Frequently asked questions
Is Emergent faster than Bolt?
Yes. Emergent delivers 151ms median CRUD latency compared to Bolt's 363ms — about 2.4x faster on individual API requests. Emergent's managed runtime eliminates cold starts entirely, giving predictable performance on every request.
Which handles traffic spikes better?
Bolt. At 500 concurrent users, Bolt serves 203 RPS with zero errors and 2.3s median latency. Emergent breaks down at the same level — 91% error rate with 6.3s median latency and only 77 RPS. For apps that expect traffic spikes, Bolt is the safer choice.
Which has better query performance?
Emergent — its filtered list queries run at 159ms vs Bolt's 296ms, and aggregation queries at 153ms vs 317ms. Emergent is roughly 2x faster on complex queries, likely due to its managed runtime eliminating edge function overhead.
Should I choose Emergent or Bolt?
Choose Emergent if consistent speed matters and your traffic is moderate — it delivers the most predictable latency in our benchmarks. Choose Bolt if you need a browser-based dev environment, team collaboration, and proven high-concurrency handling.
