Cloud & Infrastructure / Deep Dive
SELF-HOSTED
Run your own CRM, ERP, file drive, password vault, and team chat on a private VPS — keep the data, drop the per-seat fees.
Own the stack, not just a subscription
Self-hosted business tools run on infrastructure you control — 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 applications such as a CRM, an ERP, a file drive, a password manager, and a team chat onto a single host, then access them through your own domain. The result is the same operational coverage as a stack of cloud subscriptions, with three differences that matter at scale: the data stays on infrastructure you administer, the cost stops scaling with headcount, and the integrations between tools are no longer locked behind paywalls. For a growing business, that combination is usually the difference between a tool stack that supports the team and one that taxes it.

What you actually deploy
A typical self-hosted business stack covers the same surface area as a SaaS bundle but as discrete containers behind a single reverse proxy. Each app gets its own subdomain and runs in isolation, with shared backups and shared user identity 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. The 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
Why teams move off bundled SaaS
The decision to self-host rarely starts with ideology. It usually starts with a renewal quote: a CRM that doubled its per-seat price, a file storage tier that triggered an unwanted upgrade, or an ERP add-on that locked a feature behind a higher plan. At that point, a self-hosted equivalent on a $20–$60/month VPS starts to look serious — not because the software is free, but because the cost stops scaling with headcount, the integrations stop being a paid SKU, and the data stops living somewhere a vendor can rate-limit. The other common trigger is compliance: clients in legal, healthcare, finance, or government work increasingly require their data to live on identifiable infrastructure, with named operators, in a known jurisdiction. A VPS in a region you choose, administered by a team you can name, satisfies that requirement in a way a multi-tenant SaaS rarely does.
What this looks like in practice
A typical small-business deployment lands on a single mid-tier VPS — 4–8 vCPU, 8–32 GB RAM, fast NVMe storage — running a Docker host with a reverse proxy in front. Five to ten apps share that 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 a different building, holds nightly encrypted backups. Restores are tested on a schedule, not assumed to work. Operating cost lands somewhere between $30 and $150/month for the host, plus the engineering time to keep it healthy — which is exactly the part most teams want a partner to handle. That is the gap this service fills.

FAQ
Frequently asked questions
Answers built for decision-makers who need clarity before committing.
Below ~5 users, the savings versus SaaS are marginal — the VPS plus engineering time often equals the subscription. The break-even tends to land between 8 and 15 users, depending on how many tools you bundle. Past that, self-hosting is reliably cheaper, and the cost stops scaling with every new hire.
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 are delivered to storage you control. MrZaKaRiA operates the host under a service agreement; ownership of the underlying infrastructure and data never transfers.
What happens if the VPS goes down?
Every deployment includes a documented recovery path: nightly snapshots, off-site backups in a different region, and a tested restore procedure. For business-critical workloads, a warm standby host can be added so a failed primary is replaced in minutes rather than hours.
Can self-hosted apps still talk to external services?
Yes. Self-hosted does not mean isolated. The apps continue to send and receive email, integrate with payment providers, sync with accounting platforms, and connect to AI APIs. The difference is that the system of record — the CRM, the ERP, the file store — lives on infrastructure you control.
Is this compliant with GDPR, HIPAA, or similar regulations?
A self-hosted stack is usually easier to make compliant, not harder, because data residency, access logs, encryption, and retention are entirely under your control. The deployment is configured to meet the specific regulation that applies to your industry — region selection, encryption at rest, audit logging, and data-processing documentation are all part of the build.
What if we already use SaaS and want to migrate?
Most modern SaaS tools have an export. The migration is usually a three-step pattern: export from the SaaS vendor, transform into the self-hosted app's import format, validate against a staging environment, then cut over with a short read-only window. We can run the migration end-to-end or coach an internal team through it.
