Self-Hosting vs. SaaS: The Real Cost Comparison in 2025

The SaaS paradox

SaaS products sold themselves on simplicity: no servers to manage, no upgrades to run, no ops team required. Pay a monthly fee, use the software. For many teams, that deal made sense — especially in the early 2010s, when cloud infrastructure was expensive and devops talent was scarce.

In 2025, the equation has shifted. Cloud VMs cost €4–8/month for entry-level workloads. Open-source alternatives to almost every major SaaS tool now exist, are actively maintained, and can be deployed by a non-technical team in under 60 seconds. Meanwhile, SaaS pricing has steadily increased — often dramatically.

This article runs the real numbers for three common business tools: e-signatures, workflow automation, and document collaboration. We compare what you'd pay for the SaaS leader vs. self-hosting the open-source alternative on Syvera ClickCloud.

Case 1: E-Signatures — DocuSign vs. DocuSeal

DocuSign pricing (2025)

DocuSign's most popular "Business Pro" plan costs €40/user/month (billed annually). For a 10-person team that needs to send contracts, that's €400/month or €4,800/year — before you factor in the per-envelope overage charges that kick in above your monthly limit.

The "Standard" plan at €25/user/month limits you to 100 envelopes per month across the team. Hit 101, pay extra.

DocuSeal on Syvera ClickCloud

DocuSeal is MIT-licensed open-source software. Self-hosted on a Syvera CAX11 instance (2 vCPU ARM64, 4 GB RAM, 40 GB NVMe):

• Server cost: €8.99/month
• Number of users: unlimited
• Number of documents: unlimited
• Overage charges: €0

Annual cost: €107.88

The comparison

Annual saving: €4,692 — enough to hire a junior developer for two months.

The data sovereignty point is not trivial. DocuSign processes your contracts — which contain salary figures, client names, deal terms — on US infrastructure. For many European companies, this creates a compliance liability. With DocuSeal on Syvera, your documents never leave your EU server.

Case 2: Workflow Automation — n8n Cloud vs. n8n Self-Hosted

n8n Cloud pricing (2025)

n8n Cloud's "Starter" plan costs €20/month for 2,500 workflow executions. The "Pro" plan at €50/month gives you 10,000 executions. Beyond that, you're on the Enterprise tier — quoted individually.

For a marketing team running automated lead enrichment, customer onboarding sequences, and Slack notifications, 10,000 executions/month sounds like a lot — until you realise that a single multi-step workflow often counts as 4–8 executions. Real teams hit Pro limits quickly.

n8n Self-Hosted on Syvera

n8n is fair-code licensed and fully self-hostable. On a Syvera CX22 instance (2 vCPU x86, 4 GB RAM, 40 GB SSD):

• Server cost: €5.83/month
• Workflow executions: unlimited
• Number of workflows: unlimited
• Number of users: unlimited

Annual cost: €69.96

The comparison

Annual saving: €530 — for the first team member. Each additional user the SaaS charges for is another multiplier on that number.

For automation-heavy teams running hundreds of workflows, the self-hosted TCO advantage becomes decisive. One Syvera customer — a €50M B2B SaaS company — migrated 340 n8n workflows from n8n Cloud and cut their automation infrastructure costs from €2,400/year to €84/year.

Case 3: Document Collaboration — Notion vs. Nextcloud

Notion pricing (2025)

Notion's "Plus" plan costs €8/user/month. For a 20-person company, that's €160/month or €1,920/year. The Business plan at €15/user/month is often required once teams need advanced permissions and audit logs.

Nextcloud on Syvera

Nextcloud is GPL-licensed open-source software combining file storage, document editing (via Collabora Online), project management, and video calls. On a Syvera CAX21 instance (4 vCPU ARM64, 8 GB RAM, 80 GB NVMe):

• Server cost: €15.99/month
• Users: unlimited
• Storage: expandable via Syvera Object Storage at €0.019/GB

Annual cost: €191.88 (plus storage — comparable to what Notion charges for 5 users)

When SaaS still wins

This article is not an argument that self-hosting is always the right choice. There are real scenarios where SaaS is the better option:

Choose SaaS when:

• Your team has zero technical capacity and no appetite to learn
• The tool is mission-critical and downtime of any kind is unacceptable (requires active SRE team)
• You need enterprise support contracts with guaranteed SLAs
• The open-source alternative lags significantly in features you actually use
• The team size is 1–3 people and the SaaS free tier covers your needs

Choose self-hosting when:

• Your per-seat SaaS bill has grown to >€100/month for a single tool
• You handle sensitive data (contracts, HR records, financial documents) and need full data sovereignty
• You want unlimited users without per-seat pricing
• Your team includes at least one person comfortable with basic Linux administration — or you're using Syvera ClickCloud, in which case you don't need that person at all
• You want to customise or extend the software beyond what the SaaS vendor allows

The hidden cost of SaaS lock-in

The numbers above only capture direct costs. There's a subtler cost to SaaS that rarely appears in budget spreadsheets: lock-in.

When your company data lives in a SaaS vendor's proprietary format, switching costs are enormous. Migrating from DocuSign to a competitor means exporting thousands of documents, re-inviting signers, and rebuilding integrations. The vendor knows this — which is why SaaS pricing tends to increase 10–20% per year once a tool is embedded in your workflows.

Open-source software on your own infrastructure belongs to you. Your data is in standard formats. Migrating to a different version, a different server, or a different tool is always possible — without the vendor's permission.

The operational overhead objection

The most common counterargument to self-hosting is operational overhead: "Who maintains the server? Who handles updates? Who fixes it at 2am?"

This is a legitimate concern — for teams running their own bare-metal infrastructure with manually configured services. It is not a legitimate concern for Syvera ClickCloud deployments:

• OS security updates: applied automatically
• TLS certificate renewal: automatic (Certbot + systemd timer)
• Daily backups: automatic, one-click restore
• Health monitoring: 24/7, automatic restart on failure
• Scaling: one-click in the dashboard

The "who maintains it?" question answers itself: Syvera does, for €4–16/month.

The bottom line

For most small and medium-sized businesses, the self-hosting economics in 2025 are compelling — especially for tools that handle sensitive data or have high per-seat costs. The emergence of platforms like Syvera ClickCloud eliminates the only remaining objection: operational complexity.

You don't need a sysadmin. You need 60 seconds.
