Unified observability, security and incident response for cloud-scale engineering teams
Agents, cloud integrations and OpenTelemetry collectors feed one platform where metrics, distributed traces, profiles and logs can be pivoted between without context switching.
Bits AI, an agent builder and LLM/AI-agent observability help teams triage alerts, explain anomalies and monitor model latency, token spend and agent traces.
Cloud SIEM, cloud security posture management, vulnerability management, workload protection and code scanning correlate threat signals with the telemetry you already collect.
Real user monitoring, session replay, product analytics, synthetic and mobile testing sit alongside CI visibility, test optimization, feature flags and DORA metrics.

The collaborative whiteboard built for product builders
AI Flowcharts, AI Mind Maps and AI Wireframes convert a short text prompt into structured, fully editable diagrams, branched mind maps, or web and mobile wireflows — no manual drawing required.
Boards host diagrams, flowcharts, mind maps, wireframes, embedded media and documents side by side, so a whole product narrative lives in a single shareable file.
Multiple teammates edit the same board simultaneously with live cursors, thread comments attached to specific objects, and mention-based notifications.
Drag-and-drop UI components let teams sketch screens, link them into clickable flows and iterate on product ideas before engineering commits to a build.
Industry standard collaborative whiteboarding with massive template libraries, but less streamlined for rapid AI diagram generation.

Free / Open-sourceCombines mind mapping and project workflows with AI agents, but less focused on pure visual diagramming and wireframes.
Robust collaborative whiteboard with strong AI diagramming tools, but less polished UI wireframing capabilities than Whimsical.

SpecialistSpecializes in tracing and debugging production LLM applications, but does not provide general cloud infrastructure metrics or log management.


Dedicated diagramming platform with strong AI chart generation, but less focus on freeform collaborative brainstorming whiteboards.
SpecialistInstantly turns natural language prompts into mind maps and flowcharts, but offers less freeform canvas drawing flexibility.
Combines whiteboarding and documentation with AI generation, but lacks Whimsical's specialized wireframe shape library.
Exceptional UI wireframing and prototyping tools, but less versatile for general mind mapping and freeform brainstorming.

SpecialistProvides advanced AI-driven threat detection for cloud networks, but focuses purely on security rather than general application performance monitoring.
