If you're looking for another Jetboost alternative, NocodeCMS is worth a look. This low-code, free, open-source CMS is positioned somewhere between collaboration and control over Webflow CMS data. It's got an Airtable-like interface, direct image publishing, and 35+ field types, including Markdown and open AI-generated text. It doesn't suffer from Webflow CMS limits on items and collections, and it's got powerful collaboration abilities, too, which is why it's a good option for designers and non-technical people.
Another contender is Meilisearch, an open-source search engine that delivers fast, relevant results and supports search-as-you-type. Meilisearch is designed to be easily integrated into websites and apps, with support for filters, language detection and custom relevance. It's also got strong security options and flexible pricing, so it's a good option for adding search capabilities to your Webflow site.
These tools can help you add advanced features to your Webflow site even if you don't know how to program, which is why they're good for designers and non-techies who want a powerful CMS and search.
