AI Agent Infrastructure
Building AI agents from scratch means managing 6+ services, spending weeks on infrastructure, and ongoing maintenance. There's a better way.
The DIY AI Agent Stack
Here's what you need to build and maintain yourself:
LLM API
$0.15-15/1M tokensOpenAI / Anthropic
Core AI capability
Vector Database
$70-700/moPinecone / Weaviate / Qdrant
For RAG and knowledge bases
WhatsApp Integration
Setup + per-message feesMeta Cloud API / Twilio
Business API complexity
SMS Provider
$0.0079+/messageTwilio / Vonage
Another integration to maintain
Session Management
$25-200/moRedis / DynamoDB
Track conversation state
Orchestration Framework
Dev timeLangChain / Custom
Tool calling, routing, memory
Hosting & Infra
$50-500/moAWS / GCP / Vercel
Run your agent 24/7
Total: 6-10 services, $500-2000+/mo, 200+ dev hours
And that's just to get started. Maintenance, scaling, and updates are ongoing.

| Vector DB setup | Provision, configure, embed | Upload docs, done |
| Session persistence | Build custom solution | Built-in, automatic |
| Human handoff | Build routing logic | One-click transfer step |
| Multi-channel support | Integrate each separately | Same agent, all channels |
| Ongoing maintenance | Your responsibility | We handle it |
The Hidden Costs of DIY
Infrastructure costs are just the beginning.
Developer Time
200-500+ hours to build, test, and deploy. At $100/hr, that's $20,000-$50,000 before your first customer conversation.
Maintenance Burden
API changes, security patches, scaling issues. Ongoing costs of 20-40 hours/month to keep everything running.
Integration Hell
WhatsApp Business API has complex webhooks, verification flows, and message templates. SMS requires 10DLC registration. Each channel is a project.
Compliance & Security
PII handling, data retention, GDPR compliance, audit logs. Building this properly takes significant effort.

Common Questions
What if I need custom features Zavu doesn't have?
Our tool integration lets you connect any API via webhooks. Your agent can call your custom endpoints, query your databases, or integrate with any system you need. For truly custom needs, our API gives you full control.
Can I migrate from my existing DIY setup?
Yes. Most developers migrate in a few hours. Export your knowledge base content, recreate your flows in our visual builder, and point your webhooks to our endpoints. We can help with migration.
What about vendor lock-in?
You own your data. Export knowledge bases, conversation history, and configurations anytime. LLM calls go through standard provider APIs - switch providers with a config change. No proprietary formats.
Is it really faster than building myself?
We've seen teams go from zero to production agent in under a day. Compare that to 2-8 weeks for a DIY build. The time savings compound: no maintenance, no scaling issues, no integration headaches.
Build Agents, Not Infrastructure
Focus on what makes your agent unique. Let us handle the messaging, vector DBs, session management, and multi-channel complexity.
