HyperProbe is an AI-native production debugger for investigating live application state without code changes, redeployment, or service restarts. It reads logs and distributed traces, uses a coding agent to locate a suspected file and line, and places a temporary read-only virtual breakpoint there. When the breakpoint fires on live traffic, it captures the variable state asynchronously without pausing requests, then uses the evidence to confirm a root cause. Probes are non-blocking, cannot write memory or execute code, disappear after capture, and are recorded in an immutable audit trail. The service is designed for silent failures, exceptions whose causes occur earlier in the call chain, incorrect behavior without thrown errors, race conditions, third-party contract changes, and business-metric failures. It supports JavaScript, TypeScript, Java, Kotlin, Python, and Ruby, and can run in a managed cloud, self-hosted deployment, or private VPC. The page states that it integrates with PagerDuty, Datadog, Slack, Cursor, Claude Code, Codex, and Opencode, with approval gates and agent-side PII redaction.

OpenAnalytics is an open-source, self-hostable web analytics stack developed by OpenLabs. It uses a lightweight browser tracker without cookies, fingerprinting, or cross-site profiles, and provides aggregate-only analytics for page views, custom events, sessions, web vitals, funnels, retention, embeddable widgets, public sharing, live presence, and Stripe revenue attribution. The repository is a pnpm monorepo comprising a tracker, ingestion collector, queue worker, API, ClickHouse query gateway, realtime SSE service, Next.js dashboard, and CLI. Postgres stores control-plane data, ClickHouse stores events and rollups, and Valkey provides the event queue and realtime cache. The query gateway is the only component permitted to read ClickHouse and verifies Ed25519-signed query envelopes; visitor identity uses a salted hash that rotates nightly, while optional city-level geolocation is resolved against a database on the host. It also includes CSV/JSON import and export, an MCP server, and an AI assistant. The project is licensed under AGPL-3.0. It can be self-hosted with Docker Compose, or used through the authors' hosted instance at getopen.so. Release images are published to GitHub Container Registry.
