Letta Hosting Live In 5 Minutes

Deploy Letta hosting and run a self-hosted stateful AI agent server whose memory persists across sessions, secured with a generated API password from the first boot. xCloud configures the pinned Letta 0.16.8 image, a private Postgres database with pgvector, persistent storage and the HTTPS reverse proxy in minutes. There is no web interface in the server image: you call the REST API or point a client at it.

What is Letta?

Self-hosted Letta, formerly MemGPT, is a platform for building AI with advanced memory that can learn and self-improve over time. Its README describes a full-featured agents API with Python and TypeScript SDKs, memory blocks, tools and model-agnostic agents, and a separate Letta Code command-line tool. This template deploys the server, a REST API backed by Postgres with pgvector, in place of a hosted agent platform, under the Apache-2.0 licence.

On xCloud the template runs the Letta 0.16.8 server image beside a private pgvector Postgres database, both pinned by immutable digest, with letta_db and letta_data volumes. HTTPS is published on your domain behind a generated API password. There is no in-image web UI, and only Letta's free hosted model works until you add your own provider key.

From Sign-Up to a Live Letta API In Just 3 Easy Steps

Self-hosting Letta normally means a private Postgres database with pgvector, a generated API password, a domain and a certificate before an agent can hold a memory. This is the same result without assembling any of it.

Step 01
Sign Up
Create your xCloud account and pick Letta from the OneClick catalog. Choose a domain — the template needs no other app-specific fields.
Step 02
We Deploy It For You
One click. We bring up the pinned Letta image alongside a private Postgres (pgvector) database, generate an API password, and publish the Letta REST API over HTTPS on your domain.
Step 03
Connect A Client And Create An Agent
Wait a few minutes for first-boot migrations, then point a Letta SDK client at your API URL with the generated password as a bearer token, or attach the hosted ADE at app.letta.com, and create your first agent.

Everything Letta Does, On Your Own Server

Letta runs in full here — the same stateful agent server as any hosted agent-memory platform, on infrastructure you control.

Stateful Agents With Persistent Memory
Build AI agents whose memory survives across sessions, backed by Postgres with pgvector rather than an ephemeral in-process store.
Secure From First Boot
A generated API password is required on every route except the health check — unauthenticated and wrong-token requests are refused.
SDK Or Hosted ADE
Connect any Letta SDK client, or attach the hosted Agent Development Environment at app.letta.com pointed at your own API URL.
Bring Your Own Model
Set an OpenAI, Anthropic, Gemini, Groq or Ollama provider key in the Environment editor and redeploy when you want your own model.
Private Postgres With pgvector
Postgres runs privately alongside the server with no database port exposed, storing agents and their vectorized memory.
Your Agents, Your Server
Agents, memory blocks and configuration all stay on a server you control instead of a third-party agent-hosting account.

What You Can Do With Letta

Run agents with persistent memory
Create agents with memory blocks and have them remember across sessions, with state kept in your own Postgres database.
Build agents into your application
Call the REST API, or use the Python and TypeScript SDKs, to create agents and send them messages from your own code.
Choose your own model provider
Add an OpenAI, Anthropic, Gemini, Groq or Ollama setting in the environment to use your own model instead of the free hosted one.
Keep agent state on your own server
Agents, memory and configuration live in a database on your Cloud VPS, not in a hosted vendor's platform.

Letta vs Alternatives

Hosted agent platforms: A hosted platform holds your agents and memory on its servers. Letta is Apache-2.0 licensed, and here the server and its Postgres database run on your own Cloud VPS.
Engram: Engram is a persistent memory sync server for AI coding agents, with its own xCloud template. In a letta vs engram choice, Letta is a full agent server behind a REST API.
Basic Memory: Basic Memory is a self-hosted MCP server that keeps a Markdown knowledge base for AI assistants, with its own xCloud template. Letta runs stateful agents themselves.
Letta's hosted cloud: Upstream also offers Letta as a hosted cloud and a hosted Agent Development Environment. This page is the self-hosted server, which that environment can be pointed at.

Hear what people are saying about us

See why agencies, developers, startups, and growing businesses choose xCloud to power their projects.

xCloud works really well, I am surprised by its performance being this the release version, I have tried many paid platforms such as runcloud, cloudpages or serveravatar, as well as free platforms such as CyberPanel, CloudPanel or Hestia Control Panel and direct competitors such as SpinupWP and FlyWP. Of all those that I have tried, the platform that works best for WordPress is SpinupWP and I believe that xCloud can reach and surpass that development, its roadmap is promising. Congratulations to the xCloud team, I hope they become the leading platform in the segment, it has all the potential to achieve it!

Brian Geovanny

I've been with runcloud for the last 3 years. However, after trying xcloud for the last month, I'm switching over. They are on a roll with their setup.

Kevin Pineda

I'm moving my servers to xCloud, a cloud control panel by M Asif Rahman and the WPDeveloper team. Their roadmap looks interesting and no, there are no team mates nor API limits with xCloud! #xCloud #wordpress #hosting

How Cloud Nine Web Elevated Client Experience While Streamlining Hosting Operations using xCloud

Ed Ellingham

xCloud is like having an expert server team on call — without the big agency costs. It's given me back my time and given my clients peace of mind. Highly recommended for freelancers and small teams who want reliable performance and security.

Dumitru Butucel

xCloud isn't just a solution. It's like one of that friend who got your back when you screw things up pretty bad.

Waqar Ahmed

Trust me when I say, once people explore the potential of xCloud they gonna switch from other panels, just keep delivering the best tech, lots of love for the team 😍😍

Rahul Singh

So far my experience has been smooth like silk. I didn't imagine that configuring and managing a VPS would be so easy. As of today, I have deployed 8 sites. The support is good, and they treat users with respect, even if they ask stupid questions (myself included). For the future, I hope for greater flexibility in scheduled backups and more comprehensive and consistent documentation. I'm sure that within a few months, xCloud will become the leader in its segment. This community is amazing, and the Staff here is super helpful.

Massimo Villa

Came from cloudways then to runcloud then to xcloud. Looks like I'm staying here.

Gerson El

I've recently taken all of my Vultr-hosted sites and gotten rid of cPanel for them to substitute it with xCloud. I have to say, I'm really impressed with xCloud so far! The interface is definitely the standout feature for me.

Tony Lewis

I came from Cloudways and won't go back. Highly impressed with xCloud. Glad I gave them a chance.

Jared McDowell

I like xCloud better than RunCloud, but one thing I'll point out is that some years ago RunCloud was hungry for business, the support was outstanding, and the community was active and helped each other. Maybe it was sold, there was a change in management, or they stopped being hungry, but the quality of the RunCloud offering declined and it hasn't been moving forward quickly. My point is that currently the xCloud team has the edge and it is theirs to keep or lose

How Kevin Heinrichs Cut Hosting Costs by 84% While Running WooCommerce & Node.js Sites Efficiently

Kevin Heinrichs

I had 150 sites on cloudways and am in the process of moving them to xcloud. Much faster and better priced.

Dan Spinoza

Dear xCloud Team, I have been using xCloud for some time now and am genuinely impressed with its capabilities and the flexibility it offers by allowing users to bring their own VPS for management. It's a fantastic service, and my experience so far has been very positive. Successful migrated 5 sites on a single server. Xcloud migration tool worked great. There were few hiccups with security plugin like MalCare but disabling the plugin prior to migration worked just fine.

Rahil Maknojia

Came from runcloud. Tried xcloud and never came back.

xCloud gave me what no other hosting platform could: the flexibility of a VPS with the convenience of managed WordPress. As a solo founder running an entire business on one server, that combination is an important unfair advantage.

Frequently Asked Questions

Feel free to contact us with any questions or concerns you may have.

How much RAM does Letta need?

The manifest asks for 2 CPU cores, 1024 MB of RAM and 10 GB of disk as a floor. The 6 GB Cloud VPS sold on this page leaves comfortable headroom for the server and its Postgres database, and model calls run at your provider.

Is Letta free and open source?

Yes. Letta is Apache-2.0 licensed, per the LICENSE file at the 0.16.8 tag, so no licence fee applies. xCloud's only charge is the dedicated Cloud VPS. Your model provider's own charges are separate and depend on the provider you add.

Can you run Letta with Docker?

Yes, and this is Letta Docker hosting prepared for you: the template runs the Letta 0.16.8 server image beside the ankane pgvector Postgres image, both pinned by immutable digest, with HTTPS on your domain, so it is Letta cloud hosting on your own VPS.

What is the difference between Letta and MemGPT?

Letta was formerly MemGPT, per the README, so they are the same project under its newer name. The README also covers Letta Code, a command-line tool for local agents; this template deploys the server and REST API, not the CLI.

Does the Letta server have a web interface?

Not in the server image. Use the hosted Agent Development Environment at app.letta.com, a separate externally hosted product, pointed at your API URL, or use a Letta SDK client. The environment connects from your browser to your server.

How do I authenticate to the Letta API?

Send the generated API password as a bearer token on every request; it is shown in the protected installation credentials. Only the health check endpoint skips authentication. Letta also prints the password to container logs at startup, so limit log access.

Which models can I use with Letta?

Out of the box only Letta's free hosted model works. Add an OpenAI, Anthropic, Gemini, Groq or Ollama setting in the Environment editor and redeploy to use your own provider. Once an OpenAI key is set, agents using the free model stop working.

Can I change the Letta encryption key later?

No. The encryption key must not change after install, so treat it like any other stable application secret and keep a private copy. The database password is also only set on an empty volume and is rotated inside Postgres, not here.

What should I back up on a Letta server?

Both volumes: letta_db for the Postgres database with agents and memory, and letta_data for the Letta configuration and sandbox files, plus your stable environment values. Stop the stack for a consistent copy, keep it off the server, and test a restore.

Backups in xCloud

How do I upgrade Letta?

Nothing upgrades it for you: the install stays on pinned release 0.16.8 until you adopt a newer template version. Take backups of both volumes first, read the upstream release notes, then check that an existing agent and its memory are intact.

Can I cancel anytime?

Yes. There is no lock-in — cancel any time. Hosting is billed monthly and charged for what you actually use, so when you delete the server the unused balance is refunded to your account, less up to 10% in payment-processing fees.
