What people write to us about.
Questions about estimates
Something unclear about a category, a provider or how the math works? Ask — the FAQ covers the common ones first.
Price corrections
Spotted an outdated or wrong price? Tell us the provider and what changed. A wrong price undermines everything, so corrections jump the queue.
Privacy & data requests
Access, deletion or questions about the almost-nothing we collect — see the Privacy Policy, or just email us.
Security reports
Found a vulnerability? Please report it responsibly — details on our Security page.
Help us help you faster.
Including a couple of details up front saves a round trip:
- Which project type or stack category you were looking at.
- The provider and price you're questioning, if it's a correction.
- A link or screenshot when something looks broken.
