Tooling layer for Rust-based GPU kernel development

What to build

A starter-kit for Enki: a cargo-generate template plus a ready-made GitHub Action that builds, tests, and benchmarks GPU kernels written in stable Rust, aimed at individual Rust developers who want to try GPU compute without setting up CUDA or nightly toolchains.

Enki's Show HN proves there's curiosity about writing GPU kernels in stable Rust, but the project itself is too early to monetize directly — the opportunity is the glue layer (templates, CI, benchmarking) that makes it usable day one.

Demand

Rust developers and graphics/ML engineers who want GPU compute but are blocked by CUDA toolchain friction or nightly-only Rust GPU crates are the audience; timing is driven by the fresh Show HN post putting Enki in front of that exact crowd right now.

  Show HN: Enki – Write GPU compute kernels in pure stable Rust — 9 points, 1 comment on HN.

Stack

• Enki
• cargo-generate
• GitHub Actions
• Docker (GPU-enabled runner)
• Supabase (benchmark result storage)
• Cloudflare Pages (docs/playground site)

Solo + AI difficulty

The template and CI Action are a weekend build for one person with AI help — mostly config and docs work. The hard, slow part is a hosted playground: it needs real GPU-backed infrastructure to execute untrusted kernels safely, which is costly and non-trivial for a solo builder, so MVP should skip hosting and ship template+CI first (roughly 1-2 weeks), treating the playground as a stretch goal once Enki itself shows retained usage.

Entry threshold

Low capital barrier, but requires genuine Rust and GPU/compute knowledge to build credible tooling; a weekend MVP (templates, docs site) is feasible, but a differentiated paid product likely takes a few weeks of focused work.

Where to find first users

• Comment and follow up directly on the Enki Show HN thread and GitHub repo
• r/rust and r/GraphicsProgramming
• Rust GPU / compute Discord and Zulip channels
• A second, narrower Show HN post once the template+CI tool has its own repo

Counter-signals & risks

• GPU compute tooling is dominated by mature ecosystems (CUDA, wgpu, rust-gpu, Vulkan compute) with large existing user bases, making adoption of a new niche framework like Enki uncertain.

• Show HN traction alone (9 points, 1 comment) does not establish sustained developer demand or willingness to pay for add-on tooling; many Show HN projects see a one-time spike and no retention.

• Building a paid layer (profiling-as-a-service, template marketplace) requires Enki itself to reach critical mass and stability first, and the underlying project's long-term maintenance/roadmap is unverified from this signal alone.
