Diji — the joyful coding agent
An open coding agent by Dejoiy. Works with every major AI provider and any open-source model, writes real files with a live preview, follows 28 built-in skills, and drives its own cloud browser.
Live: diji-pi.vercel.app · Deploy your own on Vercel · Run the server on Oracle Cloud (free)
What it does
- Any model, your key. Bring your own key for OpenAI, Anthropic Claude, Google Gemini, Groq, OpenRouter, Mistral, DeepSeek, xAI Grok, Together, Cerebras and Hugging Face, or plug in any OpenAI- or Anthropic-compatible endpoint (Muse, Azure, Fireworks, your company's model). Self-hosted open models via Ollama, LM Studio, vLLM or llama.cpp. Diji Free works with no key at all. "Fetch models" lists whatever the provider offers today.
- A real coding agent loop. Diji writes complete files into a workspace, sees the current files on every turn, and edits by rewriting them. Tool calls are plain-text tags, so the agent works even on models without native function calling.
- Ship to your own GitHub and Vercel. Add a GitHub token and a Vercel token in Settings → GitHub & Vercel, then push the workspace to a new or existing repo in one commit, or deploy it live to your Vercel account, straight from the workspace panel.
- Live preview + code + ZIP. Multi-file web apps run instantly in a sandboxed preview (local CSS/JS inlined), open in a new tab, or download as a ZIP.
- Its own cloud browser. Diji ships with a built-in Chromium in the cloud (an Oracle Always Free VM behind Diji's
/api/browser proxy), so every visitor can search the web, read docs and click, type and scroll a real page from the panel with nothing to set up. Run your own private one with one command if you like.
- 28 skills. Playbooks for frontend design, minimalist/brutalist/brand-style UI, redesigns, responsive layouts, motion, Three.js, lazy-senior-dev coding, full output, debugging, code review, React/Next.js, backend APIs, databases, testing with Playwright, security, performance, accessibility, deploying to Vercel/Oracle/AWS, git, docs, charts, PDF/Word/Excel/PowerPoint, Python automation, AI apps, DSA interview prep and video prompts. Diji auto-picks up to three per message, you can pin your favourites, and you can import any open-source
SKILL.md by link or paste.
- Notifications. Toasts, a notification center, and system notifications when Diji finishes while you are in another tab.
- Every screen. Built and tested from 320px phones to 1440px+ desktops, light and dark, keyboard and screen-reader friendly, reduced-motion aware.
- Private by design. Chats, files and keys stay in your browser. Keys only travel inside the request to the provider they belong to, through a stateless proxy that never logs them.
Vibe-coding features
Inspired by the best open-source builders (bolt.diy, Dyad, Cline) and built natively into Diji:
| Feature | What it does |
|---|
| Build / Plan / Ask modes | Plan thinks it through with no file changes, then Build it in one click; Ask explains without touching code (Cline plan/act). |
| Checkpoints & History | Every change is a version with per-file +/− stats. Restore any version, or undo one reply from the chat (Cline, bolt.diy). |
| Diff view & review mode | See exactly what changed in a file; optionally approve or reject each change before it lands (Cline approvals). |
| Fix with Diji | The live preview catches runtime errors and failed loads; one click sends them to Diji to fix (Dyad). |
| Select element | Click any element in the preview and tell Diji what to change about it (Dyad). |
| Images & mockups | Paste or attach screenshots and sketches; vision models rebuild them (bolt.diy). |
| Voice prompting | Talk to Diji with the mic button (bolt.diy). |
| Prompt enhancer | Turns a rough idea into a detailed build prompt (bolt.diy). |
| Templates | Start from React, Tailwind, Three.js, dashboard, portfolio or game starters (bolt.diy, Dyad). |
| @mentions | @file.js pulls a workspace file into the message; @https://… reads a page with the cloud browser first. |
| Project rules | Global rules in Settings plus .dijirules, AGENTS.md, .clinerules or .cursorrules in the workspace (Cline). |
| File locks | Lock a file and Diji will never change it (bolt.diy). |
| Code editor & search | Edit any file by hand (Ctrl+S saves a checkpoint) and search across all files (bolt.diy). |
| Import from GitHub | Bring a public (or, with a token, private) repo into a chat (bolt.diy git clone). |
| Open in StackBlitz | Run full Node/npm projects (Vite, Next.js…) in the browser for free (bolt.diy runs on the same WebContainer engine). |
