info

Softprobe fixes observability’s “missing context” by capturing every user journey as a session graph—making interactions analyzable, automation-ready, and economical to retain.

Problem​

Traditional logs and observability tools center on costly indexing. Teams compensate by sampling heavily, which discards context and slows troubleshooting and support.

Solution​

  • Session Graph: Group events by user session to form one coherent, end-to-end record
  • Cost Restructuring: Replace expensive indexing with session context so 100% of data can be retained and queried more efficiently
  • AI-Ready: Rich session context powers automated root-cause analysis, issue prediction, and smarter support

How it works​

  • Server-Side Collection: A lightweight Wasm plugin in Istio’s Envoy sidecar captures HTTP traffic and business flows, emitting native OpenTelemetry trace data GitHub
  • Client-Side Enrichment: The Web SDK creates sessions spanning multiple traces and adds route changes, performance metrics, and interaction events

Product roadmap​

1. Context View

Visualize end-to-end user journeys as a session graph.

Current

2. ETL

Export and transform session data for downstream analytics and long-term retention.

Next

3. Troubleshooting

Guided workflows for root-cause diagnosis and resolution across services.

Planned
Today

Currently available:

  • Data collection: Web SDK (session-level context) and Wasm plugin on Istio/Envoy producing native OpenTelemetry traces — SP‑Istio Agent is open‑source: github.com/softprobe/sp-istio-wasm
  • Visualization: Context View (session graph across services)
Session Graph in Context View

Current: Context View — session graph across services.

Compatibility & Isolation​

  • Native OTEL compatibility: If your application already uses OpenTelemetry, Softprobe does not interfere and will not modify your application’s OTEL data
Softprobe and user traces are isolated

Softprobe traces and user traces are mutually isolated

Core Outcomes​

Full-context visibility

Capture 100% of interaction details by session, eliminating blind spots caused by sampling.

Cost optimization

Retain full data while reducing overall observability cost.

Kubernetes-Native

Deep integration with Kubernetes/Istio for seamless production deployment.

Zero Code Changes
