About wafer

wafer is a GPU development stack that lives inside your IDE, combining profiling, a compiler explorer, and GPU documentation in one place. It aims to reduce the need to switch between an editor, profiler, browser docs, and external compiler tools when writing GPU kernels.

Review

wafer focuses on developers who write and optimize GPU kernels and want faster feedback loops without leaving their editor. By bringing profiling, compiler exploration, and documentation into the IDE, it addresses a common friction point in GPU development workflows.

Key Features

• Integrated profiling tools directly inside the editor to inspect performance hotspots.
• Built-in compiler explorer for comparing generated code and compiler output without switching apps.
• In-editor GPU documentation and reference material for quick lookups while coding.
• Unified editing experience that reduces context switching between multiple developer tools.

Pricing and Value

wafer is listed as Free at launch. The core value proposition is time saved and fewer interruptions during kernel development: bringing profiling, compiler insights, and docs into a single environment can speed iteration and make performance tuning more approachable. For teams or individuals focused on GPU kernel work, that consolidation can translate into meaningful productivity gains even if advanced or enterprise features are added later.

Pros

• Keeps editing, profiling, and compiler exploration within the IDE for a smoother workflow.
• Helpful for developers who regularly write and tune GPU kernels.
• Free at launch, which lowers the barrier to trying it out.
• Reduces the number of tools and browser tabs needed during optimization tasks.

Cons

• Primary focus is on GPUs at launch, with broader backend support (TPUs/NPUs) not yet available.
• As a newly launched product, some integrations or advanced features may be missing compared with mature toolchains.
• Reliance on editor extension model may limit workflows for teams that use dedicated external profiling suites.

Overall, wafer is most useful for GPU kernel developers, performance engineers, and researchers who want faster in-editor feedback when optimizing code. Developers who primarily work on non-GPU projects or require extensive external tooling may find it less essential until additional backends and integrations are added.
