Heap’s script won’t slow down your website. Capturing all interactions without degrading performance is as simple as inserting a single line of code into your site header.
If you’re seeing a change in site performance after installing Heap, we recommend you review the installation snippet with your developer. If they’ve customized the snippet in some way, such as stacking API calls, have them update it to be more efficient. See our Install Heap.js guide for guidance on how to optimize the Heap snippet.
If you’re running multiple scripts on your site, we also recommend auditing those scripts for efficiency to improve overall site performance.
For guidance that’s specific to session replay, see Will session replay slow down my site?
