Agents Never Sleep vs Prelint: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of Agents Never Sleep and Prelint — 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.
Prelint
Prelint
AI reviewer that checks every pull request against your ADRs, docs and past decisions to catch product drift before it ships.
Key features
- Context-Aware Review: Reviews each PR against your ADRs, product docs and past decisions instead of only linting style or syntax.
- Product Drift Detection: Flags conflicts, gaps and drift between the PR's intent and your product context inline in the diff.
- Agent Self-Correction: The Prelint agent can self-correct against detected violations before a human reviewer opens the PR.
- GitHub & GitLab Integration: Runs on both major hosted git platforms with native PR/MR integration.
- Isolated Infrastructure: Every organization runs on isolated per-organization infrastructure and Prelint does not train on customer code.
- Usage-Based Pricing: $1 per completed review with $10 in free credits, no seats or subscription.
Best for
- AI-Written PR Triage: A team using coding agents like Copilot or Claude Code lets Prelint gate agent PRs against product intent before humans look.
- Architecture Enforcement: A platform team encodes architecture decisions in ADRs and uses Prelint to catch PRs that violate them.
- Onboarding Safety Net: A new engineer's early PRs get reviewed against product context they haven't fully internalized yet.
- Open Source Maintenance: A maintainer of a public repo enables Prelint (free for OSS) to review incoming contributions for product fit.
- Cost-Controlled Review: A startup wants automated review without paying per developer seat and pays $1 per PR instead.
