Connect-rust is a Tower-based implementation of the ConnectRPC protocol, including support for handling gRPC and gRPC-Web requests, and JSON/binary encoded messages, all from the same handler, as the ConnectRPC specification intends. Unary and all three streaming RPC types (client streaming, server streaming, and bidirectional) are supported for both clients and servers. The client transports can use HTTP/1.1 and HTTP/2, with or without TLS as appropriate.

Project mention: Building an LSP Server with Rust is surprisingly easy and fun | dev.to | 2026-04-06
For LSP with Rust there are several choices. The most popular one is tower-lsp, but unfortunately that project hasn't been updated in about three years. There isn't much activity around the alternatives either; LSP is kind of a niche thing. For this post, we'll use tower-lsp-server, a community fork of tower-lsp that's actively maintained.

Project mention: The Rise of Hybrid PHP: Blending PHP with Go and Rust | news.ycombinator.com | 2025-08-30
Pasir is like frankenphp, but in Rust. Very promising, but still early in development:
https://github.com/el7cosmos/pasir
Which uses the following Zend API bindings for Rust:
https://github.com/davidcole1340/ext-php-rs
There's also all sorts of interesting experiments, like ngx-php, which basically embeds PHP via Zend API inside an nginx binary: https://github.com/rryqszq4/ngx-php
And workerman, which has a hybrid backend of asio libraries, so you can get pretty fast runtimes: https://github.com/walkor/workerman
