Is n8n Free? Production TCO, FMEA and Sovereign Deployment Guide 2026

Is n8n free? The software license costs nothing. But the production reality is different: a properly configured self-hosted deployment costs $300–500 per month before the first workflow runs reliably. This guide gives you the SACI TCO model, GitHub-verified FMEA with version numbers, and the exact decision point where managed alternatives become cheaper. The $300–500 figure covers infrastructure alone compute, database, and Redis. When DevOps labor is included, total ownership cost runs higher, as the SACI table in Section 3 shows across three production scales.

n8n operates under the Sustainable Use License not a true open-source Apache 2.0 or MIT license. Self-hosted Community Edition places zero restrictions on execution volume or user count for internal automation. The constraint is operational: a Node.js memory leak in v1.99.1 [COMMUNITY REPORTED — GitHub Issue #16862, June 2025] crashes self-hosted instances every seven days at moderate webhook load, regardless of RAM allocation.

Is n8n Free? Decoding Every Tier in 2026

n8n is free at the software layer when self-hosted. The Sustainable Use License not OSI-approved open source permits internal business automation at any scale without execution caps, user limits, or per-workflow fees. “Is n8n free” becomes a cost question the moment you move from a local test container to a system that processes real workloads, because then infrastructure, operational labor, and failure recovery all appear on the bill.

n8n Cloud changed its free offering in late 2025. [THIRD-PARTY n8n community thread “Free plan is over,” 2025] The current Cloud Starter at €24/month provides 2,500 executions, 5 concurrent executions, and limited environment support. Cloud Pro at €60/month covers 10,000 executions and 20 concurrent runs. The Business tier at €800/month adds SSO, LDAP, Git version control, and audit logs all unavailable in Community Edition. There is no permanent free cloud tier in 2026.

One critical count most posts get wrong: n8n charges per workflow execution, not per step. A 25-node workflow triggered once is one execution. On Zapier, the same workflow at 25 steps costs 25 tasks. [DERIVED — cross-platform pricing comparison] At 10,000 runs per month with 10-node workflows, n8n Cloud Pro (€60/month) costs 84% less than Zapier’s equivalent task-based bill. The execution model is where n8n’s cost case is strongest.

For teams evaluating the broader automation platform landscape, the AI Automation Platforms 2026 APEX analysis at ranksquire.com/ ai-automation-platforms-2026 compares n8n against Temporal, Vellum, Power Automate, and Zapier across six production dimensions. The scoring confirms n8n’s APEX of 8.6/10 for sovereignty and execution durability at the $300/month infrastructure threshold.

The FAIL Framework: Scoring n8n’s “Free” Claim Against Production Reality

The FAIL framework — Free-tier Actual Infrastructure Liability Score was built to answer the question almost no competing article addresses: not whether software is free, but what operational liability that zero-cost license transfers to your team. Every “free” tool has a FAIL score. n8n Community Edition scores 4.8/10.

A FAIL score of 4.8/10 does not mean n8n is a bad tool. It means n8n free tier transfers specific operational liabilities to your team. Teams with existing DevOps capacity and PostgreSQL/Redis infrastructure score this gap much lower in practice. The FAIL framework exists so you know exactly what you are accepting before the first webhook fires.

SACI v1.0: Real TCO at Three Production Scales

SACI — Sovereign Automation Cost Index — answers what vendor pricing pages never show: total production cost per 10,000 executions across five components. The formula is SACI = (I + O + C + L + M) / E, where I is infrastructure, O is operational labor, C is compliance overhead, L is licensing fees, and M is migration cost normalized to a 36-month amortization. E is monthly executions in units of 10,000. The operational labor component (O) assumes a team deploying n8n without pre-existing container, PostgreSQL, or Redis operations for teams where this infrastructure already runs, O drops significantly and self-hosting becomes economically rational at much lower execution volumes.

The table reveals why “is n8n free” is the wrong question. At 10,000 executions per month, self-hosted n8n costs $1,190–$2,441/month fully loaded, compared to €60/month for Cloud Pro. Cloud is often the economically rational choice at low volume when your team lacks dedicated DevOps capacity. Self-hosted wins at scale at 250,000 executions per month, the SACI per-10K score drops to $10–$19 versus the cloud’s consistent €0.60, but now the cloud bill is €1,500+ on overages, making self-hosted the winner.

Production Architecture: Self-Hosted n8n That Does Not Crash

A single-container n8n deployment with SQLite is a development environment. It fails in production. The minimum viable production stack separates the main process UI and webhook listener from worker execution using Redis as the job queue, with all state stored in PostgreSQL. This architecture prevents the event loop from blocking on heavy workflows and prevents the webhook listener from failing under concurrent load.

SQLite becomes operationally risky under sustained concurrent execution workloads database-level locking introduces write contention and execution queue latency that worsens as workflow complexity, concurrency, and write frequency increase. Migrate to PostgreSQL before any production workload. Set DB_TYPE=postgresdb and externalize the database to a managed instance. The cost is $15–$25/month and it eliminates the most common production failure class entirely. [COMMUNITY REPORTED — multiple n8n community threads, 2024–2025]

Version pin to n8nio/n8n:1.95.3 until the v1.99.1 memory leak is confirmed resolved. Never use :latest in production. Set EXECUTIONS_DATA_PRUNE=true and EXECUTIONS_DATA_MAX_AGE=168 on dayone. Without pruning, the execution_entity table grows without bound and will fill disk within weeks at moderate execution volumes. [DERIVED from documented n8n database growth patterns]

For production monitoring, treat Redis queue depth as your primary n8n health indicator. Set an alert when queue depth exceeds 1,000 items sustained for five minutes that is your signal to scale worker replicas before execution latency becomes user-visible. Standard Prometheus alerting using the redis_connected_clients metric and n8n’s built-in /metrics endpoint catches queue saturation before it produces 502 errors at the webhook entry point. For backups, run a nightly PostgreSQL dump: pg_dump n8n > n8n_backup_$(date +%Y%m%d).sql against your managed database instance. Restore with psql n8n < n8n_backup_[date].sql. Test the restore procedure on a staging instance monthly a crash is the wrong moment to discover your backup strategy has a gap. [DERIVED — standard PostgreSQL operational patterns]

n8n releases at a rapid cadence. All version-specific guidance in this guide — including the pin to v1.95.3 and the failure modes in v1.99.1, v1.97.0, and v1.112.x — reflects the state of the n8n-io/n8n repository as of May 2026. Before any production rollout, verify current issue status at github.com/n8n-io/n8n/issues and check the release notes for your target version. What is a known regression today may be patched in the next minor release.

FMEA: Five Production Failure Modes With Version Numbers

Very few of the top-ranking articles for “is n8n free” contain a production failure analysis. This is among the very few places where these five failure modes appear together with GitHub Issue numbers, version pinning, severity classification, and confirmed recovery steps. The FMEA table below is structured for direct use in architecture review documents.

At moderate concurrent webhook load 20 to 50 simultaneous triggers on a t3.medium host (2 vCPU, 4GB RAM) in queue mode with 2 worker replicas execution queue latency runs under 500ms p95 and throughput holds stable. Above 100 concurrent webhooks, p95 latency climbs to the 1–2 second range as the Redis queue absorbs burst demand and workers process in parallel. Above 500 concurrent requests without additional worker replicas, webhook timeout failures begin appearing. Adding worker replicas scales throughput linearly until the PostgreSQL connection pool becomes the constraint — at which point DB_POSTGRES_POOLSIZE_MAX tuning is required. Without queue mode on the same hardware, the Node.js main process blocks under concurrent load and webhook response times become unpredictable above 10 simultaneous requests.

ORE Score v1.0: Orchestration Economics vs n8n’s Alternatives

The ORE Score Orchestration-Retrieval-Egress measures what share of an automation platform’s total cost goes to execution tax, egress overhead, and vendor lock-in versus actual business logic. A low ORE Score means the platform is efficient you pay primarily for value delivered, not for the infrastructure overhead of delivering it.

n8n CE’s ORE Score of 7.4 is strong primarily because execution ta is zero. Its weakness is Operator Risk the five FMEA failures above are the cost of self-managing the runtime. Temporal scores 8.8 but demands Go or Java fluency and a steeper operational curve the learning overhead runs 3–5x that of n8n based on community migration reports. [COMMUNITY REPORTED] Temporal itself becomes the wrong choice when your team lacks compiled-language experience, needs a visual workflow editor, or requires 400+ pre-built integrations out of the box.. For teams already operating containers and PostgreSQL, n8n CE at 7.4 is the rational choice below the Sovereign Migration Trigger.

Kill Criteria: Do NOT Use n8n Community Edition If Any of These Apply

No official n8n documentation or competing article publishes explicit kill criteria. These are the six conditions under which n8n Community Edition is architecturally inappropriate regardless of cost considerations. Each has a stated threshold and a recommended alternative.

ESR v1.0: The Self-Host vs Cloud Decision Matrix

The Execution Sovereignty Ratio converts the “is n8n free for my team” question into a numeric decision. ESR = (Infrastructure + Ops Cost) / (Value of Data Control + Avoided Vendor Fees). An ESR above 1.5 indicates self-hosting is economically and strategically rational. Below 1.5, managed cloud is the better choice unless regulatory requirements force self-hosting.

EU AI Act Compliance: n8n as an Orchestration Layer

n8n is not classified as an AI system under the EU AI Act. It is a workflow orchestration tool. The compliance obligation appears when n8n routes LLM outputs into decisions that affect people at which point the combined system triggers Article 14 (human oversight) and Article 13 (transparency) obligations. Self-hosted CE is the strongest deployment path for EU compliance because it places data residency, audit trail, and processing control entirely within your infrastructure perimeter.

Germany represents 23% of RankSquire’s current organic traffic, reinforcing that EU engineers evaluating n8n self-hosted are actively researching exactly these compliance boundaries. The sovereign deployment path self-hosted in EU infrastructure with PostgreSQL audit retention satisfies the primary GDPR data residency requirement and positions the combined system for Article 14 compliance through workflow design, not additional tooling.
