Open-source macOS launchers compared: Ueli, Kando, and the rest

"Open source macOS launcher" is a small but real category in 2026. Most of the major launchers — Raycast, Alfred, LaunchBar, CmdSpace — are closed-source. If your threat model or your principles require open-source software in your hotkey chain, the candidate set is short and the trade-offs are different from the closed-source category. This post is the honest tour.

I will cover four projects that are actually maintained as of mid-2026, where they fit, and what you give up versus a closed-source equivalent. If you skim, the takeaways: Ueli is the most mature option, Kando is the most interesting newcomer, Quicksilver is mature but graying, and there is a real argument for not insisting on open source at all in this category.

Why the open-source launcher category is small

Building a launcher that competes with Raycast or Alfred is a multi-year, multi-developer effort. Closed-source launchers monetize through licenses or subscriptions; open-source projects rely on volunteer time, sponsorships, or a single maintainer's evening hours. The economics make it hard for any one OSS project to match the polish of a venture-backed competitor.

That does not mean OSS launchers are bad. It means the trade-off is real and you should know it before you switch.

Ueli — the most mature open-source option

Ueli is an Electron-based open-source launcher with builds for macOS and Windows. The repo on GitHub is active, the maintainer responds to issues, and the feature set covers what most users need.

What Ueli does well:

• Cross-platform — same launcher on macOS and Windows is unusual.
• Plugin system for extensibility.
• File search, calculator, currency conversion, color picker, system commands.
• Active maintainer who ships releases regularly.
• Honest about being Electron-based, no pretending otherwise.

Where Ueli struggles:

• Electron runtime — idle memory around 150-200 MB.
• Cold-search latency around 60 ms, noticeably behind native launchers.
• UI animations occasionally chug on older Intel Macs.
• Plugin ecosystem is small compared to Raycast's extension store.

If you want one open-source recommendation in 2026, Ueli is it. The Electron tax is real but bearable on modern Apple Silicon Macs.

Kando — the newcomer worth watching

Kando is a pie-menu launcher rather than a list-based one. You bind a hotkey, hold it, and a radial menu appears around your cursor with action targets. It is a different interaction model from Spotlight/Raycast/CmdSpace, closer to the radial menus power users sometimes wire up with BetterTouchTool or Karabiner.

What Kando does well:

• Cross-platform (Linux, macOS, Windows).
• Active development by a small team.
• The pie-menu model genuinely beats list-based launchers for memorizable actions — you build muscle memory by direction, not by name.
• Fully customizable menu definitions.

Where Kando is limited:

• Not a search-style launcher in the Raycast sense; less useful for "I do not remember which app it is" cases.
• Smaller community, fewer how-to resources.
• The interaction model takes a week to get used to.

Kando is not a Raycast replacement. It is a different kind of tool that complements rather than substitutes. Worth installing alongside whatever your primary launcher is.

Quicksilver — the OG, still maintained, hard to recommend new

Quicksilver is the launcher that invented the noun-verb-object grammar that every modern launcher copies. It is still maintained by a small community, still functional on current macOS, still free. The codebase is old and the UI is dense.

What Quicksilver still has:

• The noun-verb-object grammar is genuinely powerful.
• Free, open source, no strings.
• Plugin system with a long-tail catalog of community plugins.
• Loyal users who provide support on forums.

Where Quicksilver struggles:

• UI is unapologetically from a decade-plus ago.
• New macOS releases occasionally break specific features.
• The community is small enough that asking questions can return silence.
• Cold-launch and search latency are slower than native launchers.

I cannot recommend Quicksilver to a new user in 2026. If you have used it for years, you do not need this post. The fuller history of Quicksilver and LaunchBar — both still alive, both still oddly compelling — is in Quicksilver and LaunchBar are still alive in 2026.

"Open source-ish" — what does not really count

A few projects you will see recommended in lists that I want to flag:

• Albert — Linux-focused launcher with a macOS port that is rarely updated. Last meaningful macOS release was years ago. Skip for macOS.
• Plasma KRunner-style ports — exist in theory, do not actually work well on macOS as of 2026.
• Cerebro — was active a few years ago, repo has not had meaningful commits recently. Skip.
• Various AppleScript-based DIY launchers — fine projects, not really competitive with a real launcher app.

If a recommendation list includes any of these without caveats, the author has not used them recently.

The honest argument against insisting on open source

This will be unpopular but worth saying. The reason "I want open source" matters for launchers usually breaks down into three concerns:

1. Security review. "I want to read the code to make sure it does not phone home."
2. Longevity. "I want the project to survive even if the company dies."
3. Customization. "I want to modify behavior to fit my workflow."

For #1, a closed-source launcher with a well-documented privacy posture and a clean network audit (little snitch or similar can confirm) gets you 90% of what reading source would. CmdSpace publishes a network audit and the binary does not phone home; you can verify this without source.

For #2, a closed-source app that ships a clean signed binary continues to work indefinitely even if the company disappears. You will not get new macOS-version compatibility, but the existing version keeps running. The Powerpack-era Alfred installs from 2018 still work today.

For #3, customization in modern launchers happens through commands/extensions, which are themselves often open source (Raycast extensions, CmdSpace commands). The closed-source core is less of a barrier than it sounds.

None of this is a reason to avoid open source. It is a reason to think about which of the three concerns actually applies to you and whether the open-source requirement is the cheapest way to address it.

Recommendations by use case

You want the most polished launcher and openness does not negotiate: Ueli.

You want a different interaction model entirely: Kando, optionally alongside a regular launcher.

You have used Quicksilver since 2010: keep using it.

You are open to a closed-source alternative with verifiable privacy: CmdSpace or Alfred. The best macOS launcher 2026 roundup has the full landscape.

You want the absolute lightest option: Quicksilver's idle memory is hard to beat, with the caveats above.

The bottom line

The open-source launcher category in 2026 is real but small. Ueli is the practical recommendation. Kando is interesting and worth a side-install. Quicksilver is for existing users only. Beyond these three, the recommendations get speculative fast.

If you decide the open-source axis is not the most important one, best macOS launcher 2026 covers the broader landscape, and free Raycast alternative covers the no-subscription axis specifically.
