NBomber Studio 0.8.2

· 2 min read

NBomber Studio 0.8.2 is out! This is a patch release focused on stability, with a few valuable fixes: Studio can now run fully air-gapped without reaching out to public CDNs, the Active Sessions table no longer gets stuck showing stale rows, and the C# script validator no longer hangs on large build output.

Fixes and improvements​

Air-gapped / offline deployment support​

NBomber Studio's UI used to pull a few assets from public CDNs at runtime: the theme stylesheet, jQuery, jQuery Slimscroll, and the Monaco Editor (used for script editing). That made it impossible to run Studio in fully air-gapped or restricted-network environments.

All of these dependencies are now bundled locally into the build:

  • theme.css is vendored directly into the UI assets instead of being linked from jsDelivr.
  • jQuery / Slimscroll <script> tags removed from index.html.
  • Monaco Editor and its language workers (JSON, CSS, HTML, TypeScript) are now bundled via Vite (monaco-editor + local worker imports) instead of being loaded from a CDN path.

Impact: Studio now works in networks with no outbound internet access.

Active Sessions table not clearing​

Fixed a bug where the "Active Sessions" table would keep showing stale rows after every running session finished — the table never cleared once all sessions left the Active state. The polling logic in ActiveSessionsTable.vue and the backend active/lastupdate endpoint were adjusted so an empty result now correctly refreshes the table instead of being ignored.

ScriptValidator hang on large build output​

The C# script validator could hang indefinitely when a dotnet build produced a large amount of stdout/stderr output — synchronous ReadToEnd() calls on the process streams could deadlock once the OS pipe buffer filled up. Switched to reading stdout/stderr asynchronously (ReadToEndAsync) in parallel with waiting for process exit, eliminating the deadlock.

📦 Docker image & Helm chart​

NBomber Studio is available as a Docker image and a Helm chart for easy deployment:
