You’ve built agents before — so you already know the pain, right?
No pitch needed — you know exactly what happens when the messages pile up. This is going to sound familiar.
4 message chunks = 4 executions. No unification, no context, no protection.
Every one hits your agent — and your bill.
You're paying for every trigger
n8n, Make, Zapier — they all charge per execution. 4 messages = 4 executions = higher plan and cost.
Your agent has bad context
Users send bursts of messages. Your agent gets each one separately — bad context, wrong answers, complex workflows.
Your agent's protection is weak
Spam, token bombs, duplicate messages — they all hit your agent or LLM, at full price.
Portarus fixes all three.
Pay for one execution, not four.
Fewer executions, lower plan tier, smaller LLM bill. Portarus reduces all three — automatically.
- Your platform bill drops — 4 triggers become 1. Stay on cheaper n8n, Make, or Zapier tiers longer.
- Your LLM costs drop — One prompt instead of four. Fewer tokens processed, fewer dollars spent.
How much can you save?
This only counts execution savings — your real savings are higher.
Full context in, right answer out.
Every burst is merged into one complete prompt before it reaches your agent. No fragments, no guessing — just accurate replies.
- 4 messages → 1 prompt — One complete request instead of four fragments. Nothing gets lost.
- Right answer, first reply — No hallucinations, no "can you clarify?" — your users get it resolved.
"text": "Hi I need help", "user_id": "u_391"
"text": "My order hasn't arrived", "user_id": "u_391"
"text": "It's been 2 weeks", "user_id": "u_391"
"text": "Order #88412", "user_id": "u_391"
"text": "Hi I need help. My order hasn't arrived. It's been 2 weeks. Order #88412.", "user_id": "u_391", "merged_count": 4, "window_seconds": 8
Built-in protection — sleep tight, your agent is safe.
Portarus filters spam, duplicates, and oversized messages automatically. Only clean, valid requests reach your agent.
- Spam stopped at the gate — Per-user rate limits block floods instantly
- Duplicates dropped — User sends the same message twice? It's not repeated
- Token bombs rejected — Oversized payloads never touch your LLM
