Warm pool, node cache, cold

A three-tier start path. The global warm pool, tier one, is why the common case is fast. It powers both code and browser sandboxes.

Warm pool

global, pre-booted VMs

~0.1 s

A pre-booted microVM handed over from the fleet-wide pool in ~130 ms.

Node cache

template cached on the node

~0.4 s

Your template is already cached on the node, so the boot skips the S3 fetch.

Cold

pulled from S3 storage

~ a few seconds

First use of an uncommon template. The rare p99 tail comes from here.

Most sandboxes start from the warm pool. E2B, Modal and Daytona run no live fleet-wide pool, so their fastest path is closer to our node-cache tier.

Start time, measured

Create to first command, from the EU

p50 create to first command, N=20.

Start time, create to first command, EU p50 in milliseconds, measured from Copenhagen, Denmark, 2026-06-17, 20 runs per provider.
Provider	p50 (ms)	p90 (ms)	p99 (ms)	min (ms)
Lelantosus	394	1400	1430	303
E2B	589	685	809	543
Modal	1412	1851	2187	1166
Daytona	2263	2664	2686	1875

Honest note: the median is served from the warm pool; the p99 tail is the rare drop to the cold tier. E2B is a little more consistent at that tail; Lelantos wins the median and the floor, which is what most workloads feel.

Bring a paused sandbox back

Resume time, EU p50, measured from Copenhagen, Denmark, 2026-06-17.
Provider	Resume p50	Mechanism
Lelantosus	368 ms	pause / resume (in-RAM freeze)
E2B	841 ms	pause / resume (memory + fs)
Daytona	2047 ms	stop / start (filesystem only)
Modal	not available	no memory-snapshot in its SDK

A 2 vCPU, 4 GiB sandbox over 24 hours

Per-second billing, no minimums.

Cost at 2 vCPU, 4 GiB over 24 hours, computed from each provider’s published rates, verified 2026-06-17.
Provider	$/hour	$/day	Notes
Lelantosus	$0.116	$2.78	no base fee
Daytona	$0.166	$3.97	+43%
Modal	$0.239	$5.73	+106%
E2B Pro	$0.166	$8.97	incl. $150 / month base fee

Honest framing: Lelantos is the cheapest turnkey, E2B-compatible sandbox. It is not cheaper than raw-infra primitives like a bare VPS, which carry no sandbox SDK.

The full matrix

Lelantos vs E2B, Modal and Daytona across start time, resume, cost, EU residency, API compatibility, isolation, open source and compliance, verified 2026-06-17.
Dimension	Lelantos	E2B	Modal	Daytona
Start time (EU p50)	394 ms	589 ms	1412 ms	2263 ms
Resume (EU p50)	368 ms	841 ms	n/a	2047 ms
Live global warm pool	yes, ~130 ms	no	no	no
Cost / day	$2.78	$8.97	$5.73	$3.97
EU data residency	native, default	Pro-gated	plan-gated	yes
E2B-compatible API	yes, drop-in	the standard	no	no
Isolation	Firecracker microVM	Firecracker microVM	gVisor	Sysbox container
Open source	SDKs	SDK + infra	SDKs	full core (AGPL)
Compliance	GDPR; SOC2 on roadmap	enterprise tier	SOC2 + HIPAA	SOC2 (I)

Where a competitor leads, we say so. Daytona ships more open source. Modal carries more compliance today. E2B is a little more consistent at the p99 tail. We lead on what matters for EU agent workloads: speed, price, residency.

Browser sandboxes

A browser inside a sandbox, not just a hosted browser

Browserbase and Browserless are browser-hosting services: an isolated, managed browser to connect to, and that is the product. Lelantos gives you a full microVM sandbox that happens to include a browser, so the same place that drives the page can also run your code. Browse and compute in one place, no second system, no data egress, no glue code.

Browser session speed, warm, create to a usable connection from the EU, measured 2026-06-17.
Provider	Warm session	Model
Browserbase	~0.9 s	browser hosting (BaaS), CDP
Lelantos · native /rpcus	~1.5 s	full sandbox, NDJSON protocol
Lelantos · CDPus	~1.9 s	full sandbox, Playwright-compatible
Browserless	~2.0 s	browser hosting (BaaS), shared workers

Each Lelantos browser runs in its own Firecracker microVM. Browserbase uses a dedicated VM per session; Browserless co-locates sessions on shared workers. Honest note: Browserbase creates a session a little faster (~0.9 s vs our ~1.5 s native /rpc); our advantage is the fusion of browse and compute, isolation, and EU residency. Connect over standard CDP for Playwright and Puppeteer, or our lighter native NDJSON /rpc.

Lelantos vs Browserbase

A browser inside an agentic sandbox, EU-native, browse and compute in one place.

Lelantos vs Browserless

Per-session microVM isolation, faster warm via /rpc, and EU residency by default.

One-on-one comparisons

Lelantos vs E2B

The cheaper, EU-native sandbox. No $150/month base fee, drop-in compatible.

Lelantos vs Modal

EU-native and Firecracker-isolated, where Modal routes large I/O through us-east.

Lelantos vs Daytona

About 5x faster sandbox starts from the EU, on a microVM not a container.

How we measured

Methodology

Where: from a developer machine in Copenhagen, Denmark, on a normal EU connection. These numbers reflect what an EU customer sees.
Code sandbox: wall-clock from create to first successful command, 20 runs per provider, median reported. Resume measures time to bring a paused sandbox back to a command.
Cost: computed from each provider’s published rates for an equal 2 vCPU, 4 GiB configuration.
Reproducible: an open benchmark you can run yourself. Start time is geography-dependent; near a provider’s home region its numbers improve. These are EU figures.
Date: 2026-06-17. Competitor pricing and features verified the same week.
