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. -

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. -

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. -

Haraka
A fast, highly extensible, and event driven SMTP server
Haraka is a highly scalable node.js email server with a modular plugin architecture. Haraka can serve thousands of concurrent connections and deliver thousands of messages per second. Haraka and plugins are written in asynchronous JS and are very fast. Haraka has very good spam protection (see plugins) and works well as a filtering MTA. It also works well as a MSA running on port 587 with auth and dkim_sign plugins enabled. Haraka makes no attempt to be a mail store (like Exchange or Postfix/Exim/Qmail), a LDA, nor an IMAP server (like Dovecot or Courier). Haraka is typically used with such systems. Haraka has a scalable outbound mail delivery engine built in. Mail marked as relaying (such as via an auth plugin) is automatically queued for outbound delivery. Haraka's plugin architecture provides an easily extensible MTA that complements traditional MTAs that excel at managing mail stores but do not have sufficient filtering. -

HTTP Server
A non-blocking HTTP application server for PHP based on Amp
This package provides a non-blocking HTTP/1.1 and HTTP/2 application server written in PHP based on Amp. Several features are provided in separate packages, such as the WebSocket component.

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. -

Centrifugo
Scalable real-time messaging server in a language-agnostic way
Centrifugo is language-agnostic. It's a standalone server with a simple API that integrates well with an application written in any programming language. No need to change an existing application architecture to introduce real-time features. Just add Centrifugo nearby and let it deal with persistent connections. Centrifugo is built in Go language with some smart optimizations inside. It has good performance – see a description of a test stand with one million WebSocket connections and 30 million delivered messages per minute with hardware comparable to one modern server machine. Many built-in features can help to build an attractive real-time application in a limited time. Centrifugo provides different types of subscriptions, hot channel history, instant presence, RPC calls. There is also the possibility to proxy WebSocket events to the application backend over HTTP or GRPC and more.
