Agents Never Sleep vs Yansu: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of Agents Never Sleep and Yansu — 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.
Yansu
Isoform
A proactive desktop agent that observes your work and turns it into reusable knowledge, handoffs, and automations without prompting.
Key features
- Proactive Observation: Continuously observes user activity (desktop, messaging, file interactions) and converts recurring patterns into structured knowledge without explicit prompting.
- Crystallized Context: Transforms raw activity into concise, reusable knowledge entries that can be surfaced to agents as a single relevant sentence instead of full transcripts.
- Bundled CLI Interface: Ships with a bundled yansu CLI that is the primary interface for integrations and handoffs, providing commands like status, login, and activity summary for continuity across sessions.
- Agent Skill Handoff: Provides a yansu.skill integration that hands a targeted slice of personal context to other AI agents on demand, enabling those agents to start 'warm' and avoid repeated re-introductions.
- Local Runtime & Bundles: Desktop app includes runtime bundles (bun, ffmpeg, sherpa-onnx, etc.) and runs locally; the CLI and binaries must be present for the skill and integrations to work.
- Background Operation & Auto-Update: Runs in the background and checks for updates shortly after launch and periodically (~every 30 minutes), applying new versions in-place and restarting the app automatically.
- Cross-Platform Desktop Client: Native installers and archives for macOS (.dmg), Windows (.zip) and Linux (.tar.gz) with checksums for download verification and platform-specific installation guidance.
- Native desktop clients for macOS, Windows, and Linux (distributions: .dmg for macOS, .zip for Windows, .tar.gz for Linux)
- Bundled absolute-path CLI as primary interface (examples: /Applications/Yansu.app/Contents/Resources/yansu-cli-bundle/bin/yansu status)
- Yansu.skill (SKILL.md) to integrate and hand off concise, relevant context slices to other AI agents
- Yansu Agent releases for syncing project knowledge with the Yansu cloud (optional component)
- Local observation that crystallizes user activity into structured knowledge usable for handoffs and automations
- Strict dependency on the bundled CLI — skill will error if the desktop app/CLI is not installed or running
- Auto-update mechanism: checks ~3 seconds after launch and every ~30 minutes; applies updates in-place and restarts the app
- Release artifacts include checksums.txt with SHA-256 hashes for verification
- Windows-specific bundling requires extraction (sherpa-onnx DLL and helper binaries must sit next to Yansu.exe); Linux binary expects sibling runtime bundles (bun-bundle, ffmpeg-bundle, etc.)
- Common CLI commands referenced: status, login, activity summary (used to verify running/signed-in state and request activity data)
Best for
- Continuity Across Sessions: Maintain context across days for long-running tasks so you don't need to re-explain project decisions when returning to work.
- Agent-Assisted Handoffs: Hand off an in-progress job to another team member or automated agent by providing the crystallized knowledge entry and required state through the CLI/skill.
- Contextual Agent Queries: When using conversational or task agents, surface only the single most relevant sentence of personal context so the agent can answer with knowledge about your preferences and prior decisions.
- Automating Repetitive Workflows: Detect repeatable sequences of actions and convert them into automations or documented handoffs to reduce manual repetition.
- Project Knowledge Syncing: Use the Yansu Agent releases/component to sync a project's local knowledge base with a central store for team onboarding and reduced ramp time.
- Local-First Privacy Workflows: Capture and use personal context locally via the bundled runtime and CLI to enable personalized assistance while minimizing unnecessary external exposure.
- Maintain continuity across days by capturing decisions and context so other agents start with relevant history
- Handoff entire jobs to teammates or agents without reintroducing context
- Surface concise, privacy-minded context snippets to chat agents when they need personal context
- Sync project knowledge bases locally and with cloud (via Yansu Agent) for developer workflows
- Enable automations and repeatable workflows based on observed user patterns
