Del vs Hermes Agentself-hosted vs hands-off.
Hermes Agent is an open-source, self-hosted AI agent from Nous Research that you run yourself, bringing your own model. Del is a proactive personal assistant that lives in your messages, tracking your email, calendar, and tasks and acting on its own. Choose Hermes Agent to own your stack; choose Del for a zero-setup assistant.
What's the main difference between Del and Hermes Agent?
The difference is a stack you run versus an assistant you text. Hermes Agent is an open-source, self-hosted agent from Nous Research: you install it from the terminal, bring your own model, and host it yourself on a VPS, Docker, or serverless infrastructure. You own and can inspect everything, swap among many models or run fully local, and reach it through a desktop app or a messaging gateway. For a developer who wants control, that ownership is the whole point.
Del isn't something you host — it's an assistant you talk to. Del lives in the messaging app you already use, learns how your days run, and takes initiative on its own: rebooking the 10:40 to SFO, chasing Alex's contract, moving your run before the rain. There's no model to pick and no server to run. You text Del like a friend, and Del works for you.
Can Del do everything Hermes Agent does?
No — and for some jobs Hermes Agent is the better tool. If you're a developer who wants to own and audit your agent end to end — running it fully local or on your own VPS so conversations and data never leave your network, swapping among many models with no vendor lock-in, and fanning out scheduled automations across Slack, Discord, and Telegram — that's exactly where Hermes Agent shines, and a managed cloud assistant isn't built for it. Privacy-sensitive and regulated environments where data residency is non-negotiable are its home turf.
Del is built for a different job: running one person's life over text. Del triages your email down to what matters, manages your calendar and tasks, remembers the people and commitments that matter, and follows up until things are actually done. Where Hermes Agent is infrastructure you control, Del is the assistant you offload to.
How does Del handle proactivity differently from Hermes Agent?
Del acts without being prompted or configured — that's the core distinction. Hermes Agent is reactive in conversation and becomes "proactive" only through a built-in cron scheduler that runs the tasks you specify in advance; each scheduled job runs in a blank session with no memory of your history, so it must be fully re-specified. Del starts working on its own, anticipating what you need before you think to ask.
In practice, Del just texts you: "Friday is your anniversary 🥂 Sofia's free that night. The patio list opens at 10; I'll ping you the second it does." No cron job to define, no session to re-specify. As Ben, a Data Scientist at Glean, put it: "Now that I've gotten in the habit of sending everything I need to do to Del, I don't think I could stop using it. It's so good at following up with me and so much better than texting myself reminders."
Pricing reflects the gap in shape, too. Del is a flat $20/month with two weeks free, fully managed. Hermes Agent's software is free and open source, but the real cost is your own model usage plus hosting, and an optional subscription bundles models for a monthly fee — designed for developers who want to own the stack.
Should I use Del or Hermes Agent?
Choose Hermes Agent if you're technically comfortable and want a self-hosted, model-agnostic agent you can run on your own infrastructure — keeping data on your network, avoiding vendor lock-in, and customizing it with plugin tools and self-improving skills. For privacy-sensitive or cost-conscious developers, that ownership is exactly the draw.
Choose Del if you want a proactive personal assistant that handles your email, calendar, tasks, and follow-ups over text, with nothing to install or configure. Del learns who you are and the people in your life, and gets more useful the longer you use Del. The two barely overlap: Hermes Agent is infrastructure for developers; Del is your assistant for everyday life.
Frequently asked
Is Del better than Hermes Agent?
Neither is strictly better — they solve different problems. Hermes Agent is a self-hosted, open-source framework that developers run and configure on their own infrastructure, with full control over models and data. Del proactively manages your personal email, calendar, and tasks over text with nothing to set up. If you want a hands-off personal assistant rather than a stack to host, Del is the better fit.
Does Del replace Hermes Agent?
Only if your need is personal rather than infrastructural. Hermes Agent is built for developers who want to own, host, and customize an agent — choosing their own model and keeping data on their network. Del is built for one person's daily life over text, fully managed. Many people would run Hermes Agent for owned automation and use Del to keep their own day moving.
Do I need to set up servers or config files to use Del?
No. Del needs no hosting, config files, or model keys. There's nothing to install or wire up. You start by texting Del in plain language, and Del learns how your days run and takes initiative on its own. Setup takes about five minutes.
Do I need to download an app to use Del?
No. Del works in the messaging apps you already use — iMessage, WhatsApp, Telegram, and SMS. There's nothing new to open. You start by texting Del.
