Upstash
Serverless Redis with per-request pricing. No connection limits, works at the edge. I use it for caching, rate limiting, vector search, and session storage in serverless apps.
Upstash provides serverless Redis and Kafka with per-request pricing. There are no connection limits, and it works natively at the edge - making it a natural fit for serverless and edge-first architectures.
I use Upstash for caching, rate limiting, vector search, and session storage in serverless applications. Traditional Redis requires persistent connections, which doesn't work well with serverless functions that spin up and down. Upstash solves this with an HTTP-based API that works anywhere.
The pricing model is straightforward - you pay per request rather than for provisioned capacity. This makes it cost-effective for applications with variable traffic. They also offer QStash for message queues and Upstash Vector for vector similarity search, which rounds out the serverless data layer.
Other Data tools
Metabase
Open-source BI and data visualisation. Build dashboards, run ad-hoc queries, and share insights without writing SQL. Works well with Postgres, MySQL, and more.
Supabase
Hosted Postgres with auth, storage, and realtime. Open-source Firebase alternative. I use it for backend-as-a-service and vector search via pgvector when I need a database without managing servers.
