## Hermes-Agent

Hermes-Agent is the officially published agent from Nous Research, distributed free and open source under the MIT license. Rather than a single chat window, it is designed as a long-lived assistant that persists conversations, memories, and self-authored skills between sessions, so solved problems become reusable capabilities instead of one-off prompts. The desktop app and install script support macOS 12+, Windows 10/11, and most Linux distributions.

Its reach is deliberately broad. One agent and one shared memory can connect to Telegram, Discord, Slack, WhatsApp, Signal, email, and the command line, so the same assistant follows you across surfaces. Beyond conversation it can browse and automate the web, use vision, generate images and speech, and reason across multiple models, while isolated subagents handle delegated work with their own terminals and Python RPC scripts to keep the main context light.

Automation and safety are first-class: natural-language scheduling runs recurring reports, backups, and briefings unattended through the gateway, and sandboxing is available across five backends including local, Docker, SSH, Singularity, and Modal with container hardening and namespace isolation. The core agent is free; model providers and optional hosted services are billed separately, and Nous Portal offers usage-based cloud agents in addition to free and low-cost tiers.

**Pricing & Plans:** The Hermes-Agent software is free and open source under the MIT license; model providers and optional hosted services are billed separately. Nous Portal offers a free pay-as-you-go tier plus Plus, Super, and Ultra cloud plans with usage, hosted tools, and cloud hosting, so you can bring your own keys or pay for managed credits.

- **Persistent memory and self-written skills:** Hermes keeps conversations, memories, and skills between sessions, and turns solutions it has already found into reusable capabilities you can call again.
- **Every surface in one agent:** Connect Telegram, Discord, Slack, WhatsApp, Signal, email, and the CLI to a single agent with one shared memory, so context follows you across platforms.
- **Natural-language scheduling:** Describe recurring reports, backups, or daily briefings in plain language and let them run unattended through the gateway.
- **Subagent delegation:** Spawn isolated subagents with their own conversations, terminals, and Python RPC scripts to run zero-context-cost pipelines in parallel.
- **Flexible sandbox backends:** Run untrusted work in local, Docker, SSH, Singularity, or Modal environments with container hardening and namespace isolation.

**Strengths:** Genuinely free and MIT-licensed, with no mandatory subscription to use the core agent; Persistent memory and auto-generated skills make it compound in usefulness over time; Unusually wide platform reach for a single agent, from Telegram to the command line; Multiple sandbox backends and subagent isolation suit serious automation work

**Limitations:** Self-hosting and provider setup demand real technical comfort compared with hosted chat apps; You bring your own model provider keys or pay for Nous Portal credits, so costs vary; Cloud hosting capacity per tier is modest, which can limit heavy always-on workloads

## 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
