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.
Swapstack is the self-serve newsletter marketing platform that lets you sponsor countless independent newsletters (like Flipboard) without the added stress of emails and logistics.
Choose between a CPA or PPC model and work with up to 1,000 publishers at once! Plus, enjoy a streamlined sponsorship process that eliminates back-and-forth with the publisher, making it a win/win for both sides and getting your sponsorships out in the world with minimal turnaround time.
For brands, Swapstack makes it easy to create custom sponsorships and connect with publishers via a simple chat box. And for publishers, Swapstack lets you monetize your work and connect with sponsors, whether you're looking for immediate opportunities via the affiliate network, the PPC tool or more bespoke arrangements, Swapstack facilitates it all.
Sponsorships can either be one-off, recurring or always on depending on the approach you take. For maximum exposure, a combination of CPA and PPC tools are recommended!
With 60 million audiences and 1,000+ publishers, Swapstack's innovative ad-tech is a win-win for everyone!
Pricing: Swapstack operates on a paid-first policy so while it's free to browse, any sponsorships that happen will incur a small %-based fee of the final spend.

I recommend using something like Swapstack (https://swapstack.co/) to get infront of the targeted audience instead of Google Ads. They also have Plug & Play feature where you have to only pay the writer for the clicks and conversions they got for you. Highly recommend that! Source: almost 5 years ago
