Launch HN: LayerCI (YC S20) - Staging servers that act like (and replace) CI Hi HN, Lyn & Colin here. We’re co-founders of LayerCI (https://layerci.com), which gives you a modern DevOps experience (CI/CD & staging environments) with as little work as writing a Dockerfile. Most teams need CI/CD (run the build and deploy every time a developer pushes) or staging (host a server with my app in it to share), but current approaches always have at least one of these problems: - Simplistic (only run unit tests) - Slow (wait 10 minutes to run the same repetitive setup steps like "npm install") - Complex (cache keys, base images, a slack channel to reserve staging servers, …) We’ve spent over a year iterating with our customers to build a product that solves all of these problems. Our configuration files (Layerfiles) look like Dockerfiles, so regular developers can write and maintain them. Here's one that creates a staging server for create-react-app: FROM vm/ubuntu:18.04 RUN curl -sS https://ift.tt/2mHHfki | sudo apt-key add - && curl -fSsL https://ift.tt/2jJProL | bash && apt-get install nodejs python3 make gcc build-essential COPY . . RUN npm install RUN npm test RUN BACKGROUND npm start EXPOSE WEBSITE http://localhost:3000 We charge a flat $42/mo/developer on our paid plan. Because it's a flat fee and not usage based, we're incentivized to make things as fast as possible: Our current margins come from a custom-built hibernating hypervisor that lets us avoid running "npm install" thousands of times per day. We’ve upgraded the free tier to 5GB of memory for new installations this week. It’s perfect for personal projects or small MVPs where you’d like a powerful demo server that will build on every push and automatically hibernate when it’s not being used. The easiest way to try out LayerCI is to follow our interactive tutorial: https://layerci.com/ or look at the docs: https://ift.tt/3cpAFfF We would love to hear your thoughts about CI/CD, staging, and what we’ve built!

Show HN: Tape It, iOS recording app for musicians Hello HN, Over the last 15 months, two friends and I developed the music recording app we felt we wanted based on our own needs as musicians. It's called Tape It [1] and has just recently hit the Apple App Store [2]. We put a lot of effort into a good UX to help musicians really focus on playing their instrument instead of pretending to be a recording engineer. The app records in stereo on newer iPhones (although that's a premium feature; the free version only records in standard mono audio quality). I would be really grateful for advice from this community on how to best approach marketing. We had a great TechCrunch article covering our launch [3], and we posted it on various music websites. Turns out advertising on Google or Apple Search is a dark art, though. We have some good ideas for developing a good social media presence, but they will take time. Please hit us with feedback, opinions and advice that you think a young ind...
