Questions people ask
What is Rapto?
Rapto is an in-memory NoSQL database written in Zig that includes AOF (append-only file) persistence, hosted as a public open-source project by the raptodb organization on GitHub.
Who is Rapto designed for?
It's intended for engineers and database developers who work on performance-critical applications and need an in-memory data store.
How does Rapto handle multiple queries at once?
Rapto uses a concept called a 'batch,' an ordered sequence of queries sent together in a single request; the queries in a batch are indivisible (executed in order without another batch interrupting them) but not atomic, meaning a failed query does not roll back the others.
Is the Rapto server multi-threaded?
No, the server is single-threaded and uses an event-driven, epoll-based event poller, with performance benefiting as more concurrent clients keep the event loop fed.
How much does Rapto cost?
Rapto is free and open source, distributed under the Apache-2.0 license.

Is rapto production-ready?
Legit.Show scores rapto 85 out of 100 — the simple average of its 3 measured frames. Legit.Show ran its deterministic 7-Frame production-readiness benchmark on rapto (github assessment), measured from the public surface with no LLM in the scoring path. Its strongest frame is Standards; its weakest is Discoverability. 3 of the seven frames returned a score; Performance, Accessibility, Privacy and Reliability were not measurable on this service and are recorded as null — not as zero. Maintenance is an additional frame from the open-source teardown, scored separately from the seven. Every frame it averages is published with its evidence on the Legit.Show listing.
The 7 Frames
- Performance — not measurable on this service (null — not scored as 0)
