Core Vector // Uncapped Utility Audits

Free Services, Real Limits

"Free" is often a marketing euphemism for a deferred paywall or telemetry collection engine. We audit genuine free services to identify the exact threshold where usage hits throttles, sleep cycles, or paid team gates.

The "Freemium Trap" Checklist

Before adopting any free digital service into a business workflow, audit it against these four red flags.

1. The Proprietary Export Barrier

If a service allows you to input rich structured data but only exports flat compressed PDFs or fragmented single-page summaries, your records are effectively held hostage. Insist on JSON, CSV, or raw SQLite dumps.

2. Sudden Feature Re-categorization

Watch for venture-backed utilities that offer advanced collaboration features free in version 1.0. As growth targets shift, API keys, audit logs, and custom subdomains are systematically moved to $40/user enterprise plans.
