Comparison

Containarium vs Daytona

Q: What is the difference between Containarium and Daytona?

Both run AI-generated code in isolated Linux containers and both speak MCP. The main differences are licensing and posture. Daytona is AGPL-3.0 with a metered hosted cloud as its primary product; its sandboxes lean on snapshots and fork/branch for transient agent runs. Containarium is Apache 2.0, designed to self-host on a VM you own, and gives each agent a persistent long-lived box with optional eBPF per-tenant network isolation.

Q: What license is Daytona, and why does it matter?

Daytona's open source is AGPL-3.0, a network-copyleft license. Many enterprises and SaaS builders avoid AGPL because its obligations can extend to software that merely communicates with it over a network. Containarium is Apache 2.0 — permissive, no network-copyleft — which is simpler to adopt inside a commercial product.

Q: Can I self-host Daytona?

Yes. Daytona's open source can run as a local stack via Docker Compose, and it offers a hybrid mode where Daytona orchestrates while execution happens on machines you manage. That said, the metered hosted cloud is the primary commercial product. Containarium is built so a single self-hosted VM is the first-class path.

Q: Does Daytona support MCP?

Yes — Daytona ships a first-class MCP server that lets an external agent create and manage sandboxes, run code, and do file and Git operations. That is orchestration-layer MCP. Containarium runs an MCP server inside each box, so the agent gets shell and file operations on the box directly. Both use MCP, at different layers.

Q: Which is better for permissive licensing and self-hosting?

Containarium. Apache 2.0 plus a first-class single-VM self-host path makes it straightforward to embed in a commercial product and to keep agent code and data inside your own network.

Both run AI-generated code in isolated Linux containers, and both speak MCP. The real differences are licensing and posture: Daytona is AGPL-3.0 with a metered hosted cloud as its primary product; Containarium is Apache 2.0, built to self-host on a VM you own, with a persistent box per agent. Here's an honest side-by-side.

Choose Containarium when…

You want a permissive license — Apache 2.0, no AGPL network-copyleft to clear with legal.
Self-host on one VM is the goal, with flat infra cost instead of per-hour metering.
You want a persistent box an agent lives in, plus eBPF per-tenant network isolation.
You want GPU passthrough on your own hardware at near-zero marginal cost.

Choose Daytona when…

You want a managed cloud with very fast sandbox creation and don't mind metering.
Fork / branch / snapshot-mid-execution for parallel agent runs is core to your loop.
You want SDKs in many languages (Python, TypeScript, Ruby, Go, Java).
AGPL is fine for your use, and a hosted runtime is your preferred path.

Same job — secure execution of AI-generated code. Different defaults: Apache 2.0, self-hosted, persistent vs AGPL, hosted-cloud-first, snapshot/fork.

Side-by-side

Dimension	Containarium	Daytona
License	Apache 2.0 — permissive, no network-copyleft	AGPL-3.0 — network-copyleft
Self-hosting	First-class — one VM you own is the default path	Available (Docker Compose + hybrid BYOC); hosted cloud is primary
Isolation	LXC container + optional eBPF per-tenant network policy (deny-by-default)	Namespace-isolated OCI containers
Per-agent model	Persistent long-lived box; state survives until you delete it	Stateful sandboxes with snapshots, volumes, and fork / branch
Primary interface	In-box MCP server + CLI	SDKs (Python, TS, Ruby, Go, Java) + an MCP orchestration server
Networking	Built-in sentinel: routable hostname, TLS, SSH routing	Exposed sandbox ports / preview links
GPU	Passthrough on your own GPU host — flat cost	Managed GPUs on the cloud, billed per hour
Cost shape	Self-host: flat infra cost · Cloud: hybrid per-box pricing	Per-resource-hour metered (vCPU / RAM / storage / GPU)

License: Apache 2.0 vs AGPL-3.0

This is the cleanest difference. Daytona's open source is AGPL-3.0, a network-copyleft license: its obligations can reach software that merely communicates with it over a network, which is why many enterprises and SaaS builders route AGPL through legal review or avoid it outright. Containarium is Apache 2.0 — permissive, no network-copyleft — so it's straightforward to embed inside a commercial product without that overhead.

Self-host as the default, not a metered cloud

Daytona can be self-hosted — a local Docker Compose stack, plus a hybrid mode where Daytona orchestrates and execution runs on your machines. But the center of gravity is the per-resource-hour hosted cloud. Containarium is built the other way around: a single self-hosted VM is the first-class path, agent code and data stay in your network, and the cost is your flat infra bill rather than a meter that compounds with usage.

Network isolation with eBPF

Both products isolate workloads in Linux containers. Containarium adds an optional eBPF per-tenant network policy enforced in the kernel — deny-by-default egress with a CIDR/domain allowlist — so a misbehaving agent can't quietly reach the rest of your network or the open internet. If blast-radius control on the network is part of your threat model, that's a concrete defense-in-depth layer.

Where Daytona genuinely shines

To be fair: Daytona's fork / branch and snapshot-mid-execution model is a real strength for fan-out agent workloads — clone a running sandbox into many parallel branches, explore each, keep the winner. If that pattern is core to your product, Daytona is built for it. Containarium's strength is the opposite shape: a durable box an agent owns over time, on infrastructure you control.
