Self-hosted vector database
Run ChromaDB on your own VPS in minutes.
Chroma gives your AI app a memory. Store docs, notes or support tickets as embeddings, and every user question pulls back the closest matching passages to ground your LLM's answer. That retrieval step is the core of any RAG chatbot, semantic search or agent memory. On your own VPS, ChromaDB runs as a persistent server that all your services can reach. Coolify installs it in one click, so you skip Docker Compose files, reverse proxy configs and manual container setup.
Because the server is yours, your vectors and source documents stay on a disk you control instead of in a shared SaaS index. Full root access lets you decide how Chroma is exposed. You can serve it over HTTPS on your own domain, require an auth token and allow only your backend in the firewall. Your RAG backend, a LangChain service or a workflow tool can run right next to it on the same machine.

FAQ
Frequently asked questions about Chroma
Answers to the most important questions before you start.
Yes. Chroma is open-source software under the Apache 2.0 license, so self-hosting it costs no license fee. With a Chroma VPS you only pay for the VPS. The price depends on the package (RAM, CPU, storage), the term – a longer term lowers the monthly price – and the location. Current package prices are shown live in the package section above.
- No license fee for Chroma
- You only pay for the VPS package
- Price depends on package, term and location
RAM matters most. Chroma keeps its vector index in memory, so the number of embeddings and their dimensions decide how much you need. Storage holds the persisted collections and your documents, and CPU handles indexing and queries. A smaller package works for prototypes. Large or high-dimensional collections need more RAM.
- More embeddings need more RAM
- Higher dimensions increase memory use
- Storage holds persisted collections
Order your VPS, open One-Click Apps in the panel and pick Chroma from the Coolify marketplace. Setup runs automatically, including the container, persistent volume and proxy, and Chroma is online within minutes. You don't need to write Docker Compose files or configure a reverse proxy by hand. One-Click Apps guide in the Help Center
- Pick Chroma in the One-Click Apps marketplace
- Coolify sets up the container and volume
- VPS online in 60 seconds
Yes. When your collections outgrow the available RAM or storage, you can move to a larger VPS package with more resources. Your panel shows the available upgrade options and their prices, so you only scale up when your data needs it.
- Scale RAM, CPU and storage
- Upgrade options shown in the panel
Your collections live in a persistent volume on your own VPS disk, not in a shared cloud index. Panel Backups and restores for your VPS are available with the ZapX Pass. You can also export the Chroma data directory yourself, for example with rsync to another server. Learn more about Backups

Turn on token authentication in Chroma and serve the API over HTTPS on your own domain via the Coolify proxy. Then allow access only from your app servers in the VPS network firewall. With the ZapX Pass, the ZapX AI Agent can suggest matching firewall rules and applies them only after you confirm. Firewall guide in the Help Center
- Token auth for the Chroma API
- HTTPS via the Coolify proxy
- Firewall rules for your app servers
You choose from our data center locations in Europe and America. Pick the one closest to your app servers and users to keep round trips short. Many North American teams start with Ashburn, Dallas or Los Angeles. You see the available locations when you configure your VPS.

Yes, you can cancel anytime in the panel. You pick a term when you order, and a cancellation takes effect at the end of the current term. Your Chroma server keeps running until then. How cancellation works

Why are my Chroma queries getting slower?
Let's check memory first. Chroma keeps its index in RAM, so if your collections have outgrown the available memory, the VPS starts swapping. I can show you current RAM usage and your largest collections, and then we can see whether a larger package makes sense.
