Direct answer
Browser and computer-use agents are powerful and fragile. Use them for constrained internal tasks with recording, least privilege, and human gates - not as unsupervised employees on production admin panels.
What they are
Agents that click UIs or control a desktop when APIs are missing.
Why teams want them
Legacy portals, partner sites, no API budget.
Risks
Credential theft via page content, prompt injection from untrusted HTML, irreversible clicks, non-reproducible failures, audit gaps.
Safer pattern
Dedicated browser profile, vaulted credentials, allowlisted domains, step caps, human confirmation on submit/pay/delete, full session logs.
Prefer APIs when possible
API agents are easier to test, scope, and rate-limit than pixel-level automation.
How Northstar fits
Prefer API-first pilots with Northstar: solutions.
FAQ
For narrow, monitored paths maybe. For open-ended “do my job” - no.
