Pick your tools and see if they fit together before you write code.
Browse 290+ developer tools, get real-time stack recommendations, and build visual diagrams of your tech stack.
Builder works on desktop only — on mobile, browse tools and learning resources.
Visual Stack Builder
Draw your tech stack as a diagram, from scratch or from a predefined stack, or let the recommendation engine propose one to start from.
- A free Sandbox canvas with no restrictions, plus questionnaire-based recommendations to start from
- Frames, notes, connectors and custom tools show how your stack fits together
- Swap tools and explore alternatives instantly
- Real-time hints on tool relationships and conflicts
- Export your stack as JSON and import it later
Featured Tools
Python
Python is a high-level, interpreted, dynamically typed programming language emphasising readability and simplicity. It dominates data science, machine learning, and general-purpose scripting.
Svelte
Svelte is a compiler-based frontend framework that converts declarative component code into efficient vanilla JavaScript at build time, eliminating the virtual DOM entirely. Svelte 5 introduced runes — a fine-grained reactivity system — alongside SvelteKit as its official full-stack meta-framework.
PostgreSQL
PostgreSQL is a free, open-source object-relational database known for reliability, standards compliance, and extensibility, with rich data types, JSONB, and a large ecosystem of extensions such as PostGIS and pgvector.
FastAPI
FastAPI is a modern Python framework for building APIs from standard type hints, with automatic OpenAPI documentation, Pydantic validation, and native async support.
Mistral
Europe's leading open-weight LLM family, from small edge models to a frontier MoE flagship, available through Mistral's API, its Vibe assistant, the major clouds, or self-hosted.
Grafana
Grafana is the leading open-source platform for composable observability and data visualization, enabling teams to query, visualize, and alert on metrics, logs, and traces from any data source.
Docker
Container platform for packaging applications and their dependencies into portable images that run the same on a laptop, in CI, and in production, with Docker Desktop, Compose, and Docker Hub.
PyTorch
PyTorch is the leading open-source deep learning framework, providing dynamic computation graphs, GPU-accelerated tensor operations, and a rich ecosystem for building and deploying neural networks.

No-Code Builders vs AI Builders: Which One Is Right for You?
Two paradigms for building without traditional coding. Understanding what sets them apart — and when each one wins.
When to Pair Supabase with a Backend Framework
Supabase is pitched as a backend replacement — but for lightweight frameworks like Flask or FastAPI, it works just as well as a managed data layer. Here's why the combination makes sense.
What Is a Tech Stack?
A tech stack is the combination of technologies a project is built with. Here is what that means in practice, the different types, and how tools are organized within one.
How to Choose a Tech Stack in 2026
AI coding tools changed the game, but the underlying technology decisions are still yours to make. Here's how to navigate the options.
