Here’s a result that cuts against the usual self-hosting pitch: at 100 users, self-hosted Taiga’s estimated TCO runs about $1,500/month, while Jira Standard for the same headcount is $775/month — Jira actually comes out cheaper, and even Jira Premium at $1,525/month is roughly a wash. The gap that usually favors open source gets eaten by engineering time; Taiga’s software is free, but running it at scale isn’t.

Hidden Costs of Jira

Beyond the advertised per-user pricing, Jira’s ecosystem frequently introduces additional expenditures that can inflate the total cost:

  • Atlassian Marketplace Apps: Many essential functionalities, such as advanced reporting, custom workflows, or integrations, are provided by third-party apps, often adding $3–20/user/month per app. These can quickly compound.
  • Confluence: For comprehensive documentation and knowledge base management, Confluence is frequently required but licensed separately, adding another per-user cost.
  • Jira Service Management (JSM): If your teams need IT service management or customer support capabilities, JSM is a separate product with its own pricing structure.
  • Storage Overages: While the Standard tier offers 250GB, larger teams or those with extensive attachments can quickly exceed limits, potentially forcing an upgrade or incurring additional fees.

Total Cost of Ownership (TCO) Analysis for Taiga (Self-Hosted Open Source)

Taiga offers a compelling open-source alternative to Jira, providing robust Kanban and Scrum boards, issue tracking, and backlogs. While it eliminates direct SaaS subscription fees, it introduces infrastructure and maintenance costs.


Cost Trade-offs at a Glance


Hosting & Server Resource Estimation

Estimates for cloud hosting (e.g., AWS EC2, Azure VMs, Google Cloud Compute Engine) for a typical Taiga deployment (web server, database, real-time backend).

  • Small Teams (Up to 20 users):
    • Requirements: 2-4 vCPU, 4-8 GB RAM, 50-100 GB SSD.
    • Estimated Monthly Hosting Cost: $30 - $60
  • Medium Teams (21-100 users):
    • Requirements: 4-8 vCPU, 8-16 GB RAM, 100-200 GB SSD.
    • Estimated Monthly Hosting Cost: $80 - $180
  • Large Teams (100+ users):
    • Requirements: 8-16+ vCPU, 16-32+ GB RAM, 200+ GB SSD (potentially distributed setup).
    • Estimated Monthly Hosting Cost: $200 - $500+

Maintenance & Engineering Support Estimation

The “free” aspect of open source often translates into internal engineering effort. These estimates assume an average DevOps/System Administrator hourly rate of $100/hour.

  • Small Teams (Up to 20 users):
    • Effort: 2-4 hours/month (setup, updates, backups, minor troubleshooting).
    • Estimated Monthly Engineering Cost: $200 - $400
  • Medium Teams (21-100 users):
    • Effort: 4-8 hours/month (more frequent updates, monitoring, performance tuning, scaling).
    • Estimated Monthly Engineering Cost: $400 - $800
  • Large Teams (100+ users):
    • Effort: 8-16+ hours/month (dedicated support, advanced scaling, security audits, potentially custom development).
    • Estimated Monthly Engineering Cost: $800 - $1600+

Comparative TCO Table (Monthly Estimates)

Team Size Jira (SaaS Fees - Standard Tier) Taiga (Infrastructure Cost) Taiga (Engineering Support) Taiga (Total Self-Host TCO)
5 users $38.75 $40 $300 $340
20 users $155 $100 $600 $700
100 users $775 $300 $1200 $1500

Note: Jira costs are based on annual pricing equivalent for optimal comparison.

Scenarios: Cost Comparison

Scenario 1: Small Team (5 users)

  • Jira Free: $0/month (Limitations: 10 users, 2GB storage, basic roadmaps)
  • Jira Standard: 5 users * $7.75/user = $38.75/month
  • Taiga (Self-Hosted): ~$340/month ($40 infrastructure + $300 engineering)

For a small team, Jira’s Free tier is undoubtedly the most cost-effective option if its limitations are acceptable. If more features or storage are needed, Jira Standard is significantly cheaper than self-hosting Taiga, primarily due to the engineering overhead.

Scenario 2: Medium Team (20 users)

  • Jira Standard: 20 users * $7.75/user = $155/month
  • Jira Premium: 20 users * $15.25/user = $305/month
  • Taiga (Self-Hosted): ~$700/month ($100 infrastructure + $600 engineering)

Jira Standard remains a very competitive option. Even Jira Premium, with its advanced features and 24/7 support, is less than half the cost of self-hosting Taiga for a team of this size.

Scenario 3: Large Team (100 users)

  • Jira Standard: 100 users * $7.75/user = $775/month
  • Jira Premium: 100 users * $15.25/user = $1525/month
  • Taiga (Self-Hosted): ~$1500/month ($300 infrastructure + $1200 engineering)

At this scale, the TCO for self-hosting Taiga becomes comparable to, or even exceeds, Jira’s Premium tier. While Taiga offers full control, the cumulative cost of infrastructure and dedicated engineering effort closes the financial gap with Jira’s SaaS offerings.

When Does Paying for Jira Actually Save Money?

Paying for Jira often provides a net saving when:

  1. Lack of Internal Expertise: Your organization lacks dedicated DevOps, SRE, or backend engineering talent to set up, secure, maintain, and troubleshoot a self-hosted application. The cost of hiring or allocating such talent often far outweighs SaaS fees.
  2. Focus on Core Business: If your engineering team’s primary focus should be on product development, not infrastructure management for internal tools. The opportunity cost of diverting engineering resources can be substantial.
  3. Need for Enterprise Features & Compliance: Jira’s Premium and Enterprise tiers offer features like advanced roadmaps, sandbox environments, capacity planning, SAML SSO, data residency, and enterprise-grade support, which are critical for larger, regulated organizations and not easily replicated with open-source tools without significant custom development.
  4. Extensive Integration Ecosystem: Jira’s vast Atlassian Marketplace and robust API support a wide range of integrations with other business tools (CI/CD, CRM, reporting). While Taiga offers integrations, Jira’s ecosystem is generally more mature and plug-and-play.
  5. Scalability & Uptime Guarantees: SaaS providers like Atlassian handle scalability and provide uptime SLAs, offloading this critical responsibility from your internal teams.

Final Purchasing Recommendation

  • For very small teams (up to 10 users) with basic needs: Jira Free is the most cost-effective solution, offering a robust feature set without any financial commitment.
  • For small to medium-sized agile teams (10-50 users) focused on product delivery: Jira Standard offers a clear value proposition. Its per-user cost is significantly lower than the total cost of self-hosting Taiga when accounting for engineering time, and it provides a reliable, scalable platform.
  • For medium to large organizations (50+ users) requiring advanced capabilities, high availability, and dedicated support: Jira Premium or Enterprise are strong contenders. While the per-user cost is higher, it includes features and support that would be extremely expensive and complex to replicate with a self-hosted solution.
  • For organizations with strong internal DevOps capabilities, strict data sovereignty requirements, or a philosophical preference for open source and complete control: Self-hosted Taiga can be a viable option. Budget for the full TCO honestly, though — the engineering hours in the tables above are what actually determine whether this saves money, not the $0 software license.

This is one of the few comparisons on this site where the SaaS option doesn’t lose on cost at scale. If your only reason for considering Taiga is “self-hosting is cheaper,” run the numbers for your actual team size first — at 100 users, that assumption stops being true.

よくある質問

If my team outgrows Jira's 10-user free limit, what are the hidden cost differences compared to hosting Taiga?

Jira's Standard tier starts at $8.15 per user/month, but total costs often scale up quickly because Atlassian Marketplace apps add an extra $3 to $20 per user/month, and Confluence documentation is licensed separately. Conversely, Taiga is open-source under the Mozilla Public License 2.0, allowing you to completely bypass per-user licensing fees by self-hosting its Docker, Python, and Nodejs stack. This makes Taiga a highly budget-friendly alternative if you want to avoid Jira's marketplace upcharges and dedicated administrative overhead.

Does Taiga's 8/10 agile overlap score mean I can avoid paying for Jira's expensive Premium tier?

Jira restricts advanced roadmaps and capacity planning to its Premium tier, which costs $16 per user/month, while its $8.15 Standard tier only includes basic roadmaps. With an 8/10 overlap score, Taiga delivers its core Scrum and Kanban boards, backlogs, and issue tracking out-of-the-box under the Mozilla Public License 2.0. Self-hosting Taiga allows teams to manage robust agile projects without upgrading to Jira's costly Premium tier or paying for extra storage overages.
