Agentic harness comparison

Amp vs Cursor

Compared on where each one runs, which editors it supports, how autonomous it is, and how it bills — the four things that actually decide Amp vs Cursor. Rankings reflect fit and trade-offs, not a single universal winner; partner links, when present, do not replace that methodology.

Amp

Amp Frontier Corporation's coding agent runs locally in its CLI, in cloud Orbs, or on connected runners, with web and beta macOS/iOS apps sharing threads.

Best for

  • Terminal and cloud agent workflows
  • Teams reviewing model routing and permissions
  • Cross-device threads with explicit visibility controls

Watch out

Hobby is free client access/BYOK or linked subscriptions with paid Orbs; Individual Megawatt is $20/month with 45,000 weighted Orb minutes; Teams adds no extra charge and Enterprise is custom. Gigawatt price and exact included agent allowance are not established by these public pages. Education is $10/month for eligible students/teachers; the captured page does not confirm an extra $10 credit grant. Non-enterprise paid-credit inference has no provider API markup; non-model tools can also charge credits, purchased credits expire after 12 months, and included usage does not roll over. Orbs bill by minute: a1 sizes $0.08–$2.13/hour, largest restricted, and pause after both 5 minutes without agent work and 20 minutes without interaction; idle services do not themselves keep an Orb awake. Mode routing can be pinned: ChatGPT linking alone does not convert every role, and ultra keeps Amp routing. Tools require no approval by default; custom policy plugins are the current control, not an assumed legacy permission mode. Workspace-project threads default shared; personal/no-project threads private, subject to admin controls. Amp-managed inference MDR has safety/legal/model exceptions, sometimes up to 30 days, and does not cover thread storage. Training is off absent explicit opt-in; Enterprise cannot enable it. BYOK/consumer-subscription terms are separate, and Fable BYOK requires retained-data workspace access. CLI docs say Windows via WSL while a native PowerShell installer exists; confirm installed-client support.

HybridHybrid

Cursor

Cursor, now part of SpaceX, offers an AI-native VS Code-based editor, a standalone terminal agent and cloud agents. The IDE path changes editor; the CLI can run beside an existing editor. Grok and Composer are first-party models, with third-party models available subject to plan and policy.

Best for

  • Daily feature work
  • Multi-file edits in-editor
  • Teams already on VS Code

Watch out

SpaceX-owned Cursor currently prices Hobby free, Pro $20/month, Pro+ $60, Ultra $200, Teams Standard $40/user/month and Premium $120 (5x Standard Agent limits). India-only Start is ₹649/month including tax, restricted to Cursor Models and without the Other Models pool or on-demand usage. Individual plans have separate monthly Cursor Models and Other Models pools; third-party models are charged at API rates. Teams/Enterprise add $0.25/MTok on third-party direct, Auto and BYOK usage, not first-party models. Eligible US-only residency adds a 10% model-price uplift. Old $20/$70/$400 included-dollar figures are not currently established (https://cursor.com/pricing; https://cursor.com/docs/models-and-pricing). OpenAI's August 28 notice proposes a November 12, 2026 (2026-11-12) wind-down; it does not prove OpenAI models have already been removed (https://openai.com/index/our-decision-on-cursor-following-its-acquisition-by-spacex/). Privacy Mode prevents training, subject to abuse-investigation retention and explicitly approved non-ZDR models such as Fable; BYOK requests still use Cursor's backend. Current Instant Grep builds/searches its index locally without storing code embeddings, but opened file context can still reach model providers. Ignore rules do not block terminal or MCP reads (https://cursor.com/data-use; https://cursor.com/docs/context/codebase-indexing; https://cursor.com/docs/reference/ignore-file). The retained 65.7% benchmark is an April 19 publisher compilation for Background Agent with Sonnet 4.6, not a current-product measurement or an independently reproduced official submission. CLI/cloud availability means switching IDE is optional (https://cursor.com/docs/cli/overview; https://cursor.com/blog/joining-spacex).

Common questions

Amp vs Cursor

Answered from the verified figures on this page rather than general guidance.

Do I have to change editor to use Amp or Cursor?
Neither does. Amp runs in the terminal + web + beta macos/ios apps alongside any editor and Cursor runs in the ide, standalone cli and cloud agents alongside any editor, so people keep the setup they already have.
How are Amp and Cursor priced?
Both are hybrid. The headline seat or plan price is not the heavy-agent bill — included credits, shared pools, and overages dominate once you loop agents hard. Estimate cost per successful task and set spend caps.
Is Amp or Cursor better for large refactors?
Our catalog classifies Amp as more autonomous (agentic versus hybrid). This describes workflow, not measured refactoring quality. Verify permissions, correctness, editor fit and cost on the same tasks before selecting either.
Should I run Amp and Cursor together?
A combined setup can help when the tools have distinct jobs. Assign clear ownership of files and tasks, review each tool’s permissions and native rule format, and pilot on separate disposable clones before paying for both. Different surfaces alone do not prove a benefit.
Will my project rules transfer between Amp and Cursor?
Usually not automatically. Cursor rules, CLAUDE.md, AGENTS.md, and extension-specific configs are different conventions. Keep one source of truth in the repository (commonly AGENTS.md) and copy or link into each tool’s native format so switching does not wipe months of project teaching.
Is Cursor free enough for daily agent work?
Hobby is a real free forever plan, but Agent and Tab usage are limited — it is not a daily heavy-agent driver. Pro and higher include usage pools; on-demand spend applies after the included allowance. Treat the seat price as a floor, not an unlimited agent budget.
Do coding agents replace code review?
No. Agents can draft patches faster, but they do not remove the need for human review of plans, tool calls, permissions, diffs, tests, and rollback paths. Treat autonomy as a reason for stronger review, not less — see the coding assistant rollout guide at /ai-harnesses/guides/coding-assistant-rollout-guide.
Should we harden MCP before rolling out a coding agent?
Yes for any agent that can install MCP servers or run tools. Maintain a short allowlist, review each server’s folder and network access before install, fail closed on unknown tools, and log tool calls. .cursorignore and similar rules do not block MCP or shell access once a command is approved.
Is Amp free once the CLI is installed?
No. The installer is free, but agent usage can draw from a subscription, workspace credits, linked ChatGPT usage, or remote Orbs. Thread visibility (Private vs Workspace vs Unlisted) is separate from billing — confirm the active workspace and executor before a long run.

Next step

Which one fits

Autonomy and editor constraints decide this far more reliably than a benchmark score.

If most of your week is small, frequent edits, an assistive workflow beats delegation and an agentic harness sits idle while billing. If you regularly hand over work spanning many files, the reverse is true.

Where one tool requires changing editor and the other does not, that difference usually outweighs any capability gap across a team — rollouts fail on adoption, not capability.
