Guides: The Best Agentic IDEs in 2026

Two years ago the AI code editor was an autocomplete with ambitions. In 2026 it is an agentic IDE: you hand it a goal, and an autonomous agent plans the work, edits across your whole repository, runs the tests, reads the errors, and tries again — while you watch from the driver’s seat. The category is real, the tools are impressive, and nearly all of them are forks of the open-source VS Code editor with an agent and a supervision surface grafted on top.

They are built for one shape of work exceptionally well: a developer sitting at a machine, in the inner loop, steering an agent through a hard change. That is a genuinely valuable thing to be good at. But it is also a ceiling. The instant you want work to happen when nobody is at the keyboard — overnight, on a schedule, triggered by an alert, kicked off from a Slack thread — the editor-shaped tool runs out of road. Here is the 2026 field, and where the road ends for each of them.

Cursor: the incumbent, still a desktop editor

Cursor, from Anysphere, is the tool that made the category mainstream. It is a fast, local, VS Code–based editor with Tab autocomplete, a multi-file Composer, and an Agent mode that runs terminal commands and edits across a project (Cursor pricing). It has grown outward — an Agents window for running work in parallel, and optional Cloud Agents you can reach from the web, iOS, Slack, GitHub, and Linear (Cursor Cloud). Pricing is per seat: a free Hobby tier, an Individual plan around $20 per month, and Teams from about $32 per user (Cursor pricing).

Cursor is excellent at what it is. But the product you actually drive is the desktop editor; the cloud pieces are an add-on around a local core, and the unit of work is a seat with a person behind it. It is the best expression of the inner loop — not a place agents live on their own.

Google Antigravity: a mission-control view on your desktop

Google Antigravity launched in November 2025 alongside Gemini 3 as Google’s “agentic development platform” (Google’s announcement). Its best idea is the Manager view: a mission-control dashboard, sitting alongside the familiar Editor view, where you spawn and observe several agents working asynchronously across workspaces, each producing verifiable “Artifacts” like task lists and browser recordings. It is a cross-platform desktop app for macOS, Windows, and Linux, and it launched free in public preview with rate-limited Gemini quotas, with heavier use tied to Google’s paid AI subscription tiers (Antigravity overview).

The Manager metaphor is the right instinct — supervise many agents, not one. But it is still a metaphor rendered on your desktop, watched by a person. There is no documented way to schedule a run for 3 a.m., fire one off a webhook, or drive it from your team’s Slack. Close the laptop and the mission control goes dark.

Kiro: spec-driven, and the closest to unattended

Kiro is AWS’s spec-driven agentic IDE and the official successor to Amazon Q Developer, generally available since May 2026 (Kiro). Its signature move is discipline: before it writes code, it turns your prompt into a structured spec — requirements, design, and tasks — then implements against it, generating docs and tests along the way (Kiro specs). Custom agents are versioned personas that live in the repo, and steering files give a project durable context. Crucially, Kiro ships a headless CLI mode that runs non-interactively in CI, plus agent hooks that fire on editor events (Kiro headless mode). Pricing is a free tier plus paid plans from $20 to $200 per user per month (Kiro pricing).

Of the agentic IDEs, Kiro comes closest to running without you — but notice the shape of it: headless in your CI, hooks scoped to the IDE. It automates the pipeline you already own. There is no first-class cron or webhook layer that launches a full session on its own, and no Slack seat where a team drives the work from chat. It is a superb assistant that still assumes an editor and a pipeline you operate.

Trae SOLO and Devin Desktop: the cloud add-on pattern

Trae, ByteDance’s free VS Code–style IDE, adds an autonomous SOLO mode that breaks a natural-language objective into steps and runs multi-step work as concurrent cloud tasks (Trae SOLO). It is free to download, with paid tiers layered on top. Two caveats worth naming: reviewers report that Trae shares telemetry with ByteDance and its affiliates, a real consideration for proprietary code, and its full “requirements → code → test → deploy” pipeline is reported rather than officially documented (Trae).

Devin Desktop is the editor formerly known as Windsurf, rebranded by Cognition in an over-the-air update on June 2, 2026 (Windsurf is now Devin Desktop). It is a local desktop “cockpit” — a Kanban command center over multiple agents, “Spaces” that share context, and Agent Client Protocol support so Codex, Claude Agent, and others run inside it — wired to Cognition’s long-running cloud Devin, which does offer Slack entry and scheduled sessions. Both tools show the same pattern: a strong local editor, with the cloud bolted alongside as an add-on. The desktop is still the front door.

Publicly reported capabilities and pricing as of July 2026. Some figures are vendor-reported; see sources below.

The axis nobody in the IDE market is selling on

Line the tools up and the real distinction is not model quality or how many agents fit in a sidebar. It is presence: does the work require a human at a desk? Every agentic IDE answers yes. The agent is brilliant, but it is a passenger in an editor a person has to open, watch, and keep open. Kiro stretches furthest with headless CI runs, and Devin and Trae lean on a bolted-on cloud, but the product each one is remains a local editor. Their whole design assumes you are there.

That assumption is fine for the inner loop — and terrible for everything else a modern team wants from agents. The nightly dependency bump. The scheduled security sweep. The “a customer filed a bug, open a draft fix before standup” reflex. The teammate in Slack who says “can someone get an agent on this” and wants it to just happen. None of that fits inside a window someone has to be staring at. It needs a runtime, not an editor.

How to choose an agentic development tool

Six questions decide it:

• Does the work need a human at the keyboard? If every task is a developer steering an agent live, an IDE is perfect. If some of it should happen overnight or on a trigger, an editor cannot help you.
• Can it run on a schedule or a webhook? First-class cron and webhook triggers turn maintenance, reviews, and alert-driven fixes into work that launches itself. On the IDEs you get, at most, CI plumbing you build and own.
• How does the team start work? A per-seat editor ties every task to one machine. Chat-native control from Slack and Discord lets anyone kick off and steer an agent from where the team already talks.
• Does a fresh environment know your org? An editor carries your settings; a runtime should carry your conventions. Durable context that preloads onto every new machine is what makes a brand-new session behave like a veteran.
• Are you locked to one agent? Some IDEs are welded to one vendor’s model. A runtime that runs any agent lets you change models without changing tools.
• Can you forecast the bill? Per-seat meters and usage credits punish scale. A flat per-runtime line is what lets a team grow its fleet without a finance review.

The agentic IDEs win the first question when a human is in the loop by design. One platform wins the other five for everyone.

Why Nori Sessions wins

Nori Sessions is not another editor with an agent in the corner. It is the runtime the editors are missing: an ephemeral cloud machine where an agent does the work on its own, with a full terminal and editor waiting for the moment a human wants to jump in. The difference is presence — the work does not need you standing over it.

• Triggers are first-class. Cron and webhook triggers launch sessions with nobody attached — nightly maintenance, scheduled reviews, alert-driven fixes. This very article was researched and opened as a pull request by a scheduled Nori Session.
• Chat-native on Slack and Discord. Start, steer, and check on agents from where your team already works, then drop into the real terminal and editor the second a human wants to take the wheel.
• Every session knows your org. Durable skillsets preload your conventions, tools, and integrations onto every fresh machine, so a brand-new session behaves like it has worked here for months — the org-wide context an editor’s per-project rules can’t match.
• Bring any agent. Run Codex, Claude Code, Gemini, Cursor Agent, or your own harness inside the same session. Keep the agent your team already likes; get unattended runs and chat-native control around it for free.
• A real workspace on demand. Terminal and editor are one click away when you want them — you lose nothing of the hands-on experience, you just stop being required for the work to happen.

And instead of a per-seat meter that climbs with every developer and every credit bucket, Nori Sessions is a flat $50 per runtime per month, with a Premium tier that adds hands-on org setup and dedicated support. It is the predictable price of a fleet of agents that work while your team sleeps.

The bottom line

If your work is a developer in the inner loop, steering an agent through a hard change, the agentic IDEs are outstanding — Cursor for polish, Google Antigravity for its mission-control view, Kiro for spec-driven rigor, Trae and Devin Desktop for their cloud-flavored takes. Buy one; you will be happy. But if what you actually want is agents that run in isolated cloud machines — unattended on triggers, driven from Slack and Discord, running any agent you choose, loaded with your org’s context, at a price a team can budget — you do not want an editor you have to sit in front of. You want the runtime. That is Nori Sessions, and it is already shipping.

Spin up your first Nori Session and let the work happen without you.

Frequently asked questions

What is an agentic IDE?

An agentic IDE is a code editor built around an autonomous AI agent rather than around autocomplete. Instead of suggesting the next line, the agent takes a goal, plans the steps, edits across many files, runs terminal commands, and checks its own work while you supervise. In 2026 the leading examples are Cursor, Google Antigravity, Kiro, Trae SOLO, and Devin Desktop. Most are forks of the open-source VS Code editor with an agent and a supervision surface bolted on top.

Are agentic IDEs like Cursor and Google Antigravity cloud-based?

Mostly no. Cursor, Google Antigravity, Kiro, and Devin Desktop are desktop applications you install and run on your own machine, where the agent works beside you in the editor. Some pair the local editor with optional cloud execution — Cursor has Cloud Agents, Trae SOLO runs concurrent cloud tasks, and Devin Desktop orchestrates cloud Devin — but the product you drive is the local IDE. That is the opposite of a managed cloud session, where the machine and the agent both live in the cloud and you never install anything.

Can an agentic IDE run tasks unattended, without me at the keyboard?

Only partway. An IDE agent runs while the editor is open and you are watching it. Kiro adds a headless CLI mode that runs non-interactively in CI, and its agent hooks fire on editor events like saving a file — real automation, but scoped to the pipeline or the IDE. None of the desktop agentic IDEs ship native cron or webhook triggers that launch work on a schedule or in response to an outside event. Nori Sessions makes cron and webhook triggers first-class, so overnight maintenance and alert-driven fixes launch themselves with nobody attached.

What is the difference between an agentic IDE and a cloud agent session?

An agentic IDE is where a human writes code with an agent’s help — the inner loop, at a desk, one seat at a time. A cloud agent session is a managed, ephemeral machine where an agent does the work on its own, reachable from chat, launched by a schedule or a webhook, and preloaded with your organization’s context. Nori Sessions is the second kind: it still gives you a full terminal and editor when a human wants to take the wheel, but its center of gravity is unattended, chat-native work rather than a local editor.

Can I use my existing coding agent with Nori Sessions?

Yes. Nori Sessions is a runtime rather than an agent, so you run Codex, Claude Code, Gemini, Cursor Agent, or your own harness inside the same managed session. That means you are not forced to abandon the agent your team already likes to get unattended runs and chat-native control. You keep your setup and swap the model underneath it whenever you want.

How much do agentic IDEs cost in 2026?

Most follow a per-seat subscription with usage credits. Cursor runs about $20 per month for an individual and $32 and up per user on Teams; Kiro spans a free tier and paid plans from $20 to $200 per user per month; Trae is free to download with paid tiers on top; Google Antigravity launched as a free, rate-limited preview with heavier use tied to Google’s paid AI tiers. Nori Sessions prices differently: a flat $50 per runtime per month, so a team can grow its fleet of agents without a per-seat meter or a finance review.
