n8n is the fast path to an internal automation and a slow path to a production agentic system. n8n connects apps and APIs on a visual canvas, with AI Agent nodes and, in preview, standalone n8n Agents. A production agentic system needs durable execution, agentic scale, streaming, and governance across every AI system — with n8n you provision and operate those yourself. Akka delivers them as one operated runtime, and stands behind it.
n8n is a visual workflow-automation tool that connects 2,000+ apps and APIs on a node-based canvas, with an AI Agent node built on the LangChain JavaScript framework. n8n fits integrations and internal automations, and self-hosting gives a team full control of its data.
To scale, n8n runs in queue mode: a Redis broker distributes executions to worker processes, PostgreSQL is required, and multiple main instances provide availability. Enterprise Cloud carries a 99.5% uptime commitment. Durable execution, agentic scale, and streaming fall outside that scope, and you provision and operate them. n8n Agents do not yet run in queue mode.
Akka gives you agents, durable state, streaming, APIs, and governance as one pre-integrated runtime. You describe the system you want, and the platform generates it, tests it, and runs it — with the runtime owning recovery so application code does not have to. Because everything runs in one runtime, a system that compiles is ready for production.
Akka keeps it running around the clock, with active-active replication across regions and automatic failover, and stands behind a contractual 99.9999% availability SLA on the entire platform.
Akka Specify builds agentic systems from your specifications and releases only what meets your definition of done.
| Dimension | With n8n | With Akka |
|---|---|---|
| Scope | Visual workflow automation and integrations across 2,000+ apps, with AI Agent nodes and n8n Agents (Preview). Durable execution, agentic scale, and streaming are layers you provision and operate. | Automation plus the whole system — agents, memory, streaming, APIs, and governance on one pre-integrated, operated runtime. |
| Availability | 99.5% uptime on Enterprise Cloud — roughly 1.8 days a year — excluding planned maintenance, with no published RTO or RPO. | 99.9999% on the entire platform — about 31 seconds a year — active-active across regions, sub-1-minute RTO, zero-byte RPO. |
| State & memory | n8n Agents (Preview) keep session memory by default and can add episodic memory across sessions with an OpenAI credential. The AI Agent node takes memory from sub-nodes, and in queue mode it needs an external store you provision. | Durable state held in memory, active-active replicated — 4 ms reads, sub-10 ms writes. |
| Durable execution | Execution state is persisted to PostgreSQL, and Redis hands each run to a worker. A stopping worker gets 30 seconds by default to finish its jobs. | Event-sourced durable execution — the runtime manages recovery and replays from the journal, with no operator intervention. |
| Governance | The Guardrails node blocks or redacts text that fails a check. An AI Agent can pause a tool call for human approval. Instance and project policies refuse a save, publish, or manual run that uses a blocked node or credential type. Enterprise adds audit logs and log streaming. | Akka Verify applies any control to any AI system and guarantees its enforcement on every action — HITL, HOTL, guardrails, evaluations — with every call recorded in tamper-evident storage. |
| Spec-driven delivery | The n8n Assistant (Preview) plans, builds, and tests a workflow or agent from a plain-language request and asks for confirmation before publishing it. | Akka Specify builds agentic systems from your specifications and releases only what meets your definition of done. |
| Model optimization | Each node or agent names its model. n8n adds OpenRouter provider routing, monthly budgets and session spend caps for agents, and metric-based evaluations that score a workflow against a dataset drawn from production runs. | Akka Optimize puts each request on the best model for the task, including smaller models trained on your data. |
| Infrastructure cost | n8n meters executions, at €20 to €667 a month billed annually for 2,500 to 40,000 executions, with custom Enterprise pricing. Each agent turn counts as one execution. Self-hosted queue mode needs PostgreSQL and Redis, which you provision and pay for separately. | One shared-compute runtime carries the same volume on up to 90% less infrastructure, at a fixed annual fee. Akka Optimize keeps improving the models on your own production traffic, so cost per task keeps falling as the system runs. |
n8n builders add Guardrails nodes and human approval steps to each workflow and agent. Admins restrict which node and credential types a workflow may use. Those controls cover workflows and agents running in n8n.
Guard, approve & log
The n8n Guardrails node checks text for jailbreak attempts, PII, secret keys, off-topic requests, and custom rules, then sends failing items to a Fail branch or redacts them. An AI Agent can pause a tool call until a person approves or denies it. Instance and project policies refuse a save, publish, or manual run that uses a blocked node or credential type.
A builder adds each Guardrails node and approval step to the workflow that needs it. The n8n security page covers SOC 2, SOC 3, and GDPR and names no AI regulation such as the EU AI Act. n8n Enterprise adds audit logs and log streaming.
Block & escalate
Risk teams govern every agentic system without waiting on its developers, and every control they apply is guaranteed to be enforced. Risk teams choose from 1,718 controls drawn from 241 regulations and frameworks. Human-in-the-loop approvals, human-on-the-loop halt switches, sanitizers, guardrails, evaluations, testing gates, and simulations all run before an action executes and block or escalate anything that does not pass.
Every call is traced automatically into petabyte-scale, tamper-evident storage, and that same trace data feeds continuous evaluations that keep running in production, right alongside your agents.
Reach for n8n when you need quick, low-code internal automations, when you are connecting apps and APIs on a visual canvas, and when triggering an LLM step inside a workflow is enough — and your team is ready to provision and operate whatever scale, durability, and governance those automations happen to touch.
Reach for Akka when you are building a production agentic system — agents, memory, streaming, APIs, and governance — and you want them pre-integrated and operated under one SLA, with durable execution, recovery, and governance built into the runtime.
The Akka Agentic AI Platform builds, runs, governs and optimizes the entire agentic system under a contractual SLA — durable execution, memory, streaming, and governance included. Tell us what you are building, and we will show you how it runs in production.
