v2026.05 · Agentic platform on AWS

Build agentic AI and production APIs — without the infrastructure.

NoStackAI is the enterprise platform where your agents live, act on real data, expose as APIs, and run in multi-tenant isolation. Configure, deploy, and scale — no backend code required.

Section 01 · Agentic AI

Build AI agents that actually do things.

NoStackAI's Logic Blocks are your native agentic layer. An agent is a pipeline of steps — fetch data, reason with an LLM, call a tool, loop, decide — all configured in a visual builder, executed as a production API endpoint. No LangChain setup. No infra. No multi-tenancy to solve.

ai_call

Classify, summarize, extract

Single-shot LLM steps for translation, generation, structured extraction.

ai_agent

Tool-use loop

Model calls your other APIs as tools — bounded, observable, deterministic.

ai_compare

Run providers in parallel

Fan out to Anthropic, OpenAI, Gemini at once — return the ranked output.

get_entity · list_entities

Operate on live data

Agents read and write your real entities, with ACL and tenant scoping enforced.

webhook

Call any HTTPS endpoint

Map request/response. Bring your own Lambda, Stripe, internal service.

condition · loop

Branch and iterate

Real control flow. Decision trees and retries without writing code.

Section 02 · APIs without code

Your entities, your APIs — configured, not coded.

Define your data model in API Studio. NoStackAI generates GET / LIST / CREATE / UPDATE / DELETE endpoints instantly, with ACL enforcement, field encryption, multi-tenant scoping, and OpenSearch-powered list queries — all from a config record, not a Lambda.

  • IAM-like ACL policies stored in DynamoDB, evaluated per request
  • Field-level AES-256 encryption for passwords, PII, and secrets
  • OpenSearch query layer for flexible filters, pagination, owner scoping
  • Test and production environments with one-click deployment pipeline

Section 03 · Escape hatch

Write code when config isn't enough.

Logic Blocks support webhook steps to call any external service or your own Lambda. Bring your own AI provider keys. Override model defaults per tenant. NoStackAI is the platform — your code runs inside it, not the other way around.

  • Webhook steps call any HTTPS endpoint with request/response mapping
  • Per-tenant AI provider key override (Anthropic, OpenAI, Gemini)
  • Connector steps for pre-built integrations with tenant credential management
  • Formula and transform steps for data reshaping without code
How it works

Three steps to production.

From a blank workspace to a tenant-isolated agentic API — without spinning up a single Lambda.

01 Model

Model your data

Define entities and fields in API Studio. CRUD APIs, ACL, and search are generated automatically.

02 Compose

Build your logic

Chain steps into a Logic Block: fetch data, call an AI, apply conditions, call webhooks.

03 Ship

Deploy and scale

Publish to production with one click. Each customer gets their own isolated AWS stack. NoStackAI handles the rest.

Compliance & reliability

Enterprise-grade from day one.

Per-customer AWS stacks. Encrypted fields. Independent control plane. The boring infrastructure problems — already solved.

GDPR Compliant

Data residency controls, field-level encryption, right-to-erasure support.

Disaster Recovery

Multi-region app stacks, independent control plane, zero shared data between customers.

AES-256 Encryption

Encrypted at rest (SSM KMS), encrypted in transit, write-only fields never returned in responses.

Per-Customer Isolation

Every org runs its own DynamoDB tables and Lambda stack. No shared database, no noisy neighbor.

vs. the alternatives

Other tools give you pieces. NoStackAI is the complete platform.

The honest comparison. Where we win, where others are also fine, and where you'd be wiring it yourself.
