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.

We started with a simple canvas and turned it into a fully collaborative whiteboard. Along the way, we added real-time cursors, presence, comments, notifications, and even voice huddles using Velt. Instead of building sync logic and infra from scratch, we used Velt MCP and agent skills to handle the heavy lifting and get everything working quickly. - Source: dev.to / 3 months ago
Velt is a collaboration SDK that lets you add real-time features like comments, presence, and notifications directly into your product. Instead of building backend infrastructure for multi-user sync, conflict resolution, and event handling, you integrate Velt components and ship collaboration features in days. - Source: dev.to / 3 months ago
Velt lets you skip all of that. You plug it into your app and get comments, presence, notifications, and shared context immediately. You donโt worry about syncing users or handling concurrent updates. Your code stays focused on the UI and user experience, not real-time infrastructure. - Source: dev.to / 3 months ago
Velt: Velt is the key piece. Instead of building real-time infrastructure ourselves, Velt provides presence, comments, notifications, and collaboration out of the box. Once integrated, features like reactions, read status, and threaded comments work automatically without writing extra backend or real-time code. - Source: dev.to / 4 months ago
We built PixFrame, a Canva-like design editor, to see what that looks like in practice. This article explains how the collaboration layer is built, including CRDT sync, live cursors, presence, and comments. We used Velt for the collaboration layer and the Velt Plugin to set it up quickly. - Source: dev.to / 4 months ago
