Do you build custom UIs using React, Vue, or HTML/CSS? Yes. RAX Development designs and builds custom interfaces for FiveM using HTML, CSS, and JavaScript inside NUI (the in-game browser layer). For larger panels — MDTs, business dashboards, multi-step wizards — we also use React or Vue when component structure and state management justify the bundle size.
Quick answer: FiveM UIs = NUI (HTML/CSS/JS). Simple menus: vanilla or ox_lib. Complex UIs: React/Vue + Lua callbacks. Advanced NUI scripts from $99+. Script packages · Describe your UI
What “custom UI” means on FiveM
Players interact with your server through:
- NUI — Full-screen or tablet-style HTML pages (shops, MDT, banking, crafting)
- ox_lib menus / context / input dialogs — lighter UI without a full web page
- Native prompts — Simple text; fine for one field, not for rich layouts
When you ask for React, Vue, or HTML/CSS, you usually mean a custom NUI tied to custom Lua on the client and server.
React vs Vue vs HTML/CSS (how we choose)
| Stack |
Best for |
FiveM notes |
| HTML/CSS/JS (vanilla) | Small shops, status panels, simple forms | Smallest bundle, fastest load, easiest to maintain |
| React | Large MDTs, multi-tab dashboards, heavy state | Build step (Vite/webpack); keep production bundle lean |
| Vue | Step wizards, reactive forms, component libraries | Same NUI rules as React; team preference matters |
| ox_lib UI | Job menus, quick actions, inputs | Not React/Vue — often the right tool instead of NUI |
We pick the simplest stack that meets the design. A flashy React MDT for a 3-button shop is overkill; a vanilla page for a 40-tab police system is painful. You get an honest recommendation in the quote.
How NUI connects to Lua
- Player triggers open UI (command, target, item, zone)
- Client Lua calls
SetNuiFocus(true, true) and sends data with SendNUIMessage
- Your HTML/React/Vue page renders and listens with
window.addEventListener('message', ...)
- UI posts back via
fetch('https://resourceName/callback', ...) registered with RegisterNUICallback
- Client validates, then triggers server events for money/items — never trust NUI alone (secure triggers)
Examples we build
- Police / EMS MDT (records, warrants, bolos)
- Mechanic tablet, tuning, invoice UI
- Gang / business management dashboards
- Custom shop, crafting, and inventory-style panels
- HUD elements and progress overlays (where NUI fits better than scaleform)
- Admin tools (restricted, server-validated)
Styling matches your server brand (dark RP, minimal, etc.). We can align with your Tebex / web presence for a consistent look.
Performance and UX rules
- Keep NUI bundles small — players on weak PCs feel heavy React apps
- Close NUI and release focus when done (
SetNuiFocus(false, false))
- Do not run animations or polling when the UI is hidden
- Optimize images and fonts; avoid huge background videos in NUI
- Test at 1080p and ultrawide; match your community's common resolutions
UI work is tested on staging VPS with real latency, not only on a dev PC.
