MacAIterm · Terminal with an AI agent

A real terminal.
An agent that asks first.

MacAIterm keeps your zsh session at the center and adds an AI agent that works in the same session and directory. Risky commands wait for your approval, and every change is shown as a diff you can undo.

  • Approvals and an audit logFour permission modes, secret masking, a network-block mode and a log of every command the agent ran or tried.
  • Local or cloud modelsOllama, any OpenAI-compatible server, the OpenAI API or Codex CLI. Local models keep the conversation on your Mac.
  • Remote work over SSHThe agent runs commands and edits files on the server. Anything that changes it needs an approval that names the server.
  • Monitoring and filesServer CPU, memory, GPU and disk under the tabs, plus file trees for both machines with SHA-256 verified transfers.
  • v1.0.0
  • macOS 13+
  • Apple silicon

MacCAD 2027 · 2D and 3D CAD

CAD used to mean Windows.
Now it works on the Mac.

MacCAD brings AutoCAD-style drafting to macOS: the command line, aliases and shortcuts you already know, DXF and DWG, real 3D solids, and a Studio for scenes and materials.

  • Familiar from the first minuteMore than 260 commands, object snaps, layers, dimensions, hatches, blocks and layouts.
  • DWG and DXFWorks with DWG and DXF and saves its own format, DXF and DWG R2000. The product page says what was verified.
  • Real 3D solidsBoxes to fillets and slices on the OpenCascade kernel. Open and save STEP, export STL and OBJ.
  • Studio and a local AI helperScenes and materials from one window. An optional AI on your own Mac builds parts from a sentence.
  • v1.0.0
  • macOS 11+
  • Apple silicon
  • 15-day trial

Built on open-source parts: Electron (app shell), OpenCascade and replicad (3D kernel), LibreDWG (DWG), pdf.js (PDF) and polygon-clipping (2D regions). The rest of the engine is built in-house.
