An Enterprise Tried for Years to Pay for LanguageTool and Run It on Its Own Servers

A discussion about Grammarly's cancellation flow on Hacker News took the turn these discussions usually take. The thread, opened on 23 September 2026 under the headline "Grammarly will send unhinged messages to all your users if you try to cancel", drew 388 points and dozens of replies from people comparing notes on what they use instead. One comment asked the plain version of the question: does anybody actually have a good alternative?

The most concrete answer came the next day, from a user who runs an open-source grammar checker inside a corporate network and has spent years trying to buy a subscription for it - on the customer's terms rather than the vendor's. The comment is reproduced below in full.

It depends on what you mean by "good alternative".

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.

It's also devoid of AI/LLM bullshit for writing. Spelling and grammar rules, a few notes about long sentences, that's it.

However, LanguageTool nerfs their other plugins (like mail plugins) to require a subscription service. I've pleaded with them for years to please allow me to pay a subscription price but use our internal server simply because we don't want/need a spelling/grammar tool to send content to the cloud. We don't want free. We want private.

The odd thing is that the official LanguageTool browser plugins DO allow use of a self-hosted LanguageTool server; clearly it's doable. There's a poorly maintained obsidian plugin that also works(ish). But that's about it. We live with these limitations.

What the comment describes

LanguageTool is a free and open-source grammar, style and spell checker; the project sells a proprietary "Premium" service alongside it under an open-core model. Its server can be run by an organisation on its own hardware, which is what the commenter's team does: a containerised deployment in a private cluster, reachable only from the corporate network or over VPN.

The complaint is not that the software costs too much, or that the free tier is too limited. It is that the parts the team wants to pay for - the surrounding integrations, and the convenience of a supported subscription - are only sold in a form that routes their text through someone else's cloud. The commenter points out that the official browser extensions already accept a self-hosted server, so the restriction reads as a packaging decision rather than a technical limit.

Why it is worth reading closely

Subscription fatigue is usually reported as a price story: too many services, too much per month, cancellation flows designed to wear you down. This comment is the same complaint with a different mechanism. The buyer is willing to pay the asking price and is still blocked, because the thing on sale is a deployment model the buyer cannot accept. The constraint is privacy, not budget.

For anyone packaging software for companies, that distinction has a practical edge. "We don't want free. We want private." is a one-line description of a customer segment that a cloud-only price list cannot reach at any discount.

What this is not

This is one account, from one commenter, describing one organisation's procurement experience. We have not independently verified it, and it is not a survey: it shows that a shape of demand exists, not how common it is. The vendor's side is not represented here.
