| Dimension | n8n | Akka |
|---|---|---|
| What it is | A visual workflow-automation platform with AI Agent nodes | A full-stack agentic systems platform |
| Scope | Workflow automation and integrations; agentic scale, durable execution, and governance are the customer's burden | Orchestration, agents, memory, streaming, APIs, observability, and governance on one runtime |
| Availability SLA | 99.5% uptime (Enterprise Cloud), excluding planned maintenance | 99.9999% — entire platform, backed by indemnities |
| HA / DR | Queue mode + multi-main, Redis required; no published RTO/RPO or active-active multi-region guarantee | Sub-1-minute RTO; zero-byte RPO; active-active across regions |

n8n is a visual workflow-automation platform that connects 400+ apps and APIs, with AI Agent nodes added on top. It is excellent for integrations and internal automations, and self-hosting gives teams full control of their data. A production agentic system needs more than node-based automation — durable execution, horizontal agentic scale, durable memory, streaming, and runtime governance — and n8n leaves those to you.
| Capability | n8n | Akka |
|---|---|---|
| Visual workflow automation + integrations | Yes (400+ integrations) | Programmatic; integrations via code |
| Native AI agents (tools, handoffs, streaming) | AI Agent node on LangChain JS | Built in |
| Durable execution / replay | PostgreSQL-persisted; no deterministic replay | Event-sourced, runtime-managed recovery |
| Durable memory | Bolt-on sub-nodes; external store | Built in, 4ms / sub-10ms |
| Real-time streaming | None native | Built in, backpressured, petabyte-scale |
| Inline governance / policy enforcement | None | Inline, runtime-embedded |
| Pre-production governance | None | Classification, sign-offs, sealed posture |
n8n's AI Agent node is a wrapper over the LangChain JavaScript framework. It is ideal for triggering an LLM step inside an automation; it is not an agent runtime engineered for unattended, process-attached execution at scale.
n8n Enterprise Cloud publishes a 99.5% uptime commitment (excluding planned maintenance during 10am–5pm German time) — roughly 1.8 days of allowed downtime per year. Akka's contractual SLA is 99.9999% — about 31 seconds per year — across the entire platform, backed by indemnities.
| Metric | n8n | Akka |
|---|---|---|
| Availability SLA | 99.5% (Enterprise Cloud) | 99.9999% |
| Allowed downtime / year | ~1.8 days | ~31 seconds |
| RTO | Not published | Sub-1 minute |
| RPO | Not published | Zero byte |
| HA model | Queue mode + multi-main; Redis + PostgreSQL required | Active-active across regions |
| Durable execution | PostgreSQL-persisted; crashed-worker runs can be marked "crashed" | Event-sourced, replayable from the journal |
To scale horizontally, n8n runs in queue mode: a Redis message broker (Bull queue) distributes executions to worker processes, PostgreSQL is mandatory, and multiple "main" instances provide availability. This is capable for automation throughput, but n8n provides no deterministic durable-execution substrate — when a worker dies mid-execution, in-flight runs can be marked "crashed" rather than transparently replayed, and recovery is the operator's responsibility. Akka's actor-based runtime runs 4KB actors at 200M actors/core across clusters up to 1M nodes; state is durable in-memory and replayable from the event journal; the runtime owns recovery, so application code does not have to.
AI systems built with Akka are up to 90% cheaper to operate than Python-based systems — a function of the infrastructure required for the same agentic transaction volume, not list price. The drivers are actor concurrency (~10T tokens/core/year vs ~2T; ~80% less compute than Python frameworks; Manulife: up to 300% more concurrency, 30–50% faster processing after porting from Python), shared compute, and micro-checkpointing.
n8n Cloud bills per execution (€24/mo Starter / 2,500 executions, up to €800/mo Business / 40,000 executions; Enterprise custom), and that meter covers automation only. Memory, streaming, agent infrastructure, and the database sit outside it — provisioned and operated by you when self-hosted. Akka runs all of it on one shared-compute runtime for a fixed annual fee finance can forecast.
n8n Enterprise provides audit logs and log streaming — useful operational telemetry. It provides no AI governance for production agents: no inline policy enforcement, no decision explainability, no human pause/override of a running agent, no immutable interaction ledger, no pre-deployment classification, and no sealed audit artifact. The compliance burden stays with the customer.
| Violation | Maximum Fine |
|---|---|
| Prohibited AI practices (Art. 5) | EUR 35M or 7% global turnover |
| High-risk obligations (Art. 9-15) | EUR 15M or 3% global turnover |
High-risk AI carries a 10-year logging-retention obligation (Art. 72).
The EU AI Act is enforceable now (prohibited practices since Feb 2025, high-risk since Aug 2025). Akka governs at the runtime: inline guardrails, policies, LLMs-as-a-judge, and sanitizers; hash-chained immutable evidence; HITL/HOTL control; pre-deployment classification against 189 regulations and 962 controls (574 of which carry a financial penalty); multi-persona sign-offs; a sealed Governance Posture Package; and Akka Verify proving conformance from the running system. Governance n8n leaves to you, Akka enforces inline.
Building on n8n means a workflow author wiring nodes on a canvas; there is no co-equal, independent governance lifecycle and no path for a risk officer to author and version enforceable safeguards. Akka runs two independent lifecycles on one platform via Akka Specify:
The build lifecycle and the governance lifecycle are versioned and tested independently, by different audiences — an audience and a workflow n8n has no equivalent for.
n8n has no native streaming engine; real-time pipelines and agent feedback loops are provisioned separately. Akka's streaming is built into the runtime — continuous, backpressured, petabyte-scale, in-memory, with no external broker — powering both agent feedback loops and high-throughput data processing (the engine behind Tubi's real-time hyper-personalization at 5 billion tokens per second).

| License | Sustainable Use License — fair-code, source-available, not open source; internal-business-purpose only; reselling/hosting n8n as a service prohibited; embedding requires the n8n Embed commercial license | BSL; deploy on Akka cloud, hyperscaler VPC, your Kubernetes, on-prem, or sovereign cloud; portable specs |
n8n is well-funded and growing fast — the decision is scope and accountability. n8n gives you a best-in-class automation canvas to integrate apps and trigger AI steps; Akka gives you the agentic platform, and owns the SLA, the durability, and the governance. The Sustainable Use License is also a procurement gate worth reading early: source-available but commercially restricted, with no right to offer n8n as a hosted service and a separate commercial license required to embed it.
