Valpas keeps your Mac awake for exactly as long as you say: one switch in the menu bar, a visible countdown, and rules that start and stop it for you. Pick 15 minutes, an hour, four hours or forever.

Features and specs

What each product offers, as listed by its team.

Nullstack 5 features
Valpas 6 features
  • Full-Stack Capabilities
    Nullstack allows for the development of both client-side and server-side functionalities within a single project, providing a more unified development process.
  • Seamless SSR
    It offers built-in support for server-side rendering, improving performance and SEO without the need for complex configurations.
  • Zero tooling
    Nullstack provides a setup that requires minimal configuration and does not depend heavily on additional tools, simplifying the development workflow.
  • Component-based Architecture
    Promotes the use of components, encouraging modularity and reusability of code, which can improve maintainability and scalability of applications.
  • Hot Module Replacement
    Supports HMR, allowing developers to see immediate changes in their applications without refreshing the entire page, improving development efficiency.

Possible disadvantages

  • Smaller Community
    Compared to more established frameworks, Nullstack has a smaller community, which can result in fewer resources and third-party tools.
  • Learning Curve
    Developers need to learn the Nullstack-specific ways of handling both front-end and back-end development, which might be a hurdle for those accustomed to other frameworks.
  • Limited Ecosystem
    Due to its newer and less widely adopted nature, there might be limited third-party libraries and plugins readily available compared to more mature frameworks.
  • Rapidly Evolving
    Being relatively new and possibly evolving quickly, developers might face breaking changes more frequently compared to more established technologies.
  • Countdown in the menu bar
    15 minutes, 30, one hour, two, four or forever, with the time left always visible. Hold Option to pick an end time instead.
  • Starts by itself
    On the power adapter, with an external display attached, while the microphone is in use, or while an app you choose is running.
  • Watches a command
    Type claude, codex or ollama and the Mac stays awake while any of them runs, then sleeps when the agent exits.
  • Stops by itself
    A battery guard ends the session when the charge runs low.
  • Command line
    valpas 45m, valpas run claude, valpas hold 20m and valpas status in the Homebrew and disk-image builds.
  • Valpas Pro: lid closed
    Shut the lid and the Mac keeps working until the session ends. Sleep returns on its own when the session ends, on battery, on quit or when the Mac runs hot.
