n8n Queue Mode: Redis Workers for Parallel Executions
Standard Mode runs everything in one process. Queue Mode adds Redis and dedicated workers so heavy, concurrent workflows keep running. Learn how it works and when to upgrade.
Standard Mode vs Queue Mode — Feature Comparison
| Feature | Standard Mode | Queue Mode |
|---|---|---|
| Architecture | One n8n process handles UI, triggers and executions | Main process plus Redis queue plus worker processes |
| Parallel Executions | Share one process and its resources | Spread across 10 or 20 workers on SNBD HOST |
| Database | SQLite (1G, 2G) or PostgreSQL (3G and up) | PostgreSQL required |
| Webhook Bursts | Can slow the editor and other runs | Queued and processed by workers |
| Failure Isolation | A heavy run can affect the whole instance | A worker problem does not take down the main process |
| SNBD HOST Plans | n8n 1G to 4G (৳200 to ৳800) | n8n 6G and 8G (৳1,200 and ৳1,600) |
| Best For | Personal use, typical business automations | High-volume, concurrent or long-running workloads |
Pricing Math: n8n Cloud vs SNBD HOST
n8n Cloud meters executions: its Starter plan is about €20/mo for 2,500 executions. A managed SNBD HOST n8n plan is a flat monthly price for a private server with no per-execution cap, so your volume is limited by the CPU and RAM you choose, not by a counter.
| n8n Cloud Starter | n8n Cloud Pro | SNBD HOST n8n 3G | SNBD HOST n8n 6G | |
|---|---|---|---|---|
| Monthly price | €20 (annual billing) | €50 (annual billing) | ৳600 (about $4.88) | ৳1,200 (about $9.76) |
| Executions included | 2,500 / month | 10,000 / month | No per-execution cap | No per-execution cap |
| 12-month cost | €240 (about $264) | €600 (about $660) | ৳7,200 (about $59) | ৳14,400 (about $117) |
| At 25,000 executions / month | Over the plan limit | Over the plan limit | Flat ৳600 if workflows fit 3 GB RAM | Flat ৳1,200, 10 parallel workers |
| Database | Managed by n8n | Managed by n8n | PostgreSQL | PostgreSQL |
| Execution mode | Managed by n8n | Managed by n8n | Standard Mode | Queue Mode, 10 workers |
| Data location | n8n cloud | n8n cloud | Your private instance | Your private instance |

How n8n Queue Mode Works
In Queue Mode the main n8n instance receives triggers, webhooks and UI requests and writes each execution as a job to Redis. Worker processes pick jobs off the queue, run the workflow and write results to the shared PostgreSQL database. Adding workers adds parallel capacity without changing your workflows.
This is the architecture n8n recommends for scaling, and it is why a managed plan with 10 or 20 workers handles bursts that would stall a single process.
When to Upgrade to Queue Mode
Move up when you see executions waiting on each other, a sluggish editor while workflows run, webhook timeouts during traffic spikes, or memory pressure from large data-processing runs. Typical triggers are order processing for an online store, lead-capture webhooks, AI agent workflows with long LLM calls, and scheduled ETL jobs that overlap.
If none of that applies, stay on Standard Mode. A 3G or 4G plan with PostgreSQL is cheaper and enough for most teams. You can compare every plan on our managed n8n hosting page.
Queue Mode Without the DevOps
Self-hosting Queue Mode means running Redis, PostgreSQL, a main process and several workers on a server such as a BDIX VPS, then keeping all of them patched and backed up. SNBD HOST ships it ready: n8n 6G includes 10 workers and n8n 8G includes 20, both with PostgreSQL, daily backups and 24/7 support, and we migrate your existing instance for free.
Our Verdict
Stay on Standard Mode while your executions run one at a time. Choose n8n 6G or 8G with Queue Mode when concurrency, webhook bursts or long-running AI workflows start to queue up.
