CLI v1.1.0 Interactive Mode, Webhook Radar & Outpost Scaling - Hookdeck October 2025
Hookdeck's October 2025 updates brought major webhook development improvements. CLI v1.1.0 introduced interactive webhook debugging and session filtering for local development. Hookdeck Radar launched as a free webhook performance monitoring tool. Outpost added GCP Pub/Sub support and Redis Cluster scaling.
CLI v1.1.0: Interactive Debugging and Session Filtering
The biggest workflow improvement this month came with Hookdeck CLI v1.1.0. The release introduces an interactive mode and session filtering that fundamentally changes how you debug webhooks locally.
Instead of constantly switching between your terminal and the Hookdeck dashboard, you can now inspect and replay events directly from your command line. Interactive mode is enabled by default when you run hookdeck listen, providing a rich terminal interface for browsing webhook events, examining payloads, and triggering replays.
The new session filtering lets you focus on exactly the events that matter. Using flags like --filter-body, --filter-headers, and --filter-path, you can isolate specific event types during development.
For example, if you're debugging order issues but Shopify webhooks are sending hundreds of noisy products/update events, you can filter to only receive order creation events:
hookdeck listen 3000 shopify \
--filter-headers '{"x-shopify-topic": "order/create"}'
This is particularly valuable when working with high-volume webhook sources where finding specific test events can be challenging.

Hookdeck Radar: Real-Time Webhook Performance Monitoring
After processing over 100 billion webhooks, we've identified a critical gap: individual developers lack visibility into webhook producer performance.
When webhooks slow down unexpectedly, you're debugging in the dark. Your database looks fine, CPU is normal, logs show nothing unusual, but Shopify webhooks are taking 10 seconds instead of 2. Is it you? Is it Shopify?
Hookdeck Radar solves this by providing a free public dashboard that aggregates anonymized latency data across hundreds of millions of webhooks. You can see real-time performance metrics (p50, p90, p99 percentiles) for major webhook producers like Shopify—no signup required. Subscribe to alerts via email or webhook to get notified when producers experience performance degradation.
Shopify's performance reveals interesting patterns. Average latency (p50) holds steady around 2.5 seconds, while p99 can spike to 15+ seconds during peak periods. When your monitoring matches Radar's metrics, the issue is upstream with the producer. When it exceeds them, investigate your own systems.

Outpost Webhook Infrastructure: Scaling and Reliability Improvements
Outpost saw three releases in October 2025 that significantly expanded its capabilities and improved operational reliability.
The v0.7.0 release leads with GCP Pub/Sub destination support and multi-deployment capabilities. Meanwhile, v0.6.1 and v0.6.0 focused on infrastructure improvements and horizontal scaling with Redis Cluster support.
GCP Pub/Sub Destination Support
The v0.7.0 release adds GCP Pub/Sub destination support, expanding Outpost's ecosystem integration beyond traditional webhook endpoints. Teams using Google Cloud's messaging infrastructure can now receive webhook events through their existing Pub/Sub topics.
Redis Cluster Support
The standout infrastructure improvement came in v0.6.0 with Redis Cluster support. This enables horizontal scaling of Outpost deployments across multiple Redis nodes. For existing deployments, v0.6.0 requires a Redis schema migration to hash-tagged key format. The included outpost migrate tool handles this transition automatically, though teams should plan the migration during maintenance windows.
Workflow Improvements: Slack Integration Updates
Teams using Hookdeck's Slack integration gained a valuable workflow improvement. You can now update issue status directly from Slack notifications. Change issue status to Open, Acknowledged, Resolved, or Ignored without leaving the Slack app.
This seemingly simple improvement eliminates yet another context switch in webhook debugging workflows. When webhook issues are reported in Slack channels, team members can acknowledge and track resolution status without jumping between tools. This keeps the entire incident response process within their primary communication platform.

New Source Types in the Hookdeck Event Gateway
October brought expanded webhook platform support with three new source types, all driven by customer requests:
- Airtable - HMAC signature verification with ASCII input encoding for automation webhooks
- FastSpring - E-commerce platform for digital goods and SaaS with HMAC-SHA256 signature verification
- Ethoca - Mastercard chargeback and fraud prevention with handshake support for custom response handling
Get in touch if you'd like to see support for additional webhook platforms.
That's it for the October 2025 review.
