Cachely.dev

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.

You kind of can do this already with a raspberry pi strapped to the back of a monitor and "barrier", the successor to synergy, to use the keyboard and pointing device of your laptop on as many displays on the same desk as you want. Each one is an independent computer. https://github.com/debauchee/barrier. - Source: Hacker News / about 1 month ago
I used to and still do use and recommend Barrier for sharing a mouse and clipboard and keypresses across OS's. It works for Mac, Windows, and Linux. They have a fork input-leap... It doesn't work, and there is a paid on from the same original developers called Synergy that works well too. - Source: dev.to / almost 2 years ago
