Agents Never Sleep vs Capacity: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of Agents Never Sleep and Capacity — 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.
Capacity
Capacity
AI no-code app builder that turns a plain-English idea into a live web app with logins, payments, and a shareable URL.
Key features
- Conversational app spec: Capacity asks clarifying questions about your idea before it starts building instead of guessing your intent.
- Full production stack: generated apps include member accounts, logins, saved data, and payments — real product features, not demo scaffolding.
- One-click deploy: publish your app to a shareable URL the same day, with custom domains available in minutes.
- AI co-founder support: describe any bug or change in natural language and the agent explains, fixes, and iterates on the app for you.
- Codebase export: on Growth and above you can export the full underlying codebase so a developer can take it over anytime.
- Multi-device design: responsive UI for phones, tablets, and desktop comes standard, with style controlled by plain-English direction.
- Credit-based billing: credits are consumed only when the AI is actively building or editing, and never expire.
- macOS desktop app: dedicated Mac client for local building without a credit card required.
Best for
- Non-technical founder validates an MVP idea by describing it and shipping a working prototype the same day.
- Solopreneur builds a paid membership app with logins, saved profiles, and Stripe-style payments without hiring a developer.
- Small business owner spins up an internal tool or client portal with a custom domain in minutes.
- Product manager prototypes a v0 of a new feature and iterates by conversation before handing an exported codebase to engineers.
- Creator ships a niche landing page or micro-app around a specific audience using only plain-English direction.
- Team standardizes multiple internal apps under one workspace and manages usage with credit budgets.
