TermFlow vs WezTerm
WezTerm is the strongest open-source terminal for automation — cross-platform, with a powerful CLI. TermFlow adds a first-party HTTP API and MCP server, the contract agents speak.
Two philosophies.
WezTerm
The automation-strong OSS terminal.
GPU-accelerated, cross-platform, and scriptable in Lua, with a built-in multiplexer and a genuinely capable CLI (wezterm cli send-text / get-text / split-pane). Of the open terminals, it has the strongest first-party drive surface — and it’s free.
TermFlow
The same reach, an agent-native contract.
TermFlow covers the same three platforms, but exposes control as a documented HTTP API and a first-party MCP server — the contract AI agents already speak — instead of a CLI you script and a community MCP bridge you install.

Where WezTerm wins
WezTerm is the terminal we most respect on this axis: it's cross-platform, GPU-fast, has a built-in multiplexer, and its wezterm cli genuinely lets an external program send input and read output — first-party, today, for free. Its Lua scripting is more powerful than our config. The one thing it doesn't ship is an agent-native contract: control is a CLI you script, and its MCP servers are community projects. TermFlow's bet is that agents want a documented HTTP API and a first-party MCP server — the same contract on every OS.
Common questions.
Isn't WezTerm's CLI enough to drive it?
For scripting, yes — it's excellent. The gap is standardization: agents increasingly speak MCP, and WezTerm's MCP support is community-maintained. TermFlow ships MCP and HTTP first-party.
Is WezTerm faster?
On raw GPU rendering it's strong, and its multiplexer is mature. We're not claiming a performance crown — our differentiator is the agent contract, not benchmarks.
Is it free?
Yes, Apache-2.0 — API and MCP included, free on your machine. See pricing.
