SnapTiles

About SnapTiles

SnapTiles is a free browser-based 3D building tool that simulates magnetic tile toys like Magna-Tiles. Users drag tiles from a tray and they snap edge-to-edge with a hinge mechanic, while a gravity engine determines whether structures like roofs remain standing. The tool runs without sign-up, works on desktops, iPads, and phones, and includes ready-made builds along with an optional Claude integration that reconstructs tile builds from Instagram or YouTube videos.

Review

SnapTiles translates the physical magnetic tile experience into a straightforward 3D environment. It launched this week and is built by Kalvin Mizzi, who created it to test builds for his 4-year-old son before constructing them with real tiles. The tool is free, requires no account, and runs entirely in the browser using three.js for rendering.

Key Features

• Drag-and-drop tile placement with magnetic snap and hinge behavior that mirrors physical tiles
• Gravity simulation that collapses unsupported structures like roofs that wouldn't hold in real life
• Crash button that knocks down the entire build and a Rebuild button that snaps everything back together
• Ready-made builds under the Ideas section, including a Paw Patrol Lookout Tower
• Claude integration that reconstructs a tile build from a pasted Instagram or YouTube link, running on the user's own Claude account

Pricing and Value

SnapTiles is free with no sign-up required. The Claude-powered video rebuild feature uses your own Claude account, which the maker notes is how the feature stays free. The infrastructure runs on Cloudflare Workers with Durable Objects, D1, and KV, keeping operational costs low enough for a free side project. There are no paid tiers, subscriptions, or in-app purchases mentioned.

Pros

• No account creation or payment needed - the tool loads immediately in a browser
• Simulates real magnetic tile physics including snapping, hinging, and structural collapse
• Works across desktop, iPad, and phone browsers with touch and mouse input
• Ready-made builds give users a starting point without assembling from scratch
• Claude integration extracts tile layouts from social media videos, which is uncommon for this type of tool

Cons

• The Claude video rebuild feature requires a separate Claude account, so users without one can't access that capability
• As a newly launched side project, there may be undiscovered bugs or rough edges across different devices and browsers
• The tool is not well suited for users seeking structured building challenges, tutorials, or guided play patterns - it's an open sandbox with no objectives or progression system

SnapTiles fits well for parents who want to test magnetic tile builds before constructing them physically, or for children who enjoy open-ended 3D building without setup or cleanup. The Claude video rebuild feature adds a practical layer for anyone who follows tile-building content on Instagram or YouTube and wants to replicate those designs. Casual users looking for game-like goals or structured activities won't find those here, as the tool sticks to a simple, unguided sandbox model.
