Serverless vector database with REST APIs.
Upstash Vector is a serverless vector database from Upstash, the company known for serverless Redis and Kafka offerings. It follows the same pay-per-request pricing model that made Upstash Redis popular: you pay only for the operations you perform, with no minimum fees or idle costs. This makes it particularly attractive for applications with variable or unpredictable query patterns, such as AI agents that may go hours without queries then burst during active conversations.
The API is REST-based and designed for simplicity. You create an index specifying the embedding dimension and distance metric, then use upsert, query, and fetch operations. Each vector can carry a metadata payload for filtered search. Upstash provides SDKs for Python, TypeScript, and Go, plus a REST API that works from any HTTP client — including edge runtimes like Cloudflare Workers, Vercel Edge Functions, and Deno Deploy where traditional database drivers can't run.
CrewAI is an open-source Python framework for orchestrating autonomous AI agents that collaborate as a team to accomplish complex tasks. You define agents with specific roles, goals, and tools, then organize them into crews with defined workflows. Agents can delegate work to each other, share context, and execute multi-step processes like market research, content creation, or data analysis. CrewAI supports sequential and parallel task execution, integrates with popular LLMs, and provides memory systems for agent learning. It's one of the most popular multi-agent frameworks with a large community and extensive documentation.
