OpenKBS vs Bolt
AWS Lambda vs Supabase Edge Functions. Different infrastructure, different performance profiles. Here's how OpenKBS and Bolt compare on real production benchmarks.
OpenKBS is 2.8x faster per request — 128ms median CRUD latency vs Bolt's 363ms. OpenKBS also wins on throughput — 370 RPS at 500 concurrent users compared to Bolt's 203 RPS. Both handle all concurrency levels with zero errors, but OpenKBS maintains significantly lower latency at every stage.

OpenKBS vs Bolt in depth
OpenKBS and Bolt both clear 500 concurrent users without errors, which makes this a comparison about how much speed and headroom you get rather than whether the platform survives load. On single requests OpenKBS is far quicker. Its CRUD operations average about 128ms at the median against Bolt's 363ms, and its ping leads 117ms to 180ms. OpenKBS runs generated code on AWS Lambda and CloudFront, while Bolt uses Supabase Edge Functions.
The query gap is just as wide. OpenKBS reads a filtered list in 126ms to Bolt's 296ms and runs an aggregation in 127ms against 317ms. Bolt's update operation is its slowest at 451ms, more than three times OpenKBS's 138ms. Both keep reasonable tails, but OpenKBS does so at less than half the latency, so every interaction in a typical app returns sooner.
This is the closest part of the matchup, because Bolt scales well. At 500 concurrent users Bolt holds 203 requests per second with zero errors, a genuinely strong result. OpenKBS goes further on the same test, sustaining 370 requests per second at a 1.3s median against Bolt's 2.3s. At 100 concurrent users OpenKBS serves 248 requests per second to Bolt's 156. Bolt is reliable under load, OpenKBS is reliable and faster.
OpenKBS leads the benchmark with a production score of 78 and a B grade, while Bolt scores 68 with a C. Bolt is a solid choice for full-stack apps that need to absorb traffic spikes and value its browser-based workflow. OpenKBS is the pick when you want that same spike resilience plus markedly lower latency and room to scale into the tens of thousands of concurrent users.
Frequently asked questions
Is OpenKBS faster than Bolt?
Yes. OpenKBS delivers 128ms median CRUD latency compared to Bolt's 363ms — about 2.8x faster on individual API requests. The gap comes from the infrastructure — AWS Lambda with CloudFront vs Supabase Edge Functions.
Which handles traffic spikes better?
OpenKBS. At 500 concurrent users, OpenKBS serves 370 RPS with 1.3s median latency. Bolt reaches 203 RPS with 2.3s median latency at the same level. Both handle all concurrency levels without errors, but OpenKBS maintains nearly 2x the throughput.
Which has better query performance?
OpenKBS — its filtered list queries run at 126ms vs Bolt's 296ms, and aggregation queries at 127ms vs 317ms. OpenKBS uses Neon Postgres while Bolt uses Supabase Postgres, but the runtime difference accounts for most of the gap.
Should I choose OpenKBS or Bolt?
Choose OpenKBS for production-grade performance, AWS-native infrastructure, and the highest throughput in our benchmarks. Choose Bolt for a browser-based dev environment with WebContainers, team collaboration features, and quick full-stack app scaffolding.
