Lelantos vs Daytona: about 5x faster sandbox starts
From the EU, Lelantos starts in 394 ms versus Daytona's 2263 ms, about 5x faster, on a Firecracker microVM rather than a Sysbox container. Cheaper too: $2.78/day vs $3.97.
The spine of the move
About 5x faster to ready
From Copenhagen, Lelantos starts in 394 ms at p50 versus Daytona 2263 ms, and resumes in 368 ms versus 2047 ms.
Firecracker microVM, not a container
Lelantos isolates each sandbox in a Firecracker microVM. Daytona uses a Sysbox container, a shallower boundary.
Cheaper per hour
Lelantos is $2.78 per day at 2 vCPU and 4 GiB versus Daytona $3.97, per-second billing, no minimums.
E2B-compatible out of the box
Lelantos runs the e2b SDK directly. Daytona has no E2B-compatible API, so existing E2B code can move straight over.
Lelantos vs Daytona, the cells that matter
| Dimension | Lelantos | Daytona |
|---|---|---|
| Start time (EU p50) | 394 ms | 2263 ms |
| Resume (EU p50) | 368 ms | 2047 ms |
| Isolation | Firecracker microVM | Sysbox container |
| Cost / day (2 vCPU, 4 GiB) | $2.78 | $3.97 |
| E2B-compatible API | yes, drop-in | no |
| EU data residency | native, default | yes |
| Open source | SDKs | full core (AGPL) |
| Compliance | GDPR; SOC2 on roadmap | SOC2 (I) |
The honest note
Daytona ships more open source: its core is AGPL-3.0 and self-hostable, with a large community. Lelantos open-sources its SDKs but keeps the core closed. If a fully open-source, self-hostable core is what you need, Daytona has it. We lead on start speed, isolation depth, cost and E2B compatibility.
Questions people ask
- Is Lelantos faster than Daytona?
- Yes. From the EU, Lelantos starts in 394 ms at p50 versus Daytona 2263 ms, about 5x faster, measured from Copenhagen on 2026-06-17, create to first command, 20 runs per provider.
- How is Lelantos isolation different from Daytona?
- Lelantos runs each sandbox in a Firecracker microVM, a hardware-virtualized boundary. Daytona uses a Sysbox container. The microVM is a deeper isolation boundary.
- Is Lelantos cheaper than Daytona?
- Yes. At 2 vCPU and 4 GiB over 24 hours, Lelantos costs $2.78 per day versus Daytona at $3.97 per day.
- Does Lelantos have an E2B-compatible API like Daytona?
- Lelantos runs the e2b SDK directly as a drop-in. Daytona has no E2B-compatible API, so moving to Lelantos can mean reusing your existing E2B code.
- Does Lelantos resume sandboxes faster than Daytona?
- Yes. From the EU, Lelantos resumes a paused sandbox in 368 ms versus Daytona 2047 ms, since Daytona does stop/start on the filesystem rather than an in-RAM freeze.
