Yaak: A Fast, Pluggable, and Secure Bruno Alternative (2025)

Article

Bruno launched in 2022, but got its break in 2023 when Insomnia forced its users to sign up for a cloud account. Bruno’s plain-text file format and ability to integrate with Git made it a safe choice for developers looking for a local-first API client.

Yaak is the best Bruno alternative if you're looking for a polished, secure, and extensible API client.

Bruno continues to be a popular choice for developers, but there are a few key reasons to consider alternatives.

🦬 Introducing Yaak

Bruno and Yaak share a similar mission: bring back fast, local-first API tools that work with Git. Where Yaak differs is in its focus on performance, customization, and overall experience. It’s a joy to use.

🚀 Fast and polished

Yaak is built using Rust and React. It opens instantly, handles large workspaces with ease, and feels more native than other API clients.

  • Launches in milliseconds
  • Lightweight memory footprint
  • Zero lag for common interactions

Yaak just feels better is difficult to convey, so here’s a demo of Yaak’s multi-select sidebar—one of many examples of Yaak getting the fundamentals right.

It’s details like this that make Yaak stand apart from Bruno.

🔒 Security that scales with you

Since working with APIs often requires sending sensitive secrets for things like authentication, security is a top priority for Yaak.

  • App data never leaves your computer (unless you share explicitly)
  • Secrets can be encrypted using your OS keychain
  • Sensitive values are obscured by default
  • No telemetry, error tracking, or other analytics included

In Yaak, secrets can optionally be encrypted using your OS keychain, keeping things safe, but also allowing secure sharing of workspaces using Yaak’s Git integration.

🧩 Extensible via plugins

Yaak is built from the ground up to be extensible. In fact, much of Yaak’s functionality is already powered by its plugin system, including template functions, authentication, themes, and data importers (Postman, etc).

  • Install community plugins from the plugin directory.
  • Write plugins as simple TypeScript modules
  • Extend Yaak to suit your needs

This makes Yaak more adaptable for advanced use cases like internal APIs, advanced workflows, and custom authentication.

💜 Indie and open source

Yaak is fully open source whereas Bruno is “open core” and does not share the source of its premium features. This is crucial for large companies who want to run security audits on the software they use.

As an indie, I’m able to focus on performance, privacy, and long-term sustainability, without pressure from VCs or large payroll requirements.

  • No signup required, no telemetry, and no cloud lock-in
  • Fully open source with a transparent, auditable codebase
  • Funded by the community for aligned incentive
  • Guided by users using public feedback

If you value developer-owned tools and want to support software that respects your workflow, Yaak is for you.
