Sigasi Studio Talkback

Talkback is a Sigasi Studio service that automatically collects metadata about how Sigasi Studio is used and sends this metadata to Sigasi through a secured connection.

Why should I enable Talkback?

By enabling Talkback you help us improve Sigasi Studio:

  • Talkback lets us determine which features are heavily used. This helps in planning which kind of features are valuable for you as Sigasi Studio user, so that we can adjust our product roadmap.
  • Talkback collects performance statistics, that we can relate to the project sizes. Together with our in-house performance tests, this helps us keep the Sigasi Studio compiler and user interface fast.
  • Talkback helps us reduce software errors by collecting incident reports from a wide range of use cases.
  • The activation of Talkback is required to enable our free educational and open source licenses.
  • Talkback is automatic and less cumbersome than feedback surveys.

The end result is that you can use an always-improving Sigasi Studio.

How does Sigasi use this information

Sigasi uses the information transmitted by Talkback for marketing and product planning and development. We use it for deciding which features to develop and improve, for finding and fixing bugs and for finding and fixing performance issues.

What kind of information is sent through Talkback?

Talkback transmits meta-information about your project, operating system, Java Virtual Machine, tool usage, build performance, system statistics, license type, and incident reports (stack traces) that occur due to software errors. Talkback never transmits any HDL code. All transmissions are through an industry standard SSL secure connection.

In the Talkback transmissions, we identify your Sigasi/Eclipse workspace using a generated identifier (a standard Java universal unique identifier UUID).

Talkback stores all the information it transmits in a local log file, so that you can inspect it. The information is human-readable, in JSON (JavaScript Object Notation) format.

You can access the Talkback log to verify by clicking Window > Preferences > Sigasi > Talkback > Talkback log.

This log file is rotated for each new Sigasi Studio session or when the log reaches a certain size.

How do I enable or disable Talkback?

Talkback is always disabled by default. To enable Talkback, or to disable it later on, do the following.

In Eclipse

Click Window > Preferences > Sigasi > Talkback and select or deselect the checkbox “Enable Talkback”.

In VS Code

Talkback in VS Code only concerns the LSP server process, the client VS Code extension instead uses the Telemetry setting.

  • Press Ctrl+Shift+P to open the Command Palette
  • Select Preferences: Open Settings (UI)
  • In the Setting tab, navigate to Extensions > Sigasi > Enable Talkback
  • Select or deselect the checkbox


The Sigasi Studio for VS Code will collect telemetry data when an error occurs within the extension itself. This is used to fix bugs and help guide the direction of the product. This is aligned with VS Code’s telemetry and can be tweaked using the VS Code setting: telemetry.telemetryLevel. Note that this VS Code setting is on by default.
For more information regarding telemetry refer to VS Code Telemetry.

What about my Firewall or Proxy?

Talkback uses the https protocol to send the information. If your firewall blocks SSL connections Talkback will not be able to send diagnostics. Your firewall should allow outgoing connections to

Talkback does not support Proxies. If Talkback is unable to connect to our server directly because of your firewall or proxy server, you need to purchase a commercial license.

Features like Talkback are against our corporate policy, even if it is disabled. What can I do?
