YapYap

A fast, private, extensible desktop client for WhatsApp Web, for Linux, Windows and macOS.

YapYap is unofficial. It is not affiliated with, endorsed by, or sponsored by WhatsApp or Meta. "WhatsApp" is a trademark of its owner. YapYap loads the official WhatsApp Web in a hardened desktop shell. It does not reimplement WhatsApp's protocol and does not automate your account.

Install

Download YapYap for Linux, Windows or macOS from the releases page, or add the apt, dnf or pacman repository at packages.guita.org, as the install guide explains, then get started in six steps. Each release's changes are in CHANGELOG.md.

Status

YapYap is young: v0.1.0 is its first release. Follow what comes next on the project board and in docs/progress.md.

Highlights

• Multiple accounts with fully isolated sessions
• Native notifications, tray or menu bar with unread counts, and do-not-disturb
• Recovery tools that fix a stuck session without logging you out
• A sandboxed, signed extension system with per-account permissions, and a marketplace of official and reviewed extensions
• An optional "bring your own model" AI assistant that suggests replies beneath the chat, with your own key or a model on your computer; nothing is sent without your click
• Call recording, which starts only when you click Record and confirm that everyone on the call agrees
• No telemetry

Support YapYap

YapYap is free, with no ads and no telemetry. If it is useful to you, you can sponsor its development. Sponsorships pay for what building YapYap costs:

• Development tools: a Claude subscription for AI-assisted development. A higher plan means fewer pauses when the usage limit runs out.
• Code signing: certificates for macOS and Windows, so YapYap installs without security warnings.

Supporters

YapYap's development is supported by Ensita, a nonprofit that builds free, open-source apps that keep your data yours, and mentors new developers.
