Stability release

🔧This release improves Inspectr’s CORS handling.

Changelog

Inspectr

• fix: Handle duplicate CORS headers

Stability release

🔧This release improves Inspectr’s stability, ensuring VPN network changes no longer disrupt the expose tunnel. It also resolves a scrolling issue in the request details view.

Changelog

Inspectr

• fix: Handle expose panic when VPN network changes

Inspectr App

• fix: use ResizeObserver for Request body & Resonse body height

Full Changelog: v1.8.0...v1.8.1

New features

💎 This release delivers a major upgrade focused on stability, performance, streaming reliability of Inspectr Expose, and including some improvements and streamlined behaviour (Copy Curl header sanitisation, UTC times, bundle Monaco Editor, negative rules operators).

The biggest change is a fully reworked Expose Tunnel (V2) with improved behavior for:

• standard request/response
• SSE and HTTP streaming
• long-lived HTTP connections
• chunked transfer encoding
• HTTP upgrade/full-duplex scenarios

✨ The CLI has been improved with better runtime configuration, stronger tunnel resilience (pooling + auto re-register), aligned time format reporting and new rule-engine capabilities with negative operators.

🖥️ The Inspectr App adds better usability improvements, and new workflow features such as enabling Expose directly from Settings and richer operation tooling.

Full Changelog: v1.7.0...v1.8.0

New features

💎 This release improves filtering, automation and ease of usage of Inspectr.

✨ The CLI has been extended to support starting Inspectr with a command and exporting data on exit (see the start command and export docs). The Rules Engine now supports JWT and Base64 decoding, making it easier to detect and inspect encoded values directly in rules (see extracting and decoding values for more details). Ports get automatically assigned when the default ports are already in use.

🖥️ The Inspectr app now keeps filters and sorting on reload, adds MCP filtering options, and introduces a trace timeline filter panel for faster navigation.

New features

feat: Rules

In this release we introduce the Rules Engine, a powerful no-code way to classify, enrich and analyse API requests and webhook events as they flow through Inspectr. With the Rules Engine you can define triggers (e.g., when an operation completes), set matching conditions (path, headers, status, latency, body fields) and attach actions (static or dynamic tags, Git branch, file value, remote lookup) to every matching event.

See the Rules documentation for more details

preview: Trace mode

The new Tracing View brings end-to-end visibility to every request flowing through your system. Inspectr now visualizes each span in a clean, chronological timeline, making it easy to understand service interactions, spot slow components, and follow how tags and metadata evolve along the way. Whether you’re debugging complex chains or validating new deployments, the Tracing View gives you a clear, visual narrative of what really happened behind each request.

Review the Tracing Group docs for more context.

New features

feat: Performance boost

Performance matters, always!

Previously, Inspectr could handle around 15 requests per second, mainly limited by how storage writes were handled in SQLite.
In version 1.3.0, we’ve significantly boosted performance. Inspectr now easily handles 450+ requests per second!

We’ve optimized how storage writes are buffered and processed, making Inspectr much more efficient.
The main performance limit is now your system’s resources, especially the available RAM used for write buffering.
