Everything inside Companion

See every HTTP request in a live timeline view with full headers, body, timing breakdown, and server-side processing details. Filter by status, method, content type, or custom patterns.

Export any selection of requests as a HAR file for sharing with teammates, attaching to bug reports, or importing into other analysis tools. Supports automatic continuous recording.

Compare two responses side-by-side to spot regressions. Diff headers, body content, and timing. Useful for verifying cache behavior or testing config changes before rolling out.

Browse the ISR cache, fragment cache, and tenant-scoped caches in a tree view. Inspect individual entries with their TTL, size, Vary keys, and hit/miss counters.

Purge cache entries by exact key, route pattern, or tag. Preview what will be purged before confirming. Supports batch invalidation across multiple instances simultaneously.

Track hit rate, eviction count, memory usage, and average entry age over time. Identify cold routes that need warming and hot routes where TTLs could be extended.

A structured editor that understands bext's configuration schema. Autocomplete for keys, inline documentation for every field, and type validation as you type.

Validates your configuration against the running bext version's schema before you save. Catches typos, deprecated keys, type mismatches, and conflicting options upfront.

See exactly what changed before pushing a config update. Side-by-side diff with syntax highlighting shows additions, removals, and modifications across the entire file.

View every active topic with subscriber counts, message rates, and retention settings. Create test topics, publish test messages, and verify delivery in real time.

List all active WebSocket and SSE connections with their client info, subscribed topics, connection duration, and bytes transferred. Disconnect individual clients for testing.

Tap into any topic to see messages as they flow through. Filter by content, inspect payload structure, and measure delivery latency from publish to subscriber acknowledgment.

Scaffold new plugins from templates, edit source files, and hot-reload into a running bext instance. See compilation errors and runtime logs in an integrated console.

Write and execute QuickJS scripts against your instance's API without deploying anything. Test request transforms, response filters, and custom middleware logic interactively.

Run the full bext conformance suite against your instance and track your score over time. Identifies misconfigured headers, missing security settings, and performance anti-patterns.

Connect to bext instances behind firewalls or on private networks via SSH tunneling. Companion handles key authentication, port forwarding, and automatic reconnection.

Run Companion without a GUI for scripted workflows. All panels expose a CLI interface — run cache purges, config checks, and conformance audits from shell scripts.

Drop Companion into your GitHub Actions or GitLab CI pipeline. Validate configs before deploy, run conformance gates, and export HAR traces as build artifacts.
