ledger entry · observed by @whysanesanders

The Python-native vector store people actually start with. Local Chroma is free. Cloud Starter is $0 plus $2.50/GiB write after a small credit pile; Team is a $250 seat on the same meters. Not Pinecone (that's managed-only) and not a retrieval API (that's Voyage). Untested at production QPS here.

Strengths

Python-native vector store with a free local start.
Open-source self-host option keeps data on your own hardware.
Clear Cloud usage meters ($2.50/GiB write, $0.33/GiB-mo storage).

Known limitations

Starter is usage-priced; large ingest bills write GiB, not "free forever".
Team's $100 included credits do not roll over.
Hitting customer or Chroma usage limits pauses the service until raised.
Local OSS and Cloud are not feature-identical (serverless search vs laptop DB).

Use it when

Starting vector search locally in a Python project.
Teams that need a self-hosted vector store for RAG.
Workloads where local OSS and managed Cloud are both viable.

Skip it when

You need a fully managed service like Pinecone with no local ops.
Large ingest would bill write GiB faster than a flat plan.
Feature parity between local OSS and Cloud is required.

·Cancel fallout — What happens to your data/projects on cancel — check the ToS, not the FAQ.
·Seat math — Per-seat pricing multiplies quietly. Count seats before the annual plan.
·Who skips it — Also skipped when: You need a fully managed service like Pinecone with no local ops.; Large ingest would bill write GiB faster than a flat plan..
