Questions
4 answersIs DevTool compatible with ESX and QBCore?
Yes - DevTool has been tested with ESX Legacy, QBCore, QBox, and Standalone frameworks. It integrates with your existing resources and common dependencies such as ox_lib and ox_inventory.
How do I install DevTool on my FiveM server?
Download the resource from your Tebex / Keymaster account after purchase, drop the folder into your server's resources directory, add it to server.cfg, then follow the step-by-step guide in our documentation. Discord support is available around the clock.
What is the performance impact of DevTool?
DevTool runs at under 0.03 ms resmon during active gameplay and virtually 0 ms when idle, so it has no measurable impact on server TPS, even at full player capacity.
Does DevTool include lifetime updates?
Yes. Every SleepyCode purchase includes lifetime access and free updates. As FiveM frameworks ship new versions we keep the script compatible.
