Hermes vs. OpenCode
OpenCode is an open-source TUI coding assistant with 75+ providers, SQLite history, embedded WebUI, and 30+ community plugins. Here's how it compares.
OpenCode is a capable coding TUI with excellent provider coverage. Hermes is a persistent server agent. OpenCode has no first-party scheduling, messaging, or automatic cross-session memory.
The details
OpenCode is impressive on provider breadth and extensibility. The gaps are in first-party persistence, scheduling, and messaging.
What OpenCode is
OpenCode is a terminal UI (TUI) coding assistant with an embedded WebUI and optional desktop application. It stores conversation history in SQLite, supports AGENTS.md and CLAUDE.md for project context, and as of January 2026 integrates directly with GitHub Copilot as an official provider. Pricing tiers include OpenCode Go at $10/month and a Zen tier for heavier usage. The 75+ provider count makes it arguably the most provider-agnostic tool in the TUI coding space.
Community plugins vs. automatic skills
OpenCode has 30+ community plugins that can extend its behaviour — including plugins for Telegram, Slack, Discord, and Teams messaging, and at least one community scheduling plugin. These require manual discovery, installation, and configuration. Hermes takes the opposite approach: the agent automatically writes new skill modules based on what it encounters, without any manual plugin management. One is an ecosystem you curate; the other is a system that improves itself.
Scheduling and messaging: the first-party gap
Neither scheduling nor messaging is first-party in OpenCode — they exist only through community plugins, which means variable quality, maintenance uncertainty, and manual setup. Hermes ships scheduling and messaging as core features: 15+ messaging platforms (Slack, Telegram, Discord, WhatsApp, and more) and cron-based scheduling are built in and maintained by the same team that builds the agent. For production deployments where reliability matters, that distinction is significant.
Provider coverage: a genuine OpenCode win
75+ providers is genuinely the widest in the space. If your team uses an uncommon provider — regional cloud APIs, niche inference endpoints, internal model servers — OpenCode is more likely to have native support. Hermes supports multiple providers but does not match this breadth. If provider coverage is the primary constraint, OpenCode has an advantage here.
Mobile access
OpenCode has no mobile surface. The TUI and embedded WebUI are desktop-only. Hermes is reachable from any messaging app that has a mobile client — Telegram, WhatsApp, Slack, and others — so you can query your agent, trigger jobs, and receive results from a phone without any special setup. For on-call engineers or anyone who needs agent access away from a desk, this is a meaningful difference.
