Boxes.dev features and specs

  • Instant macOS Development Environments
    Boxes.dev allows developers to quickly spin up macOS virtual machines for development purposes, significantly reducing the time needed to set up clean development environments compared to manual configuration.
  • Native Apple Silicon Support
    Boxes.dev is built to run natively on Apple Silicon (M1/M2/M3/M4) Macs, leveraging the Apple Virtualization framework for near-native performance without the overhead of traditional emulation.
  • Easy to Use Interface
    The app provides a streamlined, user-friendly interface for creating and managing macOS virtual machines, making virtualization accessible even to developers who aren't familiar with complex VM tooling.
  • Pre-configured Environments
    Boxes.dev offers the ability to create environments with development tools pre-installed or easily configurable, saving developers significant setup time when they need fresh or isolated macOS instances.
  • Snapshot and Restore Capabilities
    Users can take snapshots of their virtual machines and restore them to previous states, which is invaluable for testing, CI/CD workflows, and safely experimenting with system configurations without risk.

Possible disadvantages of Boxes.dev

  • macOS Only
    Boxes.dev is limited to macOS host machines and macOS guest VMs, making it unsuitable for developers who need to run Linux or Windows virtual machines or who work on non-Apple hardware.
  • Paid Software
    Boxes.dev is a commercial product that requires a purchase, which may be a barrier for individual developers or small teams, especially when free alternatives like UTM or raw QEMU exist.
  • Apple Silicon Requirement
    The app primarily targets Apple Silicon Macs, which means developers still using older Intel-based Macs may have limited functionality or may not be able to use the tool at all.
  • Relatively New Product
    As a relatively newer entrant in the virtualization space, Boxes.dev has a smaller community and fewer resources, tutorials, and third-party integrations compared to established tools like Parallels or VMware Fusion.
  • Limited OS Version Support
    Users are generally limited to running macOS versions that Apple's Virtualization framework supports as guests, which can restrict the ability to test on older macOS versions that may still be relevant for compatibility testing.

  • Cold email in 2026: what indie hackers got wrong (with a Python validator I built to enforce the new rules)
    I rebuilt my outreach this week after my reply rate tanked from 4% to <1%. Pulled fresh data from 5+ deliverability blogs (Autobound, MarketingProfs, HyperGen, Instantly), built a Python validator to enforce the new rules across 70+ template files in my repo, and shipped 10 trimmed emails that comply. - Source: dev.to / 4 months ago
  • Org-Level Email Campaigns are Somehow an Unsolved Problem
    Instantly was my final selection given its API was the most robust and well documented. It gave claude full access to campaigns, leads, and sequences while also being capable of sending webhooks on reply and unsubscribe events. - Source: dev.to / 8 months ago
  • Massive drop in sales, need advice
    Anywho, the old mailgun system was able to send emails immediately + had images in them. The recommendations we got were to remove ALL images, and instantly.ai has to delay a few minutes between email. So the emails get out slower and no images, plain text looks a lot more scammy to me and I assume also hurts conversions? Source: almost 3 years ago
  • Snov or Lemlist
    What about instantly.ai? Any experience around that? Source: about 3 years ago
  • Our first email ended up in the user's spam folder
    Yeah, well that's just how it works. You'll need to warm up your domain, there's a lot of ways to do it I would suggest something on the lines of https://instantly.ai/. Source: about 3 years ago

  • Our decision on Cursor following its acquisition by SpaceX
    Devin Automations is the most obvious one: solid UX, but can get very expensive to run. There are also a bunch of newer startups in this space. I'm building one myself, https://boxes.dev -- we're very early but building for this exact use case. Some other ones worth a look are Factory Droid and Amp Orbs. Those two build their own agent harness (like Cursor), whereas with boxes.dev we run the native codex and... - Source: Hacker News / 3 days ago
  • Mitchellh starts a new company: Superlogical
    These tools all assume you have machines to run the agents on. But for parallel agents I'm pretty convinced you want each agent on its own isolated devbox running your dev environment (not e.g. Worktrees on one box) - which isn't trivial to set up and manage. I'm working this with https://boxes.dev - a workspace for launching and managing claude + codex sessions, each running in its own cloud devbox. We launched... - Source: Hacker News / about 1 month ago
