What we found

01
LanguageTool
github.com

A self-hostable grammar checker; one team calls its private on-prem server reliable.

Source discussion: Grammarly will send unhinged messages to all your users if you try to cancel

We use a self-hosted OSS LanguageTool server that's containerized and runs in a private, on-prem cluster to provide good performance and be HA, but it only works on our corporate network or when using a VPN connection while roaming/remote. It's incredibly reliable.

Mastra
mastra.ai

A TypeScript framework for building agents; one evaluator preferred its more complete offering.

Source discussion: Strands Harness

I looked into it and ended up picking mastra as it had a better story / seems more complete for people making agents in typescript.
