protection, Disaster Recovery, and Open Source.

Plakar’s developer surface includes engineering blog, documentation, getting-started guide, support, CLI, changelog, and 17 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 could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

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/plakar: open an issue to ask a question, or submit a pull request to add artifacts.

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
Cloud Native (Kubernetes, CNCF, FinOps)	standard	17.2 (thin)	-	-

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 1

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.

tagged — the provider's own APIs.json carries the standard as a tag; implementation not verified
