Coding agents that know your stack — instead of starting over every prompt.
Bake your rules in once: language, framework, conventions. Then let the agent auto-route across top code models, show diffs, run security checks and hand you a deployable ZIP — for you, your team or your community.
Generic AI chats forget your rules.
You re-explain everything every prompt.
Stack, framework, naming conventions, security rules — generic AI chats forget them between messages. That costs tokens, time and consistency.
You get code snippets, not a system.
Copy-paste from the chat, assemble files yourself, write the manifest by hand — instead of one finished, coherent resource you can download.
AI code lands in your project unchecked.
No review, no security heuristics, no lint. Duplicate events, unsafe callbacks or missing distance checks only surface when it's too late.
An agent with your rules baked in.
Rules baked in once.
Set language, framework, conventions and a setup skeleton once — every answer follows them. More cost-efficient and more consistent than repeating everything each prompt.
Auto-routing to the best models.
The agent automatically picks a suitable code model across multiple providers — or you pin one yourself. They're the same top models, just with your rules on top.
Multi-stage quality gates.
A deterministic security verifier → automatic repair pass → optional second-model review (critic) and Lua lint. Problems get caught before you ship the code.
Auto-routing across the best code models.
Auto mode picks a suitable code model automatically. Or pin one yourself, depending on your plan:

Anthropic
Claude Sonnet 4.6
Anthropic
GPT-5.5
OpenAI
GPT-5 Codex

Grok Build

From prompt to checked, deployable resource.
Multi-file projects
The agent produces complete resource structures — manifest, server/client logic, NUI and README — as one coherent artifact right in the chat.
Diff view
Change an existing script in the same chat and you see it as a unified diff — you see exactly what's added and removed.
Security verifier + auto-repair
Deterministic checks (anti-dupe, event/callback safety, distance and ownership checks) plus an automatic repair pass when blocking issues appear.
Critic & Lua lint
Optional second-model review for a critical double-check and luacheck linting for clean, runnable Lua — both toggleable per bot.
Live NUI preview
Interactive NUI simulation right in the chat: clickable callbacks, mock data, notify and close behaviour — you see your interface before you ship it.
One-click ZIP download
The finished resource as a ZIP — a ready-to-build base to drop into your project. You adjust config and job names to your own server.
For you, your team or your community.
Solo dev / private
Your personal coding assistant that knows your conventions. Kept private, just for you — no stack setup, no DevOps.
Team
A shared agent with fixed team standards. Access via login or invite code — everyone builds by the same rules.
Community / server owner
A branded coding bot for your community — with its own domain. Optionally monetizable as a Zeptix-first model.
Agency / freelancer
One agent per client with their stack and guidelines. Upload existing resources, audit them and fix them in the same chat.
Same models — minus the repetition.
Rules instead of repetition
You can use the same models directly too — they're the same. The difference: here you bake in rules, knowledge and conventions once instead of retyping them every prompt.
Cheaper, better quality
Less prompt overhead means fewer tokens — and with anchored context plus quality gates the output becomes more consistent and reliable.
Share & monetize
Your agent is a standalone bot with its own URL. Share it with your team or community — or charge credits and turn it into a revenue stream.
velonlabs.dev
velonlabs.dev is a real Zeptix coding bot for FiveM server owners: it builds ESX/QBCore resources with NUI, runs the security verifier and hands out ZIP downloads. The same platform powers your own coding agent.
FAQ about coding agents.
What is a Zeptix coding agent?
A hosted coding bot with its own URL that permanently knows your rules (language, framework, conventions, setup skeleton). It produces coherent multi-file projects as an artifact, shows changes as a diff, checks them with a security verifier and delivers them as a downloadable ZIP.
Which AI models does the coding agent use?
In auto mode the agent automatically routes to a suitable code model across multiple providers. Depending on your plan you can also pin a specific model — including Claude Opus 4.8, Claude Sonnet 4.6, GPT-5.5, GPT-5 Codex and Grok Build.
Which frameworks is this for?
The agent is strongest with FiveM/Lua (ESX and QBCore), with deep ready and security checks plus NUI preview — that's the flagship (see velonlabs.dev). Beyond that you can specify general frameworks like Next.js, React, FastAPI or Express.
Are the generated scripts production-ready out of the box?
They're a ready-to-build, checked base — not a finished production install. You adjust config, job names and integration to your own server. The verifier and optional critic significantly reduce common mistakes, but don't replace your own testing.
Why not just use the model directly?
You can — they're the same models. With the agent you bake in rules and knowledge once instead of repeating them per prompt: lower token cost, more consistent output, plus diff view, security checks, ZIP download and the option to share or monetize the bot.
Where do I create my coding agent?
In the Zeptix Builder on zeptix.dev. Pick bot type "Coding", set language, framework and conventions, optionally upload your own knowledge — and the agent is ready to go.
