Hermes Agent vs OpenCode is one of my favourite comparisons because the answer is “both, together”. OpenCode is a free, open-source coding agent with free models built in; Hermes is a free, always-on agent that runs your workflows. In my setup, OpenCode’s free models are the brain inside Hermes. In the video below I build an AI automation machine with OpenCode. Here’s how they compare.
Key takeaways
- OpenCode: free coding agent with free models like DeepSeek V4.1 Flash.
- Hermes: free always-on agent with memory, cron and messaging.
- Use OpenCode’s free models as Hermes’s brain.
- Both are open source and cost nothing to start.

My free stack: OpenCode inside Hermes
This is how I run a lot of work for free: Hermes is the agent, and OpenCode provides a free brain such as DeepSeek V4.1 Flash. I’ve used this exact stack to analyse Search Console data and plan GEO content — see my GEO for websites guide. OpenCode is also a provider option inside Hermes (OpenCode Zen and OpenCode Go).
When to use OpenCode on its own
- Quick coding jobs and prototypes.
- Building apps from screenshots with vision models.
- Testing new free models as they launch.
- Coding when your paid model is rate limited.
When to use Hermes
- Scheduled jobs and reports.
- Tasks across your apps and messaging platforms.
- Long-running work on a VPS.
- Anything that benefits from memory and reusable skills.
Free models to try
OpenCode regularly offers free models — recently DeepSeek V4.1 Flash, GLM 5.3 Flash, Nemotron 3.5 Super VL and others. Free windows change, so keep a backup model ready in both tools.
How I set up the free stack
Install OpenCode and Hermes. In OpenCode, check which free models are available — recently DeepSeek V4.1 Flash has been a great choice. In Hermes, add OpenCode as a provider (OpenCode Zen or OpenCode Go) in hermes model, select the free model, and save it in its own profile. Now Hermes’ memory, skills and scheduling run on a free brain. When a free window closes, switch the profile to another free model.
Coding vs operating
The simplest way to think about it: OpenCode is where you build, Hermes is where things run. OpenCode is excellent for quick coding sessions, especially with vision models that can read screenshots. Hermes is where scheduled jobs, reports and messaging workflows live. Many of my automations start as an OpenCode session and end up as a Hermes skill.
What to watch out for
Free models can be rate limited or change without notice, so always keep a second free model ready in both tools. Review code before running it, especially if Hermes will run it on a schedule with access to your files or accounts. And keep approvals on in Hermes for anything that sends messages or deletes files.
Best choice by type of user
- Beginners: start with Hermes Desktop and add OpenCode as a free model source.
- Developers: start with OpenCode for coding, add Hermes for automation.
- Agencies: use the pair to run client workflows on free models and keep costs near zero.
- Creators: OpenCode to build small tools, Hermes to publish and report on a schedule.
Whichever you choose, start with one real job, keep approvals on for anything risky, and expand once it’s working reliably. The best agent is the one you actually use every day, and the fastest way to find it is to test it on your own work rather than reading feature lists.
Common mistakes
Expecting OpenCode to run scheduled jobs on its own is one; it’s a coding agent, not an always-on assistant. Another is leaving Hermes on a paid model for every routine job when a free OpenCode model would do. And a third is not keeping a backup free model — when a free window closes, your automations stop until you switch. Avoid those three and the free stack runs smoothly for months.
Get started this week: install OpenCode, pick a free model, add it to Hermes, and schedule one daily job.
The bottom line on Hermes Agent vs OpenCode
In Hermes Agent vs OpenCode, OpenCode is the free coder and free brain; Hermes is the free operator. Put them together and you have a powerful agent stack for nothing.
The free stack is the best way to learn agents without spending anything: OpenCode gives you free models and a fast coding agent, and Hermes turns those free models into an assistant that remembers you, runs jobs on a schedule and messages you the results. When you’re ready for more power, swap in a paid model for the hard jobs and keep the free one for everything else.
