Help everyone understand complex systems using lightweight and interactive visuals. IcePanel helps technical and non-technical people model their software architecture in a simple and structured way using the C4 model. Create diagrams at different levels of detail, from high-level to low-level, that connect to your code. Tell dynamic stories about your architecture using Flows and Tags to help onboard new team members, or evaluate key user journeys.
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.

For the architectural documentation like this one, the C4 Model [0] is a much better fit than UML - primarily because it's less rigid in notation and modeling components. And in terms of tooling, I find IcePanel [1] to have the right combination of flexibility and simplicity. [0] https://c4model.com/ [1] https://icepanel.io/. - Source: Hacker News / over 1 year ago

I use UML quite a bit but it's never really what I'm after, somnething more modern and fluid and gui driven that more people can use. Icepanel [1] looks really cool but I haven't tested it and I'm not sure it really fits my use case. It seems like it's mostly for api driven rpc/grpc/rest services when I kind of want to use it to visualize backend/infra/terraform sort of things. Might be interesting to you.

1. We started using https://icepanel.io/ for microservices, Software, anything thats documentable for later read. 2. More diagrams, less key strokes 3. We have dedicated page owners on confluence, its mix of engineers, leaders, PM's, QA etc. - Source: Hacker News / over 2 years ago
