> Tools to check that ABlyft is loaded, see what the snippet decides, and fix technical problems.



ABlyft ships with several tools for finding problems: a console output (debug mode), simple checks in the browser,
URL parameters for preview and QA, and the Live Log that shows the events your visitors really send.

Start with [Verify the integration](https://docs.ablyft.com/developers/debugging/verify-integration/) if you have just installed the snippet.
Use the other pages when something does not behave as expected.

- [Verify the integration](https://docs.ablyft.com/developers/debugging/verify-integration/): Check in the browser that the snippet is loaded, current and sending events.
- [Preview & Live Log](https://docs.ablyft.com/developers/debugging/preview-and-live-log/): Debug mode, preview mode, QA tool, forcing variations and the Live Log.
- [Common issues](https://docs.ablyft.com/developers/debugging/common-issues/): Snippet not loading, outdated snippet, flicker, consent, JavaScript errors and more.

For a non-technical view on the same problems, see the [Troubleshooting guides](https://docs.ablyft.com/guides/troubleshooting/).
