fastbrowse Rule: Adopt Only When a Client Workflow Needs Cited, Credential-Safe Browser Runs

fastbrowse returns answers backed by verbatim quoted page text and keeps credentials out of model prompts via named scoped secrets, which is the specific combination agencies need when a client will check the output or hand over logins. The tier ladder is concrete: Free gives 1 run at a time with 7 day history, Starter at $29/month gives 5 runs with 30 day history plus secrets, profiles, schedules and webhooks, and Pro at $199/month gives 25 runs, 90 day history, session recordings and an audit log. The verdict is blunt that white-label options and multi-tenant client reporting are not documented, so the tool fits agency-operated delivery, not a resold platform.

• •The client workflow repeats at least weekly and produces an answer a client will audit, so verbatim quoted page text matters more than raw speed
• •The workflow touches client logins or payment steps, making named scoped secrets and the pause-for-authorization gate on irreversible actions a delivery requirement
• •The agency can absorb $29/month Starter for 5 concurrent runs and 30 day history, or $199/month Pro when session recordings and the audit log are needed for client reporting
• •Delivery runs through Claude Code, Cursor, or an MCP client, so the team can wire fastbrowse in without building a bespoke browser agent
• •The engagement is scoped as a productized retainer (the $2,250 Starter Workflow at roughly 20h setup) rather than open-ended custom development
