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.
More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.
API Evangelist profiles Plakar the way a machine reads it — 2 machine-readable artifacts, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Plakar scores 28.5/100 (emerging), with a separate agent-readiness read of 0/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Plakar
Each block below is one kind of artifact we hold for Plakar. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
Security Posture 2
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
