We just finished our website migration from Vercel to GCP to save $50 monthly. If you can, migrate it out ASAP to other cloud platform, like AWS and GCP.

Vercel is expensive and has many hidden fees, like $10 per month for monitoring (this should be free), web analytics Plus (google analytics for free) and source images 5$ per 1000 (what is this?).

Have no idea why Vercel is desperate to charge user money.
