WebMerge is now Formstack Documents — and still costs $92/mo

The Best WebMerge Alternative That Actually Costs Less

Magic Decoder does everything WebMerge did — fill templates, generate documents, download instantly — with zero merge tags, zero configuration, and a free plan.

No credit card. No merge tags. No setup.

What happened to WebMerge?

WebMerge was acquired by Formstack in 2018 and rebranded as Formstack Documents. The product still exists, but prices jumped significantly — plans now start at $92/month. Many longtime WebMerge users have been searching for a simpler, more affordable replacement ever since.

The core problem with WebMerge — and Formstack Documents today — is that you have to manually add merge tags to every document. That means editing your Word template to add {{client_name}}, {{project_date}}, and so on throughout every template. It's tedious, error-prone, and breaks whenever someone edits the document.

Magic Decoder fixes this entirely. Upload your template exactly as it is — no tags, no special formatting. AI reads the document and figures out the fields automatically.
