The HTTP Gateway for Postgres, Mongo, Elastic & Cassandra

Vaachas is a single HTTPS-based unified database gateway that sits in front of all your databases (Postgres, MongoDB, Cassandra, Elasticsearch) for backend applications. Your backend or serverless code sends one API request; Vaachas reads from and writes to the right databases in the order you specify, keeps them in sync for that call, and saves you from building queues, sync jobs, and custom glue code.
Hi Product Hunt! 👋
I’m Vivek. After building distributed systems at Amazon and Microsoft, I realized the hardest part of modern backend engineering isn't the logic—it's the Coordination.
We want the ACID guarantees of Postgres, but the flexibility of Mongo, the search power of Elastic, and the scale of Cassandra. But keeping them in sync requires building complex "Glue Services," queues, and fan-out workers.
Vaachas solves the "Dual/Multi Write" problem.
It is a Managed Gateway that sits in front of your existing databases. It gives you a single HTTP API to interact with all of them.
Key Capabilities:
Unified API: Query SQL (Postgres) and NoSQL (Mongo/Cassandra/Elastic) with one JSON syntax.
Coordinated Multi-DB Writes: Fan-out a single write across multiple databases in one request (e.g., insert into Users -> index in Elastic), with ordered sequences and clear status reporting.
Serverless-Friendly Connection Management: We manage pooled connections so your Lambdas and services don't overwhelm your databases.
Less Backend Boilerplate: Replace complex glue services with a thin API or serverless layer that calls Vaachas.
Who is this for? Vaachas is for teams running more than one datastore in production—Postgres + Elastic, Postgres + Mongo, or Postgres + Cassandra—who need a single place to coordinate writes and route reads. Typical users are backend / platform teams building search-heavy SaaS, analytics sidecars, or multi-tenant apps that have outgrown a single database.
We have a generous Free Tier (60 rpm) and Custom Plans for high-volume apps or apps with different needs.
I’d love to hear your feedback. How do you currently keep your Search Index in sync with your DB?
