Vaultwarden
Bitwarden compatible server written in Rust
Basically full implementation of Bitwarden API is provided including organizations support, attachments, vault API support, serving the static files for Vault interface, website icons API, authenticator and U2F support, yubiKey and Duo support. Pull the docker image and mount a volume from the host for persistent storage. This will preserve any persistent data under /vw-data/, you can adapt the path to whatever suits you. Some web browsers, like Chrome, disallow the use of Web Crypto APIs in insecure contexts. In this case, you might get an error like Cannot read property 'importKey'. To solve this problem, you need to access the web vault from HTTPS. This can be configured in vaultwarden directly or using a third-party reverse proxy (some examples). If you have an available domain name, you can get HTTPS certificates with Let's Encrypt, or you can generate self-signed certificates with utilities like mkcert. Some proxies automatically do this step, like Caddy. -

webhook
webhook is a lightweight incoming webhook server to run shell commands
webhook is a lightweight configurable tool written in Go, that allows you to easily create HTTP endpoints (hooks) on your server, which you can use to execute configured commands. You can also pass data from the HTTP request (such as headers, payload or query variables) to your commands. webhook also allows you to specify rules which have to be satisfied in order for the hook to be triggered. For example, if you're using Github or Bitbucket, you can use webhook to set up a hook that runs a redeploy script for your project on your staging server, whenever you push changes to the master branch of your project. If you use Mattermost or Slack, you can set up an "Outgoing webhook integration" or "Slash command" to run various commands on your server, which can then report back directly to you or your channels using the "Incoming webhook integrations", or the appropriate response body. -

Telegraf
The plugin-driven server agent for collecting and reporting metrics
Telegraf is an agent for collecting, processing, aggregating, and writing metrics. Design goals are to have a minimal memory footprint with a plugin system so that developers in the community can easily add support for collecting metrics. Telegraf is plugin-driven and has the concept of 4 distinct plugin types. Input Plugins collect metrics from the system, services, or 3rd party APIs. Processor Plugins transform, decorate, and/or filter metrics. Aggregator Plugins create aggregate metrics (e.g. mean, min, max, quantiles, etc.). Output Plugins write metrics to various destinations. New plugins are designed to be easy to contribute, pull requests are welcomed and we work to incorporate as many pull requests as possible. You can try Telegraf right in your browser in the Telegraf playground. Telegraf shares the same minimum requirements as Go. -

omnisharp-roslyn
OmniSharp server (HTTP, STDIO) based on Roslyn workspaces
OmniSharp is a .NET development platform based on Roslyn workspaces. It provides project dependencies and C# language services to various IDEs and plugins. OmniSharp is built with the .NET Core SDK on Windows and Mono on OSX/Linux. It targets the net472 target framework. For platforms other than Windows, OmniSharp ships with an embedded Mono which is based on version 6.12.0, includes MSBuild 16.8.0 and is provisioned during the build script. If Mono is globally installed on the system, OmniSharp will prefer it over the embedded version, however version >=6.4.0 is required (the lowest version with at least MSBuild 16.3.0). For Arch Linux users, you need package mono-msbuild (>= 16.3). In addition, if you need the HTTP interface and you want to run on Linux, you'll also need to make sure that you have libuv installed. -

Cheerio
Implementation of core jQuery designed for the server
Fast, flexible & lean implementation of core jQuery designed specifically for the server. Cheerio implements a subset of core jQuery. Cheerio removes all the DOM inconsistencies and browser cruft from the jQuery library, revealing its truly gorgeous API. Cheerio works with a very simple, consistent DOM model. As a result parsing, manipulating, and rendering are incredibly efficient. Cheerio wraps around parse5 parser and can optionally use @FB55's forgiving htmlparser2. Cheerio can parse nearly any HTML or XML document. Cheerio parses markup and provides an API for traversing/manipulating the resulting data structure. It does not interpret the result as a web browser does. Specifically, it does not produce a visual rendering, apply CSS, load external resources, or execute JavaScript. If your use case requires any of this functionality, you should consider projects like Puppeteer or JSDom. -

Engine.IO
Transport-based cross-browser bi-directional communication layer
In most cases, the connection will be established with WebSocket, providing a low-overhead communication channel between the server and the client. Rest assured! In case the WebSocket connection is not possible, it will fall back to HTTP long-polling. And if the connection is lost, the client will automatically try to reconnect. Scale to multiple servers and send events to all connected clients with ease. Socket.IO is a library that enables real-time, bidirectional and event-based communication between the browser and the server. There are also several client implementation in other languages, which are maintained by the community. The client will try to establish a WebSocket connection if possible, and will fall back on HTTP long polling if not. WebSocket is a communication protocol which provides a full-duplex and low-latency channel between the server and the browser. -
