Widest SDK coverage (every language/framework you'll touch across client work), and paid plans give you unlimited projects under one org - you pay for event volume, not per client app. That model fits agencies well: 30 small client sites that each throw a trickle of errors cost roughly what one busy app costs. Team plan is ~$26/mo billed annually with default pre-paid volume, Business ~$80/mo. Two warnings: it's per-seat on top of volume, which is the real agency cost driver when you have 8 devs, and it now meters errors, spans, replays and logs separately, so bills are hard to forecast.
