KeyLines review
A specialized web SDK for exploring and embedding complex connected data.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
KeyLines is a commercial JavaScript SDK for building interactive graph visualization applications on the web. It is designed for developers and analysts working with connected data in areas such as cybersecurity, fraud detection, intelligence, security, supply-chain risk and business intelligence. The toolkit supports interactive views with nodes, links and layouts, and can be embedded in SaaS, on-premise or air-gapped applications. It accepts JSON data and is backend-agnostic, giving teams flexibility over their datastore or data source.
Its feature depth is centered on network exploration. Combo grouping helps reduce visual clutter, while custom styling supports nodes, links, combos and annotations. Graph algorithms include centrality and traversal, and time-bar filtering enables temporal exploration. Event-driven interaction handling supports application-specific behavior, while export to PNG, JPEG, SVG and PDF covers common sharing and reporting needs. WebGL rendering with an HTML5 Canvas fallback addresses different browser and device contexts. TypeScript typing, documentation, demos and a playground are included for development.
The published plans distinguish prototyping, evaluation and production deployment. The 21-day Free Trial includes SDKs, documentation and support from Cambridge Intelligence engineers. The Proof of concept plan adds a playground, support, a commercially agreed evaluation and watermark removal. Subscription is for production deployment and adds the ability to distribute applications to end users, alongside SDKs, the playground and support. Pricing is contact-sales rather than self-serve, and KeyLines is not open source. Choose it when graph structure, temporal analysis and database or framework integration are central requirements; choose a broader visualization tool when the primary need is general-purpose charting rather than connected-data exploration.
