gm legends, happy Thursday.

Here’s today’s developer tool bonanza: built‑in AI that drafts code, tests and docs right in your repo with GitHub Spark; an autonomous engineer that spins your feature specs into working code via Lovable Agent Mode; and a live, clickable map of your codebase courtesy of Naiad Lens.

Buckle up your browser, key in your hotkey, and let’s own today.

P.S. Launching soon? We’d love to hear about it → editorial@producthunt.co 🫶

GitHub Spark turns plain English into a full‑stack app repo with UI, database models, auth, AI endpoints and CI. Tweak layouts in the visual editor or dive into the code—no config required.

🔥 Our Take: Spark spins up a working prototype in under a minute. You get routing, data models and auth wired up automatically, but the generated code often needs cleanup around edge cases and styling. It’s a brilliant shortcut for mockups and internal tools, just don’t skip the review before production.

Lovable Agent Mode turns a plain‑English spec into real code. You ask for a login flow or data API. It breaks the work into steps. It writes the code. It runs tests. It hunts bugs. It pulls in libraries. It summarizes every change. You just review the results.

🔥 Our Take: Seeing AI debug its own code and explain what it did blew my mind. We’ve moved from simple scaffolds to full‑stack assistants that actually close the loop. This is a genuine step change in how we build software.

Naiad Lens scans your repo and turns it into interactive diagrams of architecture, sequence and activity. Click any node and jump right to the exact source line. Save and share so your docs never rot. Works with Java, Kotlin, Python, JavaScript, TypeScript and Go.

🔥 Our Take: When that full‐repo map suddenly appears you stop poking around aimlessly and start fixing the damn bug. It’s the best “holy shit” moment you’ll get in your IDE today.

Aaron asked “Got any prompt recipes that take you from boilerplate all the way to production?” Replies fired off some clever hacks: Gabe crafts a phased‑README then feeds it back to Cursor for a to‑do list, Steve brain‑dumps rough drafts into Grok 4, lets it grill him with follow‑ups, then drops the refined prompt into Claude Code or Windsurf, and Frederik swears by spawning fresh chats whenever context overload torpedoes your flow.

So what’s your secret sauce for prompts that not only start strong but actually ship?
