You can't see <em>how</em> the app is structured until you dig through it.</p> <p>So I built <strong><a href="https://github.com/Sumontsc51/Devgri-ai" rel="noopener noreferrer">Devgri AI</a></strong> — you describe an app in plain language and get three panes that stay in sync:</p> <div class="table-wrapper-paragraph"><table> <thead> <tr> <th>Pane</th> <th>What it does</th> </tr> </thead> <tbody> <tr> <td><strong>Chat</strong></td> <td>Describe what you want, in plain language</td> </tr> <tr> <td><strong>Architecture tree</strong></td> <td>The app's structure as an editable node graph — drag, rename, reconnect</td> </tr> <tr> <td><strong>Live preview</strong></td> <td>The generated site renders beside the tree as it changes</td> </tr> </tbody> </table></div> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto/https%3A%2F%2Fdev-to-uploads.s3.us-east-2.amazonaws.com%2Fuploads%2Farticles%2Flveh6hrs7puoioed0y59.gif" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto/https%3A%2F%2Fdev-to-uploads.s3.us-east-2.amazonaws.com%2Fuploads%2Farticles%2Flveh6hrs7puoioed0y59.gif" alt="Devgri AI demo: describe an app, watch the architecture tree and live preview build" width="599" height="337"></a></p> <p>👉 <strong>Live demo:</strong> <a href="https://devgri-ai-olive.vercel.app" rel="noopener noreferrer">https://devgri-ai-olive.vercel.app</a><br> 👉 <strong>Repo:</strong> <a href="https://github.com/Sumontsc51/Devgri-ai" rel="noopener noreferrer">https://github.com/Sumontsc51/Devgri-ai</a></p> <h2> Bring your own key </h2> <p>Devgri is BYOK — your Anthropic, OpenAI or Google key stays in browser memory. PII and token masking runs client-side before anything leaves the tab, and keys are stripped from every payload before a workspace is saved.</p> <h2> Tech stack </h2> <ul> <li>Next.js 14 (App Router) + TypeScript</li> <li>Tailwind CSS</li> <li>React Flow for the architecture canvas</li> <li>Supabase (Auth + Postgres + Row Level Security)</li> <li>Vercel</li> </ul> <p>One thing I like: rules like the trial window and user cap are enforced in <strong>RLS policies</strong>, not just the UI, so the API can't be talked around.</p> <h2> Where I need help </h2> <p>It's an early MVP. It works end to end, but it's rough in places — which is exactly why it's public and MIT licensed. Contributions I'd love:</p> <ul> <li>UX polish on the architecture tree (layout, node editing)</li> <li>Better sync between the tree and the live preview</li> <li>Support for more model providers</li> <li>Tests, docs and bug reports</li> </ul> <p>The repo has a <a href="https://github.com/Sumontsc51/Devgri-ai/blob/main/CONTRIBUTING.md" rel="noopener noreferrer">CONTRIBUTING.md</a>, and getting it running locally takes a few minutes:<br> </p> <div class="highlight js-code-highlight"> <pre class="highlight shell"><code>git clone https://github.com/Sumontsc51/Devgri-ai.git <span class="nb">cd </span>Devgri-ai npm <span class="nb">install cp</span> .env.local.example .env.local <span class="c"># fill in your Supabase values</span> npm run dev </code></pre> </div> <p>If you try it, I'd really like to hear what breaks and whether the architecture-tree idea is useful to you. Issues, PRs and ⭐s all welcome!</p> opensource nextjs ai hacktoberfest
