Agents Never Sleep vs Osaurus: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of Agents Never Sleep and Osaurus — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
Agents Never Sleep
Agents Never Sleep
A tiny $4.99 Mac menu bar app that keeps long-running AI agents alive with the laptop lid closed, using one three-level slider.
Key features
- Closed-Lid Operation: Keeps agents and background jobs running with the MacBook lid shut, which the built-in caffeinate command cannot do.
- Three-Level Slider: One control with Sleepy, Awake, and Never sleeps settings, so changing sleep behavior takes a single drag rather than a terminal command.
- Menu Bar Only: Lives entirely in the menu bar with no window, dock icon, or configuration screens to manage.
- Native and Tiny: A small native macOS binary rather than a wrapped web app, minimizing overhead on a machine already running agents.
- Zero Data Collection: No telemetry, analytics, or tracking; what runs on the machine stays on the machine.
- Safe Revert: Toggling back down restores normal sleep behavior, avoiding the common mistake of leaving sudo pmset -a disablesleep 1 permanently enabled.
- No-Questions Refund: A 14-day money-back guarantee with no form to fill in and no reason required.
Best for
- Overnight Agent Runs: Letting a coding agent work through a long task while the laptop is closed and put away.
- Long Builds and Tests: Preventing a multi-hour build, test suite, or data job from being interrupted mid-run by sleep.
- Mobile Working: Carrying a MacBook between rooms or offices without propping the lid open to keep a job alive.
- Model Downloads and Training: Keeping large model downloads or local fine-tuning runs going unattended.
- Avoiding pmset Mistakes: Replacing manual sudo pmset toggles that are easy to enable and easy to forget to undo.
- Remote Sessions: Keeping a Mac reachable and working for a remote session or background service while it sits closed on a desk.
Osaurus
Osaurus, Inc.
Native macOS harness for AI agents that runs any local model on Apple Silicon with persistent memory and offline execution.
Key features
- Native Apple Silicon App: Built in Swift and optimized for M-series chips so inference runs locally with millisecond round trips.
- One-Click Model Runtimes: Connect Ollama, MLX, or LM Studio in a single click and switch between them from the UI.
- Fully Offline Mode: Turn Wi-Fi off and Osaurus keeps working — no server calls, no telemetry, no data leaves the Mac.
- Cloud Fallback: Add ChatGPT, Claude, or Gemini for tasks that demand a frontier model without losing the shared memory context.
- Persistent Shared Memory: One memory layer spans local and cloud models so agents remember prior sessions across providers.
- Autonomous Agents: Build agents driven by voice control, folder watchers, browser plugins, or parallel jobs that keep working in the background.
- File and Tool Execution: Drop in a folder and Osaurus can read, write, and run tools against local files like a resident assistant.
- MIT-Licensed and Free: Open source under MIT with no subscription, usage caps, or billing — fork it and ship it.
Best for
- Privacy-First Work: Run an assistant over sensitive code, contracts, or medical notes without any data leaving your Mac.
- Offline Field Use: Keep an AI assistant available on flights, in remote locations, or on air-gapped machines.
- Local Development Copilot: Point Osaurus at a repo and let a local model refactor, review, or generate code without cloud costs.
- Personal Agent Automation: Set up folder-watcher or voice-controlled agents to file downloads, transcribe recordings, or summarize new emails.
- Multi-Model Comparison: Route the same prompt through local and cloud models to compare outputs while reusing one memory context.
- Open-Source Base for Products: Fork the MIT-licensed harness to build a branded desktop AI app on top of Apple Silicon inference.
