Blueprintr

https://blueprintr.io Blueprintr is a diagram-first knowledgebase for infrastructure and architecture teams. Instead of burying diagrams inside wiki pages, it puts the diagram at the centre and attaches documentation, context and live data to the shapes themselves. The editor, Vellum, ships with AWS, Azure, GCP, network, BPMN and UML libraries, supports custom icon packs, and includes a CLI for validation, rendering and diffing. Vellum AI can generate a diagram from a text prompt, convert a screenshot into an editable diagram, and explain a system through a chat sidebar that draws on the canvas as you ask questions. Strata adds depth. Click a firewall, subnet or service to open runbooks, configuration notes or a nested subdiagram, taking a single blueprint from the high-level view down to incident-level detail. Podium turns a blueprint into a presentation, with frames as slides and tags as chapters, so one diagram can support a design review, customer handover or board update. Continuum connects Blueprintr to your infrastructure. It scans AWS and Azure accounts and draws what it finds, reconciles against Terraform state to show drift directly on the diagram, and on Enterprise plans links shapes to live data from 34 connectors including Datadog, PagerDuty, ServiceNow and CloudWatch. Continuum reflects changes without overwriting your work, so hand-drawn context stays in place. Blueprintr is built for MSPs, MSSPs and enterprise IT teams who need architecture documentation that stays current and is easy to share. Blueprints can be embedded in other sites, published to a custom subdomain, password-protected and sent through a publish-approval workflow. Enterprise customers get SAML SSO, SCIM, IP allowlisting and an optional dedicated single-tenant environment with data residency. Plans start with a free Personal tier offering unlimited public and private blueprints. Premium adds AI features and live collaboration, Team adds Continuum Cloud and shared workspaces, and Enterprise adds live connectors and advanced security controls.
