AI coding agents and editors worth using in 2026
Coding tools changed more in the last two years than in the ten before. Autocomplete turned into chat, chat turned into agents, and now people run several agents in parallel.
These are the AI coding tools from my library that I'd still recommend, grouped by how you like to work.
Editors and assistants
- Cursor🔒 Pro
The AI-first code editor most people start with: chat, edits across files, and agent mode in a VS Code-style editor.
- Claude →
Anthropic's assistant, strong at reading large codebases, explaining code and writing it.
- Codeium🔒 Pro
Free code completion and chat for most editors.
- Replit🔒 Pro
Build and run full apps in the browser with an AI agent; nothing to install.
- Phind🔒 Pro
An AI search engine tuned for developer questions.
Open-source and terminal agents
- Aider🔒 Pro
AI pair programmer in your terminal that edits your git repo directly.
- Kilo Code🔒 Pro
Open-source coding agent as a VS Code extension.
- Refact.ai🔒 Pro
Open-source autonomous agent for software engineering tasks.
Running agents in parallel
The newest category: tools that manage several coding agents at once, so you review results instead of waiting on one agent.
- Superset🔒 Pro
Run 10+ coding agents in parallel on your own machine.
- opcode🔒 Pro
A desktop companion for Claude Code sessions and agents.
- Plannotator🔒 Pro
Review and annotate an agent's plan and code before it lands.
- Byterover🔒 Pro
A shared memory layer so coding agents remember project context.
Quality, testing and environments
- Qodo🔒 Pro
AI focused on tests and code review, not only generation.
- Zencoder🔒 Pro
Coding agent that plans and implements changes across a repo.
- Ona (formerly Gitpod)🔒 Pro
Cloud dev environments where agents can work safely.
