What is Stellify?

Stellify is an AI-native development platform built around one workflow: connect the editor you already use, let AI wire proven, existing code into your project, and sync the result back to your repository. We call it the Stellify development loop.

The Stellify Development Loop

1. Connect your editor. Claude Code, Cursor, VS Code — any MCP-compatible agent connects to your Stellify project through the MCP server with one config entry and an API token.

2. Find code, don't generate it. Ask for a feature and your agent searches Stellify's curated library first — registration flows, payment integrations, CRUD stacks that already exist and already work. It references what it finds into your project, wires it to your routes and models, and generates only the parts that are genuinely new. Then it verifies: running methods, applying migrations, executing tests.

3. Sync back or export. The assembled feature leaves as standard Laravel — commit it to your GitHub repo with Live Sync, or export the whole project. Your repo stays the source of truth; Stellify is the workbench your code passes through.

Then the next feature: same loop. Every pass through it is code you didn't have to prompt into existence line by line, reviewed once and reused everywhere — we've published a scoped benchmark of what that saves in The Economics of Code Reuse.

What Makes the Loop Possible

Stellify stores code as structured data, not flat files. Files contain methods, methods contain statements, and every unit has a stable identity. That's what lets an agent find a single proven method and wire it in surgically — no syntax errors, no hallucinated glue, no rewriting whole files to change one function.

Beyond the Loop

A full cloud editor — Every project is also editable in the browser: a method-level code editor, a visual Interface Builder with live preview, and a built-in AI chat with the same tools your MCP agent uses. Refine by hand what the agent roughed in.

Import anything — Point the agent at an existing codebase — Laravel, legacy PHP, or another stack entirely — and it rebuilds it in Stellify as structured, editable code.

Work as a team — Invite collaborators with granular permissions. Simultaneous edits are caught at the field level by the edit-conflict system, and branches give you isolated workspaces with entity-level diff and merge.

Feed the loop — Publish your project to Constellation, Stellify's app store, share live pages, or submit your best units to the shared library so other builders can reference them — with attribution preserved through fork lineage.

You Own Your Code

There's a clear separation between Stellify and your business logic. Stellify handles routing, authentication, database connections, asset bundling, and hosting. You write the code that makes your application unique — and it leaves as clean, readable PHP and JavaScript whenever you want it to. No proprietary formats; adoption is reversible by design.

Why This Beats File-Based AI Tools

AI tools like Cursor and Windsurf read your code as plain text. They can't see where one method ends and another begins, or which files depend on each other. So when you ask for a small change, they rewrite entire files — and break things you didn't ask them to touch.

Scoped changes — File-based tools can't prevent collateral damage. Stellify targets specific methods and statements. The blast radius is inherently smaller.

Reuse over regeneration — Structured, addressable code makes a shared library possible: agents reference proven units instead of generating fresh ones. We published a scoped benchmark of the difference in The Economics of Code Reuse.

Concurrent editing — Multiple agents or agent+human editing creates constant merge conflicts in flat files. Stellify's UUID-per-statement architecture handles this natively, with field-level conflict detection when edits genuinely collide.

Verified output — Agents don't just write code here; they run it. Methods execute in a sandboxed environment, migrations apply to your real database, and tests run with automatic rollback — all before you accept a change.

Production-safe output — AI hallucinates bespoke patterns that fail under load. Stellify compiles to standard Laravel — battle-tested framework code.

The Stack

Stellify is built on Laravel, the most popular PHP framework, and produces standard Vue, React, and Svelte components on the frontend.

The backend gives you Laravel's mature, well-documented patterns, and the frontend uses the framework conventions you already know.

What's on the Roadmap

Because code is stored relationally, we can keep building features that are impossible with flat files:

Impact analysis — Before an edit happens, see exactly what it affects. "If you change this method, these 4 views and 2 API endpoints are affected."

Visual change summaries — See what AI changed in plain English, not a wall of diff text.

Statement-level rollback — Undo what AI did to one function without reverting the whole file.

Multi-agent orchestration — Multiple agents working on the same app, coordinated by structure so they don't step on each other.

Confidence scoring — Flag risky edits before they happen. "This touches your payment flow — want a human review?"
