Every day I get asked what tools I use to build AI apps and run the channel. Here's everything — the full stack, updated regularly.

Anthropic's agentic coding CLI. Runs in your terminal, edits files autonomously, spawns sub-agents, and maintains memory across sessions. Powered by Claude Opus 4.
AI-native code editor forked from VS Code. Composer mode rewrites multiple files at once. Tab autocomplete predicts your next edit. Pro plan is $20/mo.
OpenAI's cloud coding agent. Runs in a sandboxed container, reads your repo, executes tasks, and submits PRs. Uses GPT-5.3 (codex model). Available in ChatGPT.
Google's open-source coding CLI. Free tier with Gemini 2.5 Pro. Supports tool use, file editing, shell commands. 1M token context window.
The original AI coding assistant. 77M+ developers. Inline completions in VS Code and JetBrains. Copilot Workspace generates full projects from issues. $10/mo.
AI app builder — describe what you want, get a deployed full-stack app with React, Supabase, and auth. No coding required. Free tier available.
The TypeScript toolkit for building AI apps. Unified API across OpenAI, Anthropic, Google. Streaming, tool calling, structured output, multi-step agents. 50K+ GitHub stars.
Anthropic's Python SDK for building production agent systems. Tool use, guardrails, agent handoffs, and orchestration. Released alongside Claude 4.
Most popular LLM framework. 100K+ GitHub stars. Chains, RAG, vector stores, tool use. LangGraph adds stateful multi-agent workflows with cycles and persistence.
Gives AI agents access to 250+ external tools (GitHub, Slack, Gmail, databases) with managed OAuth. Handles the auth and API complexity so your agent doesn't have to.
Lightweight Python framework for multi-agent systems. Agent handoffs, tool use, guardrails, tracing. Successor to the experimental Swarm project.
Deployment platform behind Next.js. Git push to deploy. Edge functions, image optimization, analytics. Free tier is generous. This site runs on Vercel.
Reactive backend — database, server functions, real-time sync, cron jobs, file storage. All TypeScript. This site's backend (courses, videos, user data) runs on Convex.
CDN, DNS, DDoS protection, and edge computing. Free tier handles most needs. This site uses Cloudflare for DNS and analytics. Workers for edge compute.
Drop-in auth for React/Next.js. Pre-built sign-in UI, session management, user profiles, org management. This site uses Clerk for authentication.
Local-first markdown knowledge base with wikilinks. My entire DevDigest pipeline lives here — research, scripts, content calendar, daily journal.
Issue tracking built for speed. Keyboard-first, sub-100ms UI. Cycles, roadmaps, GitHub integration. I use it to track all DevDigest engineering work.
AI voice dictation for macOS. Works in any app — code editors, browsers, notes. Understands context and formats output appropriately. Faster than typing for prose.
Anthropic's AI. Opus 4.6 for hard problems, Sonnet 4.6 for speed, Haiku 4.5 for cost. 200K context window. Best coding model I've tested. Max plan ($200/mo).
OpenAI's flagship. GPT-4o for general use, o3 for reasoning, Codex for coding. 300M+ weekly users. Tasks, agents, web browsing, DALL-E, code interpreter.
Unified API for 200+ models. One API key, one billing dashboard. OpenAI, Anthropic, Google, Meta, Mistral, and more. Automatic fallbacks and load balancing.
I make videos showing how to actually use these tools to build real projects.
