All-TypeScript reactive backend platform integrating databases, functions, workflows, sync, and search
About Convex
Convex is a reactive backend platform, as the vendor positions it, bringing database, functions, workflows, sync, search, and file storage into a single platform, labeled All TypeScript, zero glue (no extra glue layer). Officially it provides ACID transactions, so concurrent writes never corrupt data, and it works well with any model, any agent, and any editor. Plans start at $0 and are officially said to cover personal projects and startups, with another plan at $25 per developer/month and a Business plan with a $2,500/month minimum on the enterprise pricing page.
