Why this deal is worth using

The Free Tier savings apply to the Mercury plan tier most teams actually pick — not a stripped-down trial.

Annual plan vs monthly: Free tier vs paid on Mercury: The free tier of Mercury is genuinely useful for evaluation, but the paid plans add the workflow features most teams need by month two — usage limits lift, integrations unlock, and SSO becomes available on the higher tiers.
