Runs real statistical and causal analysis locally instead of letting an LLM guess, citing every result to its source. Built for technical users via its MCP server and Python SDK.
FreeWorks offlineOpen source
What to know▼
How it works
Runs 24+ research-grade quantitative methods locally on a dataset you drop in — anomaly detection, causality, regime detection, forecasts — with every finding cited to the method and source behind it. Includes an MCP server and Python SDK for AI agents to call it for verified math.
What's different
Computes real statistics locally instead of having an LLM guess at numbers, with a "0 fabricated" indicator guaranteeing no invented figures.
Pricing
Open source, Apache 2.0.
Best for
Developers and technical users who need verified quantitative analysis, including AI agents that call it programmatically.

Generates a 3D model from a single image entirely on-device using WebGPU, with no server uploads or accounts needed — an open-source tool for developers experimenting with local image-to-3D generation.
Works offlineData stays with youOpen source
What to know▼
How it works
Generates a 3D model from a single image entirely on-device using WebGPU compute in the browser, with no server uploads or accounts.
What's different
Open source and runs locally via WebGPU rather than requiring cloud GPU processing, also deployable on Vercel for instant testing.
Best for
Developers experimenting with local, private image-to-3D generation.

A QR-code digital tip jar that lets live performers collect card and digital wallet tips directly into their own Stripe account, shown on a live on-stage display.
No sign-upOpen source
What to know▼
How it works
A QR code lets audiences send card and digital wallet tips directly to a performer's own Stripe account, with a live 3D jar display showing names and messages on stage.
What's different
No platform cut, no signup, open source, and keys never leave the device.

A macOS Quick Look and desktop viewer for molecular file formats like PDB and SDF, with built-in 3D and cheminformatics tools. Aimed at computational chemists doing research, not general software developers.
Works offlineOpen source
What to know▼
How it works
Adds Finder Quick Look previews on macOS for molecular file formats (PDB, mmCIF, SDF, MOL, XYZ) — press Space to preview — plus a desktop app with Mol* 3D viewing, RDKit grids and Ketcher for computational chemistry workflows.
What's different
Integrates directly into macOS Finder's Quick Look instead of requiring a separate viewer app to open each file.
Best for
Computational chemists doing research, not general software developers.

An open-source SDK that serves weather, ocean and elevation data as map tiles with values baked into the pixels, so you can restyle colormaps or switch to contours client-side without refetching. For developers.
FreeOpen source
What to know▼
How it works
Serves weather, ocean and elevation data as map tiles with the physical values baked directly into the pixels and decoded on the GPU, so you can change colormaps, switch to wind streamlines or contours, or re-scale client-side without refetching.
What's different
One open-source SDK works across MapLibre, Mapbox, Leaflet, OpenLayers, deck.gl and React, and the tile format is documented so you can decode it yourself without being locked to their renderer.
Pricing
Transparent pricing with a free tier.
Best for
Developers building map-based visualizations of weather, ocean or elevation data.

An open-source 20-billion-parameter image generation model from Alibaba with strong Chinese and English text rendering — for developers and researchers building on top of it, not an end-user app.
FreeOpen source
What to know▼
How it works
An open-source 20-billion-parameter image generation model from Alibaba's Tongyi Qianwen team, with commercial-grade text rendering in both Chinese and English.
What's different
Leads in nine benchmark tests and offers strong bilingual (Chinese/English) text rendering in generated images, and is free and open-source.
Pricing
Free to use.
Best for
Developers and researchers building on top of an open-source image generation model rather than end users looking for a finished app.

A free, open-source, browser-based node editor for building procedural 2D/3D geometry with SDFs instead of polygon meshes, exporting to GLSL, PNG or STL — no install needed.
FreeNothing to installOpen source
What to know▼
How it works
A browser-based node editor for building procedural 2D/3D geometry from primitives, transforms and smooth boolean operations, rendered as CPU contours, GPU GLSL, or ray-marched scenes.
What's different
Uses SDFs instead of polygon meshes — you compose mathematical operations rather than editing vertices.
Pricing
Free and open source, no installation required.
Best for
Developers and designers building procedural geometry for shaders or 3D printing.

An open-source React library of prebuilt cinematic section transitions for building scroll-driven landing pages, instead of hand-building Framer Motion animations.
Open source
What to know▼
How it works
Provides 60+ prebuilt React section transitions with a one-command CLI installer, built on Framer Motion.
Best for
Developers building scroll-driven landing pages, portfolios, or storytelling sites.

Open source
What to know▼
How it works
An open-source Markdown extension (fenced ```mdma``` blocks) that lets LLM output render as interactive UI — forms, tables, approval gates, charts, callouts, webhooks — instead of plain text. Ships component renderers for React and React Native, a validator, prompt packs for OpenAI/Anthropic/Google/xAI, a CLI, and an MCP server.
What's different
Deterministic parsing with a headless runtime that includes an audit log and PII redaction.
Pricing
Open source, MIT license.
Best for
Developers building chat interfaces who want LLMs to output structured, renderable UI components rather than plain text.

How it works
An open-source GitHub Copilot plugin that turns visual reference images into quality-gated, procedural Three.js models and deterministic asset families, validating references and preserving hierarchy, sockets and colliders through locked visual passes.
What's different
Curates broadly separated asset concepts ("Sculpt DNA") instead of generating random near-duplicate variations.
Pricing
Open-source.
Best for
Developers building 3D or game content in Three.js who need consistent families of procedural assets.
