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.

Listmonk is fantastic -- I use it for the newsletter of my own blog and am amazed by how simple it was to set up and how easy it is to operate and use every time I send out a newsletter. Prior to Listmonk I used Mailtrain[0] and like Listmonk so much I want to run it as a service (with 30% donated back to the Listmonk project of course) -- deliverability worries and initial setup aside it's just the kind of... - Source: Hacker News / almost 5 years ago
