Side-by-side comparison of AI visibility scores, market position, and capabilities
Zero-code eBPF network tracer giving backend teams full request visibility without instrumentation; YC-backed with 2.5K GitHub stars used by YC companies to reduce incident resolution from months to minutes.
Subtrace is a US-based zero-code network observability platform — backed by Y Combinator — providing backend engineering teams with full request-level visibility into every API call, database query, and service interaction across their infrastructure without requiring code instrumentation, agent installation, or root privileges. Using eBPF (Extended Berkeley Packet Filter) kernel technology, Subtrace captures complete request payloads, latency metrics, HTTP status codes, headers, and correlated logs from the operating system network layer — providing the "inspect element for your infrastructure" that traditional APM tools (Sentry, Datadog, OpenTelemetry) cannot deliver without significant instrumentation investment.
$2.3B raised at $29.3B valuation; $2B+ ARR (Q1 2026); used by 50%+ of Fortune 500. Dominant commercial AI coding tool; built on VSCode fork with native agent mode. Competing with GitHub Copilot, Windsurf, and Lovable in the vibe-coding wave.
