Azure DevOps

  • First 5 users free applies to Basic plan only; Test Plans users are not included in free tier
  • Storage pricing increases per-GiB cost as volumes grow, with no volume discount threshold below $0.25

Preact

  • Compatibility through preact/compat is good but not total, and some React libraries break in ways that are hard to diagnose
  • Behavioural differences from React exist in edge cases, particularly around event handling
  • A much smaller community, so unusual problems have fewer existing answers than React

Preact: Is Preact free?

Yes, open source under the MIT licence.

Azure DevOps: Is there a free tier for Azure DevOps?

Yes, Azure DevOps includes 5 free users on the Basic plan. Additional free allocations include 1,800 free minutes per month on Azure Pipelines with a free parallel job, 2 GiB free storage on Azure Artifacts, and free access for Visual Studio subscribers and Stakeholders with limited functionality.

Source
Preact: Can I use React libraries with Preact?

Most, through the preact/compat layer. Compatibility is good but not complete, so libraries relying on React internals can break.

Azure DevOps: What does the Basic + Test Plans tier add to Azure DevOps?

The Basic + Test Plans tier adds test planning and execution capabilities, browser-based testing, and centralized reporting features. This tier costs $52 per user per month compared to $6 per user for the Basic plan.

Source
Preact: Why choose Preact over React?

Bundle size, almost always. If payload is not a binding constraint, React’s ecosystem is usually the better trade.

Azure DevOps: How is Azure Artifacts priced?

Azure Artifacts provides 2 GiB of free storage, then charges $2 per GiB for 2-10 GiB, $1 per GiB for 10-100 GiB, $0.50 per GiB for 100-1,000 GiB, and $0.25 per GiB for over 1,000 GiB.
