As answered by people managing Wallper and Sourcey.
Wallper's answer
Wallper combines beautiful live wallpapers with native macOS performance. No clunky wrappers, no subscriptions. It just works smoothly and with complete control for every screen.
Sourcey's answer:
Sourcey ties startup offers and Agent Readiness findings to source evidence and versioned releases. A report card describes one agent task, its observed result, blockers, and unknowns. Offer records keep the vendor’s terms and eligibility caveats visible. The public record is free to read through the website, JSON, API, and MCP.
Wallper's answer
Most alternatives are either outdated, heavy on resources, or require a login. Wallper is fast, lightweight, fully local, and respects your privacy. Plus, it’s designed specifically for macOS.
Sourcey's answer:
Choose Sourcey when you need the original source behind an offer or a task-level account of what an agent could actually do. It shows uncertainty and release history alongside the finding. Sourcey does not apply for offers or redeem credits on a founder’s behalf.
Wallper's answer
Mac users who care about aesthetics, productivity, and simplicity. Creatives, developers, designers - anyone who wants their desktop to feel alive and personal.
Sourcey's answer:
Founders comparing startup offers, developers evaluating whether an agent can complete a specific task with a service, and agents that consume the public record through HTTP or MCP.
Wallper's answer
Wallper started as a weekend project. After switching from Windows, we couldn’t believe how limited macOS was when it came to live wallpapers — there just wasn’t a clean, native solution like Wallpaper Engine. We built the first version just for ourselves, to bring our desktops to life again. But as we shared it with friends and online communities, it quickly turned into something much bigger. What began as a personal fix is now a fully featured app used by thousands of Mac users around the world.
Wallper's answer
Wallper is built entirely in Swift & SwiftUI. Everything is optimized for macOS with no Electron or cross-platform layers.

Doing all this by hand for every candidate got old fast, so now I lean on Sourcey, a registry that tracks exactly this. It publishes report cards that grade whether an agent can actually sign up, pay, and operate a service on its own,... - Source: dev.to / 16 days ago
