TL;DR: Five serious tools landed at $20/month in June 2026, Windsurf became Devin Desktop overnight, and GitHub Copilot switched to AI credits billing mid-sprint for thousands of teams. Cursor still wins for IDE-native daily coding; Claude Code wins for terminal-based agentic work; Kiro is the only spec-first option. If you’re already paying $20/month somewhere, the real question is whether your workflow is editor-centric or terminal-centric — that splits the field cleanly.

Honest take: For a solo developer writing code in an IDE 8 hours a day, Cursor Pro at $20 is still the default pick in June 2026 — Tab autocomplete with Cursor Fusion and Composer 2.5 context awareness remain unmatched in any editor. If you want agents that work while you sleep, Claude Code Max 5x is the serious answer.

What changed in the last two weeks

Three things happened between May 27 and June 6 that make any comparison written before June 2026 stale:

GitHub Copilot switched to AI credits billing on June 1, 2026. Code review workflows in Copilot now consume GitHub Actions minutes in addition to AI credits. The flat-rate feeling of “$10/month for Copilot Pro” is gone — you burn credits against a cap, then either stop or pay overages. Full details in the GitHub Copilot June 2026 billing change breakdown.

Windsurf became Devin Desktop on June 2, 2026. Cognition — the maker of the autonomous Devin agent — shipped an over-the-air update that rebranded Windsurf to Devin Desktop. Plans, pricing, settings, extensions, keybindings, and MCP connections carried over automatically. The IDE’s default screen is now the Agent Command Center, a Kanban board of all your running agents. See the full rebrand breakdown.

Cursor updated Teams pricing. Standard seats run $32/seat/month (annual) and Premium seats $96/seat/month (annual), up from the older flat rate. Teams can mix seat types. Full pricing breakdown here.

If any of these three tools are in your current stack, re-evaluating right now is worth the 15 minutes.

The $20/month tier: what you actually get

The convergence to $20/month is real and intentional — every vendor benchmarks against Cursor Pro. Here’s what each tool delivers at that price point today, verified June 6, 2026:

Tool$20/month planTab / inline completionsAgentic featuresModel at entry tier

Antigravity ProPro ($20/mo)Via agent contextMulti-agent, background tasks, browserGemini 2.5 Pro

Copilot is the only outlier at $10/month for Pro — but the $15/month AI credit budget burns faster than most developers expect once Agent Mode is active. The effective “fully capable” tier for Copilot is Pro+ at $39/month with $70 credits.

Architecture: what kind of agent is each one?

Not all “AI coding agents” are the same class of tool. The architecture determines which category of problem each one is designed to solve.

Editor-native agents

Cursor and Devin Desktop are both VS Code forks with agent capabilities built into the editor itself. Cursor’s Composer and Devin Desktop’s Agent Command Center accept natural-language tasks and execute them against your open codebase. The editor is the primary interface.

GitHub Copilot is an extension — it runs inside VS Code, JetBrains, and GitHub.com, but it’s not the host editor. This matters: Copilot can’t spawn persistent background agents that run after you close the editor. Agent Mode tasks are scoped to active sessions.

AWS Kiro is a VS Code–based IDE but with a fundamentally different workflow model. Rather than accepting ad-hoc natural-language prompts, Kiro expects you to write structured specs (requirements + acceptance criteria) before the agent generates any code. The “Auto” agent then routes your spec to a mix of frontier models — primarily Claude Sonnet 4.5 plus task-specialized models — for execution.

Google Antigravity 2.0 is a standalone desktop app with a CLI and an SDK, launched at Google I/O 2026. It’s the least tightly coupled to any specific editor, which gives it flexibility (run it alongside Cursor, JetBrains, or Zed) but means inline autocomplete quality lags behind Cursor’s native Fusion model.

Terminal/CLI agents

Claude Code and OpenAI Codex CLI both live in your terminal.

Claude Code runs locally. You point it at a directory and it reads files, writes changes, runs shell commands, calls external APIs, and spawns subagents — all within a single session that you can observe in real time:

$ claude --version
claude-code 1.4.2

$ claude -p "Refactor all API handlers in src/api/ to use async/await. Run the test suite after each file change and revert if tests fail."
✔ Reading src/api/ (14 files)
✔ Refactoring src/api/users.ts — tests pass
✔ Refactoring src/api/orders.ts — tests pass
✗ src/api/payments.ts — 2 test failures, reverting...

Codex CLI submits tasks to OpenAI’s sandboxed cloud environment, not your local machine:

$ codex run "Fix all TypeScript strict-mode errors in src/ and output a summary"
# Task submitted. ID: task_8f2x4k91
# Estimated completion: 3–8 minutes
# Run: codex status task_8f2x4k91

The architectural split is clear: Claude Code is for developers who want agents working on their local filesystem with full observability; Codex CLI is for developers who want async cloud tasks they can fire and forget.

Per-use-case verdicts

Daily IDE coding — who wins

Cursor Pro ($20/month).

Tab autocomplete powered by Cursor Fusion remains the fastest, highest-context completion in any VS Code-based editor as of June 2026. Composer 2.5 handles multi-file changes cleanly. The $20 credit cap per seat is a real constraint, but most solo developers working interactively don’t hit it in a normal coding day.

Devin Desktop is the closest competitor at the same $20 price. SWE-1.6 is a strong model and Cascade handles long editing sessions well. The Agent Command Center default view post-rebrand adds friction for developers who want to write code, not manage a Kanban board. Wait 60 days for Cognition to smooth out the ACP rollout before switching your primary editor.

Unattended agents — who wins

Claude Code Max 5x ($100/month).

The Pro tier’s ~45 prompts per 5-hour window was designed for interactive sessions. Unattended overnight agents — processing hundreds of files, running test suites, committing incremental changes — will hit this limit, fail mid-task, and leave the repository in a partial state unless you explicitly handle retries. Max 5x opens up 5× the capacity and is the real minimum for serious agentic workloads.

Claude Code’s CLAUDE.md context file, subagent spawning, and shell integration have no equivalent in the other six tools. See the Claude Code power user setup guide for the CLAUDE.md patterns that prevent mid-run failures.

PR automation inside GitHub — who wins

GitHub Copilot Pro+ ($39/month).

Copilot is the only tool in this comparison that’s native to GitHub.com itself. Code review runs in the PR diff. The agent can open pull requests from natural language. Actions integration (now more tightly coupled after the June 1 billing switch) means the entire CI/CD loop lives in one system.

The practical rule after the June 1 billing change: Copilot agent tasks that trigger GitHub Actions workflows burn both AI credits and Actions minutes. The $39/month plan includes $70 of AI credits — budget those carefully if your PRs trigger long test suites.

Spec-driven development with AWS integration — who wins

AWS Kiro Pro ($20/month), or Pro+ ($40/month) for teams.

Kiro’s differentiating feature is the Spec system: you define requirements in a structured format before the agent writes any code. This forces planning before action, which reduces the hallucination-driven code sprawl you get when you hand a raw LLM a vague task. Agent hooks — automated triggers on file save, create, or delete — let you build CI-like workflows without shell scripts.

The practical problem on Pro: 1,000 credits/month sounds like a lot until you run a complex multi-file spec. A spec that touches 10+ interconnected files with dependency resolution can cost 200–300 credits per run. Overage at $0.04/credit adds up quickly. Use Kiro Pro for solo exploration; use Pro+ ($40/month) for teams doing this daily.

Multi-agent orchestration — who wins

Devin Desktop Teams + $40/month Devin usage.

Post-rebrand, Devin Desktop’s Agent Command Center is the most mature multi-agent interface of the seven. Every agent — local and cloud — appears in a Kanban view sorted by status: in progress, blocked, ready for review. Blocked agents surface for human approval without interrupting other running agents.

This requires the Teams plan: add Devin Desktop at $40/month for usage across Devin Cloud, Desktop, CLI, and Review, on top of a base Teams seat. For teams running parallel agents on feature branches simultaneously, it’s the most operationally complete option available right now. The parallel agents orchestration guide covers setting this up across Devin Desktop and Cursor simultaneously.

Browser automation + custom SDK workflows — who wins

Google Antigravity 2.0 Pro ($20/month).

Antigravity’s browser subagent is genuinely unique among the seven — it can navigate pages, fill forms, and extract data as part of a coding workflow. No other tool in this comparison includes this natively. The SDK lets you build custom subagent pipelines, making Antigravity the right pick if you’re building a product on top of an AI agent, not just using one.

One hard deadline for existing Gemini CLI users: Google is deprecating Gemini CLI on June 18, 2026. If your CI pipelines, Makefile scripts, or shell automations call gemini directly, they will break after that date. Check Google’s official migration guide before then.

The $100/month tier: what you unlock

When $20/month runs out, all seven tools have a step-up tier. Here’s what each looks like at the $100/month mark:

Tool$100/mo equivalentUsage increaseKey unlock
Cursor Pro+$60/mo (no $100 tier)3× vs ProMore API credits
Cursor Ultra$200/mo (nearest tier above $60)20× vs ProPriority feature access

Devin Desktop Max$200/mo (no $100 tier)Higher usage cap—
Antigravity AI Ultra$100/mo5× limits vs ProHigher concurrency, priority

Claude Code Max 5x and GitHub Copilot Max are direct competitors at $100/month. Claude Code’s advantage is depth of local agentic capability. Copilot Max’s advantage is GitHub-native integration and the full suite of enterprise controls. For teams that live in GitHub, Copilot Max is the cleaner fit. For developers running autonomous agents on local codebases, Claude Code Max 5x is the pick.

The one problem each tool hasn’t solved

Vendor marketing doesn’t mention these. Real developers hit them.

Cursor: The credit cliff. Hobby is free but limited; Pro is $20 but caps out for heavy Composer users; the next meaningful step is Pro+ at $60/month, then Ultra at $200/month. There’s nothing between $60 and $200 for individual plans — a gap that forces heavy users to overpay or run dry mid-sprint.

Claude Code: The Pro tier rate limit is aggressive for agentic use. Approximately 45 prompts per 5-hour window was calibrated for interactive use; unattended agent sessions that call models hundreds of times will fail and leave repositories in partial states. The solution is Max 5x at $100/month — but that’s a 5× price jump from Pro.

GitHub Copilot: The June 1, 2026 billing change was not communicated clearly. Developers who set up Copilot agent workflows once and then ignored billing are now getting surprise charges when Actions minutes are consumed by Copilot code review triggers. Audit your usage logs now if you run any Copilot Agent or code review automations.

Codex CLI: Cloud-only execution. Tasks run in OpenAI’s sandboxed environment, not your local machine. For codebases with proprietary data, air-gapped environments, or compliance requirements that prohibit sending source code to third-party APIs, this is a hard blocker with no workaround.

Kiro: Credit unpredictability on the Pro plan. A single large spec execution — 10+ files, complex dependency graphs — can consume 200–300 credits. On a 1,000-credit plan, that’s 25–33% of your monthly budget in one task. Teams not tracking credit consumption find themselves locked out before month end.

Devin Desktop: The ACP Kanban view is the new default screen and there is no setting to change this back to the classic Cascade editor view on launch. Developers who want to go straight to code must press Cmd/Ctrl+Shift+E every time they open the app. It’s a minor friction point but a real daily annoyance until Cognition adds a preference toggle.

Antigravity 2.0: The Gemini CLI deprecation deadline on June 18, 2026 is affecting real production pipelines. The migration process is not zero-effort for teams with automated scripts, and Google’s in-app notification for this deadline is easy to miss. Check every shell script, CI config, and Makefile that calls gemini before June 18.

FAQ

Can I run multiple of these tools at the same time?
Yes, and many developers do. The most common combination: Cursor Pro for interactive coding, Claude Code for overnight agents or large-scope refactors, and Copilot for PR review inside GitHub. Each tool covers a different part of the workflow. The combined cost of Cursor Pro + Copilot Pro is $30/month and covers 90% of what most individual developers need.

Does Devin Desktop still work like Windsurf?
For code editing, yes. Cascade AI, extension compatibility, keybindings, MCP connections, and existing plans all carried over in the June 2 update. The new default home screen is the Agent Command Center — press Cmd/Ctrl+Shift+E to go directly to the editor. All Windsurf extensions continue working without reinstallation.

Is Claude Code free to try?
There is no free tier. New Anthropic accounts receive a small API credit balance that lets you run a few sessions before paying. Pro at $20/month is the minimum for a real evaluation.

Which tool works best with local LLMs?
None of the seven in this comparison are optimized for local models out of the box. For local LLM + coding tool stacks, the purpose-built setup guides are: Continue.dev + Ollama, Cline + LM Studio, and Aider + LM Studio. For the hardware requirements behind running coding models locally, runaihome.com covers GPU and VRAM requirements.

Is GitHub Copilot Free still available to new users?
New sign-ups to Copilot Free are temporarily paused. Existing Free users can maintain access; Pro, Pro+, and Max upgrades are available to existing subscribers. New users are being directed to a waitlist.

What’s the cheapest way to get a capable coding agent today?
GitHub Copilot Pro at $10/month remains the lowest entry price for a full-featured agent. OpenAI Codex CLI is included with ChatGPT Plus ($20/month), so if you already subscribe to Plus, Codex CLI costs you nothing additional.
