What Is a Self-Hosted Chat Server?
A self-hosted chat server is a messaging platform that you deploy and operate on infrastructure you control — whether that is a cloud account (AWS, Azure, GCP), a third-party data centre, or on-premises hardware. Unlike SaaS chat services where your messages and user data live on the provider’s servers, a self-hosted solution gives you complete ownership of the data, the configuration, and the security perimeter.
Organizations choose self-hosted chat for several reasons: regulatory compliance (HIPAA, GDPR, SOC 2), data sovereignty requirements, the need to integrate messaging deeply into existing systems, or simply the assurance that comes with knowing exactly where every message is stored and who has access. For industries like healthcare, finance, and insurance — where a data breach or compliance violation can mean millions in penalties — a self-hosted chat server is not just a preference but a requirement.
Ethora’s self-hosted chat server provides a full-stack solution: XMPP chat server, Node.js API layer, admin dashboard, push notifications, file storage, and optional AI services — all deployed as a single managed package on the infrastructure of your choice. Unlike open-source alternatives that require weeks of configuration and ongoing maintenance by your team, Ethora’s managed deployment gets your self-hosted chat server running in hours with an enterprise SLA from day one.

Self-Hosted Team Chat vs SaaS: When to Choose Self-Hosted
SaaS chat is convenient for small teams, but businesses handling sensitive data or serving regulated industries outgrow it quickly. Here is when a dedicated managed chat server wins:
Healthcare (HIPAA), finance (GLBA, PCI DSS), insurance (PIPEDA), and government agencies require data to remain within controlled environments. A self-hosted server lets your compliance team audit and certify the messaging infrastructure alongside the rest of your systems.
When your data must stay in a specific country or data centre, self-hosted deployment gives you full control over geography. Deploy in the EU for GDPR, in Canada for PIPEDA, or in the Middle East for local regulations.
SaaS platforms offer APIs, but a self-hosted server lets you connect at every layer: database, message bus, authentication, and backend services. Build workflows that SaaS chat platforms cannot support.
SaaS chat pricing typically scales with monthly active users or messages sent. For applications with large user bases, a self-hosted server provides a fixed infrastructure cost regardless of user count.
Self-hosted deployments allow full UI customization and white-labelling, so your chat experience matches your brand and product — not the chat vendor’s.
When encryption must be verifiable and auditable, self-hosting keeps TLS termination, the keys that encrypt data at rest, message stores, and transport channels inside your security perimeter. No third party holds your keys or your messages, your own team can audit the configuration, and from release 2610 you can switch on end-to-end encrypted rooms per app so the server stores only ciphertext.
For teams that do not need compliance controls or deep integrations, Ethora also offers a cloud-hosted plan with the same features and zero infrastructure management. Many businesses start on cloud and migrate to self-hosted later as requirements evolve.
Enterprise and internal messaging
A Self-Hosted Enterprise Messaging Platform You Fully Control
For enterprises and internal teams, messaging is not just a feature. It is infrastructure that carries internal discussions, customer information, and sensitive business data every day. Ethora gives you a secure, self-hosted enterprise messaging platform your organisation controls end to end: you decide how it integrates with your systems, who has access, and how the data is managed. No per-seat pricing, no third-party hosting, and no vendor lock-in.
Internal communication platform, self-hosted
Give employees one place for internal communication without moving business conversations to another company’s cloud. Role-based access and SSO keep access to the right people; audit trails and admin controls give IT and security teams visibility into how the platform is used.
Enterprise messaging platform, on your terms
Enterprise messaging should fit the IT environment you already run. Ethora works with your identity provider, CRM, backend applications, and other systems, and you choose who operates it: Ethora TechOps under an enterprise SLA, or your own infrastructure team.
Secure business messaging
Keep confidential conversations inside your security perimeter. Encryption in transit and at rest, optional end-to-end encrypted rooms switched on per app, role-based access, and audit logs give security and compliance teams control over where messages are stored and who can reach them.
Corporate messaging app, fully branded
Build a corporate messaging app that fits your organisation instead of sending employees to a generic third-party product. Web, iOS, and Android clients run from the same self-hosted backend, with your branding and UI, alongside your existing internal applications.
Open-source messaging platform, no lock-in
An open-source foundation with source code access for organisations that need flexibility on the server side. Inspect and extend the system, integrate it with your infrastructure, and move between hosting providers without rebuilding your messaging around one cloud.
Predictable cost at scale
Instead of a SaaS fee for every employee account, your main cost is the server environment running the platform, on a flat monthly licence. For larger organisations that makes cost easier to plan as headcount grows.
Own your enterprise messaging
Secure internal communication, an enterprise SLA, and a corporate messaging app your employees want to use
Whether you need a secure internal communication platform for regulated teams, an enterprise messaging platform with a real SLA, or a branded corporate messaging app, Ethora runs it on infrastructure you control: the same self-hosted chat server, extended for internal and enterprise communication, with compliance readiness and an open-source foundation your security team can sign off.

Hosting Infrastructure (IaaS Provider) Options
Deploy your Ethora chat server the way your project and compliance needs require — from a managed AWS sub-account to your own cloud or on-premise data centre.
Ethora’s AWS sub-account
Default
The default option offered by Ethora is deploying your self-hosted chat server in a sub-account at Ethora’s own Amazon Web Services. This ensures the ease of use for the Customer, while leveraging all the advantages of the dedicated server and enterprise-level SLA. The Customer can choose between any of the Availability Zones to ensure their messaging infrastructure is close to the end users geography.
Your infrastructure AWS · Azure · GCP · on-premises
Enterprise SLA Managed by Ethora
Your own AWS / other IaaS account
Your cloud
In case you, the Customer, prefer or required by your project or your vertical’s compliance or security constraints, to host the system in your own infrastructure, this option is fully supported. The specific configuration and access for Ethora SLA team here will depend on your Ethora infrastructure configuration and the options selected for your license and SLA contract with Ethora. A typical setup would be where Customer has a Dev and Prod servers fully managed by Ethora, another popular configuration is where Customer’s Prod server is isolated where Ethora’s TechOps team only has access to Customer’s Dev server, and Customer’s own team is managing the Prod server. This makes SLA servicing and tech support more difficult but ensures any of the end users data is not physically accessible by Ethora’s technical team which may be a requirement in some verticals or projects.
Procurement
Ethora is listed on AWS Marketplace, with Azure Marketplace and DigitalOcean to follow, so your cloud team can deploy from the console they already use and apply committed cloud spend. Enterprise terms are available as a marketplace private offer or as a direct contract.

On premise (your own data centre)
On premise
It is important to note that Ethora platform is infrastructure agnostic. Our standard operational system is Ubuntu Linux and we support both amd64 and arm64 configurations, with amd64 being the default choice. This means our infrastructure does not rely on any specific services or integrations of the popular Infrastructure-as-a-Service providers such as Amazon Web Services, Microsoft Azure, Google Cloud Platform. This, in turn, means you are not vendor locked into one single IaaS provider, you have the freedom to choose between one of the providers and the freedom to migrate your Ethora server(s) between infrastructure providers in future. Consequently, this also means that Ethora can be hosted at other 3rd party data centres or on premise. This is especially relevant for some of our Customers where applicable (country-specific or vertical-specific) laws or compliance constraints require all data to be constrained to specific geography or specific data centre. Choosing Ethora server fully addresses these constraints.

Geography of Your Chat Server
With messaging, human and AI communications, it is important that the messaging feels instant and the latency is minimal.
Most of Ethora customers here benefit from the flexibility of Ethora deployments by choosing to install their Ethora server(s) in the hosting infrastructure (AWS Availability Zone, an alternative with another IaaS, a local hosting provider, or Customer’s own on premise data centre).
Advanced options are available here, such as multi-zone deployments, however in practice for most Customers the optimal solution is to deploy in one geography that is closest to their userbase.
