## Dedalus Labs

Dedalus Labs is a developer infrastructure company that focuses on one hard problem in agent development: keeping agents alive and stateful. Its core product, Dedalus Machines, is a class of persistent virtual machines built to host agents that never sleep. Rather than paying for an ephemeral container that dies the moment a request ends, developers get a VM that persists, so an agent can hold context, files, background jobs, and long-running processes across sessions.

The platform targets teams building autonomous agents, coding agents, and MCP (Model Context Protocol) integrations. Because idle compute is billed as free and active compute is billed per second, the model fits workloads that are bursty — an agent that mostly waits for a trigger, then does heavy work for a short window. Developers work with standard VM primitives, so existing code, tools, and serverless-style patterns can often be moved over without a rewrite.

The pricing page advertises a $20 sign-up credit to test the platform, a Pro plan at $20 per month, and per-second billing for active compute. It positions itself in the same neighborhood as agent sandbox and cloud VM providers, but emphasizes always-on persistence and fast wakeups rather than pure cold-start sandboxing.

**Pricing & Plans:** Free Trial with $20 sign-up credit; Pro plan at $20/month. Active compute is billed per second, while idle compute is not charged.

- **Persistent stateful VMs:** Each Dedalus Machine keeps its filesystem, processes, and in-memory state alive between agent turns, eliminating expensive cold starts.
- **Near-instant wakeups:** Machines are designed to resume in milliseconds so agents can respond quickly to new requests after being idle.
- **Pay-as-you-go compute:** Per-second billing for active compute with idle time free, which suits bursty agent workloads that wait between tasks.
- **Agent and MCP friendly:** Built for autonomous agents and Model Context Protocol servers that need a stable, long-lived host environment.
- **Standard VM primitives:** You work with familiar file, process, and networking primitives, making it easier to port existing agent code.

**Strengths:** Persistent state removes repeated cold-start overhead for agents; Idle compute is free, so always-on agents are affordable; Per-second billing aligns cost with actual usage; Familiar VM primitives lower the migration effort

**Limitations:** Pricing details beyond the Pro tier are limited on the public site; Less suitable for purely stateless, one-shot workloads; Requires infrastructure knowledge compared to fully managed agent platforms

## Rivet.dev

At its core Rivet replaces the container per agent with an in-process primitive. An Actor runs inside your existing Node.js or Bun backend rather than in its own container or VM, which is why Rivet reports cold starts measured in single-digit milliseconds and a footprint of tens of kilobytes per Actor instead of hundreds of megabytes. Each Actor carries a SQLite database for memory, can access a filesystem and shell, sleeps when idle, and wakes with its durable state ready for the next request.

The platform handles the operational pieces teams usually build themselves: fault tolerance that reschedules Actors when a node goes down, multi-region placement that routes requests to wherever an Actor currently lives, end-to-end type safety where Actor definitions generate client types, and scheduling via cron or self-set timestamps. Storage is pulled apart into two tiers — a fast SSD for instant writes and object storage that settles writes at a fraction of the cost — so running many small databases stays affordable.

Rivet positions itself as infrastructure for the "agentic era" and can be deployed as a managed cloud, inside your own VPC through a bring-your-own-cloud model, or fully self-hosted down to air-gapped networks. It is open source under Apache 2.0, backed by Y Combinator and a16z Speedrun, and integrates with popular coding agents and frameworks.

**Pricing & Plans:** Rivet Cloud uses a plan-plus-nodes model. The control plane is Free ($0) for prototyping, Hobby at $10/month, Team at $120/month, and Enterprise at $900/month, each raising control-plane redundancy, Actor Node caps, and support. Actor Nodes are billed per month on top, from $4.20 (R-5) to $94.50 (R-160). Self-hosting is free and open source under Apache 2.0, and startups from Y Combinator or a16z Speedrun get 50% off the Team plan for 12 months.

- **Durable actors with persistent state:** Every Actor gets a SQLite database and a filesystem, so an agent's memory and progress survive restarts and idle periods without a separate database.
- **Lightweight secure sandboxing:** Run untrusted or AI-generated code on your own infrastructure with fine-grained control over network access, filesystem permissions, and resource limits.
- **Fault tolerance and workflows:** A node failure reschedules its Actors elsewhere with state intact, and multi-step work replays after a crash — with no checkpointing harness to build yourself.
- **Realtime and multiplayer:** Address an Actor directly over HTTP or hold a live WebSocket, and use the React SDK to subscribe components to an Actor's state in real time.
- **One-binary deployment and observability:** Ship with a single stateless Rust binary, embeds storage in S3-compatible buckets, and emits OpenTelemetry traces, metrics, and logs to your existing collector.

**Strengths:** Four-digit millisecond cold starts and a very small per-Actor memory footprint let a single server host far more agents; Open source (Apache 2.0) with a single Rust binary, so it can be self-hosted, run in a VPC, or air-gapped; Durable state via per-Actor SQLite plus object-storage-backed tiers keeps agents restart-safe and cheap; Strong developer ergonomics: typed SDKs, a React SDK, WebSocket networking, and OpenTelemetry baked in

**Limitations:** Requires Node.js or Bun and a working Rust-based control plane deployment for self-hosting, so it favors backend engineers over no-code users; Advanced durability and sandboxing concepts (Actors, WarpDrive storage) carry a learning curve; Managed cloud cost scales with Actor Nodes, which can climb for many mid-sized/sized nodes; Enterprise features like multi-tenancy and hardened compliance guidance sit behind sales conversations
