Show HN: Elestio – Managed platform for over 150 open-source software stacks
Hello Hacker News! We're Joseph, Kieran and David from elestio (<a href="https://elest.io/" rel="nofollow">https://elest.io/</a>).
We've built a platform that offers open-source software as a managed service - we take care of the OS and app updates, security, SSL, networking, backups, the whole deal.<p>In 2009, we started deploying open-source software for websites and web apps we built, many for SMB and enterprise customers. Our process was basically: spin up VM's from a hosting provider, install the software we needed, then update it manually / when it was needed / critical, etc.<p>Once we hit > 100 servers/services needing updates, backups, capacity monitoring and alerting, etc. we saw that it was getting totally unmanageable… so we built what would eventually become elestio.<p>We've put a lot, a lot, a lot of work into building something that allows us (and now you) to deploy a new service in just a few minutes, with zero ongoing maintenance / devops overhead. We basically turned open-source software into a SaaS experience.<p>We update all the apps, respecting SemVer on the branch you select, issue and renew SSL certs automatically (even for your own domains, for free), automatically implement a 3-2-1 backup strategy, caching is handled and we put your service behind a configurable firewall and rate limiter with sane defaults. We have implemented Nebula to connect your services hosted in different datacenters across regions and providers as if they were on the same network and Borg backups to do deduplicated incremental backups in a remote datacenter.<p>There were many challenges in building it… VM providers don't have homogenous or feature-complete APIs for provisioning servers, we tested 6 different mesh networking/VPN solutions to enable services running in different datacenters, regions, or providers to connect to each other securely, and we did a lot of work to create a sane templating system that covers setup, security, backups, upgrade, migrations and monitoring, lots of work to test the safest ways to update OS and apps without breaking things… but we got there and it works really well (we think)! Deployments are based on Docker, which helped a lot to standardize everything.<p>We've been using it to deploy and maintain over 12,000 services for our own enterprise clients and we've spent the last year making it user-friendly (and even more bulletproof for end-user configs). Elestio can currently deploy any one of over 150 open-source software stacks like Postgres, MySQL, OpenSearch, Redis, Wordpress, NodeBB, Jitsi, Uptime-kuma, Plausible, GitLab,, Strapi, Ghost, or even PowerDns, Grafana, ClickHouse, etc. in about 3 minutes, flat.<p>We currently support AWS Lightsail, Linode, Hetzner, Vultr and Digital Ocean, and BringYourOwnVM, if you want to run on your own provider account or even on-premise but have all the features of managed services. We are offering 1 BYOVM service per customer for free forever.<p>Something we really wanted to do was make sure we were part of a healthy open-source ecosystem. To that end, elestio will donate part of all revenue to the open-source projects our customers are using. We will review this annually and if it's possible to increase it, we will. This is a win-win-win to us. Open-source developers and communities get more resources to improve their software while our customers, our staff and other stakeholders know that they are helping to support the open-source community.<p>For this launch we made a partnership with DigitalOcean, they are offering $250 of free credits on Elestio if you go through this link: <a href="https://try.digitalocean.com/elestio/" rel="nofollow">https://try.digitalocean.com/elestio/</a><p>Alternatively you can also register here and get $20 of free credits but not limited to DO infrastructure: <a href="https://dash.elest.io/signup" rel="nofollow">https://dash.elest.io/signup</a><p>All your questions and comments are welcome and if you want to share any devops horror stories, please do! We're giving out free credits for the best ones!!<p>Joseph, Kieran and David

Show HN: Supernotes 2 – a fast, Markdown notes app for journalling and sharing
Hi HN – we first launched Supernotes[1] to HN in April 2020, and since then Tobias and I (it's just the two of us) have put in the work to make what we hope is an amazing note-taking app. Although the note-taking / personal knowledge management landscape is <i>incredibly</i> competitive at the moment (with lots of great apps adding great new features every day), we think that with the newly released Supernotes 2 we're keeping pace and delivering a unique and satisfying knowledge management experience.<p>Here's the combination of features that make us stand out:<p>- a powerful markdown-based notecard system that is simple/beautiful but also super flexible<p>- a WYSIWYM[2] editor that keeps markdown marks for explicitness while still giving you a preview of what the content looks like when rendered<p>- eschewing a folder system in favor of multi-parent nested hierarchies<p>- unique collaboration system that is optimized for granular sharing between individuals rather than "all-in" sharing amongst teams or specific groups<p>- notes that can be linked both with inline bidirectional links or the aforementioned hierarchies, allowing you to build (and <i>experience</i> with our 2D and 3D graph views) a robust graph of your knowledge<p>There are of course tons of other cool features that are included as well, but those are the highlights. If any of that sounds interesting to you, you can sign up here[3] – we would love to hear any feedback you might have!<p>[1] <a href="https://supernotes.app/?ref=hn" rel="nofollow">https://supernotes.app/?ref=hn</a><p>[2] <a href="https://en.wikipedia.org/wiki/WYSIWYM" rel="nofollow">https://en.wikipedia.org/wiki/WYSIWYM</a><p>[3] <a href="https://my.supernotes.app/entry?signup=1&ref=hn" rel="nofollow">https://my.supernotes.app/entry?signup=1&ref=hn</a>

This post shows and explains the design of the eBike I built myself. I decided to post it on this specific forum because this is where it all started, by stumbling on another post, as mentioned in my entry.
