Cachely is the managed self-hosted remote cache for Nx and Turborepo - the cache backend you'd otherwise build and run yourself, hosted for you on Cloudflare's edge (R2). It's a drop-in replacement for a DIY @nx/s3-cache / S3 bucket setup: point your build tool at Cachely with a token and two environment variables, and share build cache across CI and every developer's laptop.

Unlike a self-hosted cache, Cachely enforces read-only tokens at the API, so pull-request and fork builds can read but never write - closing the Nx cache-poisoning attack (CVE-2025-36852). It adds ROI reporting (the real build minutes and dollars the cache saved), per-tool insights, and build-optimization suggestions on top.

Pricing is a flat per-workspace subscription with no per-seat fees - add every developer, bot, and CI actor without watching the bill. Cachely never stores your source code; it caches only task outputs and their content hashes. Nx and Turborepo today; Bazel on the roadmap.

  • Entry level job trouble
    A SOC analyst role is not unrealistic if you are educated to masters level in computer science. It won't be a breeze, especially in the current climate, but you stand a fair chance if you are persistent and resilient. Make sure your resume is squared away and optimised for ATS parsing. Also, get some hands-on practice with the sort of tools and techniques a SOC analyst tends to use. There are some defense-focused... Source: about 3 years ago
