What's free from MongoDB
MongoDB for Startups · Startup program
Startups under 7 years old at Series A or earlier receive tiered MongoDB Atlas credits, Voyage AI tokens, technical support, and go-to-market benefits across four stage-based tiers.
The catch: Promo codes must be activated within 12 months and credits expire 12 months after activation; codes apply only to future charges, not past usage.
- 12 months to activate the promo code
- 12 months to use Atlas credits after activation
- Promo codes apply only to future charges, not past usage
- Base tier: less than 7 years old and Series A or earlier
- Single software product; dev shops and agencies not eligible
- Developer Support free for first 30 days, then from $49/month (payable with startup credits)
Voyage AI Free Embedding and Reranking Tokens · 200,000,000 tokens
Voyage AI by MongoDB includes a free tier for every account: 200 million free tokens on most current embedding and reranking models, 50 million on specialized models, and 200M text tokens plus 150B pixels on multimodal models.
The catch: Without a payment method you are held to 3 requests and 10K tokens a minute; the published 2,000 RPM limits need a card on file (Usage Tier 1). Older model generations get no free tokens.
- 200M free tokens each: voyage-4-large, voyage-4, voyage-4-lite, voyage-code-4, voyage-context-4, rerank-3, rerank-3-lite
- 50M free tokens: voyage-finance-2, voyage-law-2, voyage-code-2
- voyage-multimodal-3.5: 200M text tokens and 150B pixels
- No free tokens for older models (voyage-3.x, voyage-context-3, voyage-multimodal-3, rerank-2.x)
- Without a payment method: 3 RPM and 10K TPM (free trial rate limits); adding one moves you to Usage Tier 1, where the free tokens still apply
MongoDB Atlas Free Cluster (M0) · 0.5 GB
MongoDB Atlas gives every project one free-forever M0 cluster with 512 MB of storage on AWS, Azure or Google Cloud, and Atlas Vector Search works on it with up to 3 search or vector indexes.
The catch: 512 MB covers documents plus indexes, throughput is capped at 100 operations per second, there are no backups, and the cluster is paused after 30 days with no connections.
- 1 free M0 cluster per project: 512 MB storage (documents plus indexes), shared RAM and vCPU
- Up to 3 search or vector indexes
- 100 operations per second, 500 connections
- 10 GB in and 10 GB out per rolling 7 days
