Free Pinecone Alternatives
Pinecone’s free Starter plan against seven verified free vector databases - Qdrant, Zilliz, Supabase, Neon, Upstash, Cloudflare and MongoDB - with limits.
Esta sección está en inglés.
Pinecone’s free Starter plan is a good default - 2 GB of serverless storage across 5 indexes, with monthly read and write units - but it is one project in one region (AWS us-east-1), with community support only, and past the free units you move to Builder or Standard. Every alternative trades something else: Qdrant and Zilliz give a dedicated free cluster but pause or cap it; Supabase, Neon and MongoDB put vectors next to the rest of your data; Upstash and Cloudflare Vectorize are serverless and cheap to leave idle. This page lines up Pinecone’s own plan against seven verified free options, using the same data as the free AI coding tools directory, each re-checked monthly. The free vector databases guide walks the choice step by step.

Preguntas frecuentes
Esta sección está en inglés.
- Is Pinecone free?
- Yes, the Starter plan: one project with up to 2 GB of serverless vector storage across 5 indexes, 1M read units and 2M write units a month, and 5M free tokens a month on its hosted embedding models, with no card. It runs on AWS us-east-1 only; beyond the free units you upgrade to Builder ($20 a month flat) or Standard ($50 a month minimum).
- What is the best free alternative to Pinecone?
- For the most space, Zilliz: 5 GB of managed Milvus, about 1M 768-dimension vectors. For the simplest swap, Qdrant: a free-forever 1 GB-RAM cluster that serves about 1M 768-dimension vectors. If your app already needs a database, Supabase or Neon give you pgvector inside Postgres at no cost.
- Do any free vector databases delete my data when idle?
- Several pause or remove idle projects. Supabase pauses a free project after a week of inactivity, Qdrant suspends an unused cluster after a week and deletes it after four weeks, and MongoDB Atlas pauses an M0 cluster after 30 days without connections. Check the catch on each row before you rely on one.
- Do these Pinecone alternatives need a credit card?
- No - none of the eight rows asks for a card. Upstash moves your index to pay-as-you-go if you add one, so leave it off if you want a hard cap.
- How current is this comparison?
- Every row is generated from the aifree.dev catalog, whose offers are re-checked monthly. Vector database allowances shift quietly, so a row changes or disappears when the vendor does.
