Our take
Pick Dagger if platform teams who will run the OSS engine at $0 while they write a first function, then start Starter’s Try for free and land on $20/month (1 user, 1-month traces) — or Scale at $200/month when they need unlimited users and 1-year traces. Pick Spacelift if platform teams who will stay on Free at $0 (2 users, 1 public worker, no card) while they open a first Stacks list, then request a Starter+ quote
