Qursor
Best alternatives to Qursor in 2026
When you ask an AI coding assistant to "make this look like that button on this other website," it's usually guessing from a screenshot, which wastes tokens and produces approximate results. Qursor fixes this specific, narrow problem: it's a Chrome extension that lets you click any element on any live webpage and instantly copy its actual DOM structure, CSS, fonts, and spacing as clean, structured text an AI can read precisely, or export the element outright as HTML, CSS, or React-ready JSX. It's a small, focused developer tool rather than a broad platform — no dashboards, no team features, just a point-and-click workflow for pulling precise UI context out of any site (including localhost during development) and into an AI coding assistant's context window. Pricing is unusually simple for this category: a genuinely limited free tier (3 picks per day), then $29/year or a $39 one-time lifetime purchase for unlimited use — cheap enough that the decision to pay barely requires justification.

#1
#3
A grammar checker that runs entirely on your machine — no account, no server, no text ever leaving your computer — built into your code editor by the team behind WordPress.com.
github.com
- ✓ 100% local, aucune donnée transmise
- ✓ Consommation mémoire très faible
#4
Gives an AI coding agent a real memory of your codebase — the decisions made, the approaches that failed, the constraints that matter — so it stops re-learning your project from scratch in every new session.
autoloops.ai
- ✓ Fully open source and free, with no cloud sync or telemetry
- ✓ 100% local storage — codebase context never leaves your machine
#5
A single web page with 40+ everyday developer utilities — JSON formatter, regex tester, base64 encoder, JWT decoder and more — that runs entirely in your browser with zero tracking and zero accounts.
github.com
- ✓ 100% client-side — nothing you paste in ever leaves your browser
- ✓ 40+ utilities consolidated in one place with bookmarkable URLs
#6
An open-source, Alibaba-built code review tool that reads your Git diffs and leaves precise, line-by-line comments — combining hard-coded security checks with an LLM for the judgment calls.
github.com
- ✓ Free, open source (Apache 2.0), and actively maintained
- ✓ Hybrid architecture gives consistent vulnerability coverage plus nuanced LLM feedback
#7
A free command-line tool that shows you exactly what's running on your computer's localhost ports and lets you kill it, replacing the usual mess of lsof, ss, and manually hunting for stuck processes. Not to be confused with the SonarQube code-quality prod
github.com
- ✓ Replaces manual lsof/ss/netstat commands with one readable command
- ✓ Shows Docker container names, Compose projects, and resource usage alongside process info
#8
A free terminal app that lets you run several AI coding agents at once and keep track of what each one is doing, instead of juggling a pile of separate terminal windows or tabs.
github.com
- ✓ Real-time visibility into the status and lifecycle of each running agent
- ✓ Session persistence — agents keep running after terminal detachment
#9
A free, open-source tool that turns an entire codebase — code, docs, database schemas, config files — into a map of how everything connects, so an AI coding assistant can find the right file instead of guessing.
github.com
- ✓ Local AST parsing via tree-sitter — no LLM required, deterministic graph construction
- ✓ Confidence-tagged edges (EXTRACTED vs INFERRED) for transparent provenance
#10
A free plugin from OpenAI that lets you call on Codex to review your code or hand off a background task without ever leaving Claude Code.
github.com
- ✓ Native integration into the Claude Code workflow, no app-switching required
- ✓ Steerable adversarial reviews that challenge design decisions, not just syntax
#11
A tool that keeps your project's history and past decisions written down as plain text files in your own code repository, so an AI coding assistant can read them instead of forgetting everything between sessions.
github.com
- ✓ Mémoire stockée en Markdown brut, reviewable et diffable comme du code
- ✓ Compatible multi-agents (Claude Code, Codex, Gemini)
#12
A tiny Mac app that lets you peek inside a map file by pressing the Space bar in Finder, instead of opening a full mapping program just to check what's in it.
tony.expert
- ✓ Prévisualisation instantanée dans le Finder sans logiciel SIG complet
- ✓ Supporte de nombreux formats géospatiaux
