Cursor vs Sentry
Both are developer tools. Here is what separates them.
What Cursor is
Cursor is a code editor with a model wired into the editing loop rather than bolted on beside it. Its named surfaces are Tab, Agent, Composer, Bugbot, the Cursor CLI, cloud agents and Automations. Tab is the part you touch most. It predicts multi-line edits, missing import statements, the next place in a file you are likely to edit, and edits that span more than one file. A suggestion is accepted with the Tab key and dismissed with Escape or by carrying on typing, and it can be taken word by word with a modifier and the right arrow key when only part of it is right. Tab can be snoozed for a chosen duration, disabled globally, or disabled for specific file extensions. Agent work also happens outside the editor. Cloud agents run in parallel across multiple repositories. Bugbot reviews pull requests inside GitHub. Agents can be summoned in a Slack channel with a mention and reply with pull request links. Automations run agents on a schedule or from a trigger, for jobs such as fixing a CI failure. The Hobby plan is free and takes no credit card. Pro is $20 per month, Pro Plus $60 and Ultra $200, with Pro Plus carrying three times the agent limits of Pro and Ultra twenty times. Teams Standard seats are $40 per user per month and Teams Premium $120, with Premium at five times the agent limits of Standard. Enterprise is quoted by sales, pools usage across the organisation and can be billed by invoice or purchase order. India has a Start plan at 649 INR per month covering Cursor's own models. Paid plans keep two separate usage pools, one for Cursor's own models and one for third-party models charged at that model's API price, and both reset monthly. Pro, Pro Plus and Ultra include unlimited tab completions. Enterprise administration is granular. Admins can allowlist or blocklist specific repositories, models and MCP servers, and set cost controls per team and per user. SAML single sign-on works with Okta, Azure AD and Google Workspace, SCIM handles user provisioning and seat management, and an API reports how much code was written by AI. Turning on Privacy Mode across an organisation stops customer code being used for model training. Cursor runs on AWS and does not offer an on-premises deployment. It holds SOC 2 Type II certification, runs annual penetration testing, encrypts data at rest with AES-256 and in transit with TLS 1.2 or higher, and states that it holds zero data retention agreements with all of its LLM providers.
What Sentry is
Sentry captures application errors and performance data from code running in production. An error report includes a stack trace that shows the values of local variables at each frame, so the state that produced the failure is visible without reproducing it locally, and breadcrumbs record the sequence of events that led up to it. Distributed tracing links a single request across every service and function call it touches, with the SDK sampling rate set through tracesSampleRate. From that data Sentry detects performance problems on its own, including N plus 1 queries, slow database calls and uncompressed assets. Logs can be filtered on structured attributes such as a customer id rather than by matching raw strings. Session Replay covers web frameworks and mobile through React Native, Android, iOS and Flutter, and flags rage clicks and dead clicks where a user taps an element that does not respond. It masks all text, inputs and media by default before a recording leaves the user's browser. Release Health reports crash free session rates, adoption per version and failure rate. SDKs cover JavaScript, Python, Java, Kotlin, PHP, Ruby, Go, Rust, Elixir, Perl, Scala, .NET and native C and C++, along with mobile and game platforms including Android, Apple, React Native, Flutter, Unity, Unreal Engine and Godot. Sentry integrates with GitHub, Jira and Slack, and can assign a new issue automatically to the developer whose commit introduced it. The free Developer plan is limited to a single user seat and includes 5,000 errors, 5 million spans, 50 session replays, 5GB of logs, 5GB of application metrics, one uptime monitor, one cron monitor, 1GB of attachments and 10 custom dashboards, with a 30 day lookback on data. The Team plan costs $26 per month on annual billing, places no limit on seats, raises the error allowance to 50,000 and extends retention to a 90 day lookback. The Business plan costs $80 per month on annual billing and adds unlimited custom dashboards and 1,000 metric monitors, against 20 on Team. Enterprise is quoted individually with custom quotas on every dimension. Usage above an allowance is charged separately: logs and application metrics beyond the included 5GB cost $0.50 per additional GB, extra uptime monitors $1.00 each and extra cron monitors $0.78 each.
