Cloud & Infrastructure / Deep Dive
Self-hosted business tools on your own VPS
Self-hosted business tools run on a private VPS you control: your CRM, ERP, file drive, password vault and team chat, all on your own domain. You keep the data and drop the per-seat fees. We deploy, secure, back up and update the stack for a flat monthly fee.
SCROLL
Own the stack, not just a subscription
Self-hosted business tools run on infrastructure you control. That is usually a VPS, a private cloud instance or a small on-premise server. Instead of paying per seat to a SaaS vendor, you deploy open-source apps onto one host and reach them through your own domain.
The coverage matches a stack of cloud subscriptions. Three things change. The data stays on infrastructure you administer. The cost stops growing with headcount. The integrations between tools are no longer locked behind paywalls.
This guide is part of our managed cloud hosting service. It explains what you deploy, what we handle and when self-hosting makes sense.

What you actually deploy
A typical stack covers the same ground as a SaaS bundle, but as separate containers behind one reverse proxy. Each app gets its own subdomain and runs in isolation. Backups and user identity are shared, through a self-hosted SSO or a directory.
- CRM for contacts, deals, pipelines and email outreach
- ERP for invoicing, inventory and supplier management
- File drive with desktop and mobile sync clients
- Password vault with team-shared collections
- Team chat, video calls and a shared knowledge base
What MrZaKaRiA handles for you
Most teams do not want to learn Docker, reverse proxies or backup rotation just to escape a SaaS bill. Deployment, hardening, monitoring and updates run as a managed service. You keep the ownership and the data. We keep the host healthy.
- VPS provisioning, hardening and firewall configuration
- Containerised app deployment behind a TLS reverse proxy
- Automated nightly backups with off-site replication
- Update windows and rollback paths for every app
- Optional SSO, so one login covers the whole stack
One host. Many apps. One bill.
Why teams move off bundled SaaS
The decision to self-host rarely starts with ideology. It starts with a renewal quote. A CRM doubled its per-seat price. A storage tier forced an upgrade. An ERP add-on locked a feature behind a higher plan.
At that point a self-hosted equivalent on a VPS looks serious. The software is not free, because someone has to run it. But the cost stops scaling with headcount, integrations stop being a paid add-on and the data stops living where a vendor can rate-limit it.
The other common trigger is compliance. Clients in legal, healthcare, finance and government work increasingly want their data on identifiable infrastructure, with named operators in a known jurisdiction. A VPS in a region you choose, run by a team you can name, meets that requirement. A multi-tenant SaaS rarely does.

Off-site backups, tested restores
What a typical deployment looks like
A small-business deployment usually lands on one mid-size VPS with fast NVMe storage, typically 4 to 8 vCPUs and 8 to 32 GB of RAM. It runs Docker with a reverse proxy in front. Five to ten apps share the host: CRM, ERP, file drive, password vault, knowledge base, team chat, helpdesk and analytics.
Each app has its own subdomain and TLS certificate. A second, smaller VPS, or a NAS in another building, holds nightly encrypted backups. Restores are tested on a schedule, not assumed to work. Our disaster recovery guide explains how.
The monthly bill is the VPS plus our management fee. That management is the part most teams want a partner for, and it is what this service covers.

FAQ
Self-hosting questions, answered
What teams ask before they move off SaaS.
Below about five users the saving is small, because the VPS plus management can match the subscriptions. The gap widens as the team grows. The VPS bill stays flat while per-seat fees rise with every hire. We compare your real renewal quotes with the self-hosted cost before you commit.

Who owns the data and the host?
You do. The VPS is registered in your account or your company name, the domain is yours and the database backups go to storage you control. MrZaKaRiA operates the host under a service agreement. Ownership of the infrastructure and the data never transfers.
3
What happens if the VPS goes down?
Every deployment has a documented recovery path: nightly snapshots, off-site backups in a different region and a tested restore procedure. For business-critical workloads we can add a warm standby host, so a failed primary is replaced in minutes rather than hours.
4
Can self-hosted apps still talk to external services?
Yes. Self-hosted does not mean isolated. The apps still send and receive email, work with payment providers, sync with accounting platforms and call AI APIs. The difference is that the system of record, whether CRM, ERP or file store, lives on infrastructure you control.
5
Is a self-hosted stack compliant with GDPR or HIPAA?
It is often easier to bring into line, because data location, access logs, encryption and retention are under your control. We configure region, encryption at rest, audit logging and data-processing documentation for the rule that applies to you. Compliance also depends on your wider process, so we scope it with you.
6
What if we already use SaaS and want to migrate?
Most SaaS tools offer an export. The usual pattern has four steps: export from the vendor, convert to the self-hosted app's import format, validate on a staging environment, then cut over with a short read-only window. We can run the migration end to end or coach your team through it.
