LangChain / LangGraph AI agent SaaS templates. Each marketplace solution generates as a buildable LangChain / LangGraph project with the entities, workflows, and integrations specific to its vertical — not a generic auth + Stripe scaffold. LangChain / LangGraph output is a fully-wired Python AI agent application: typed LangGraph state machines per workflow, LangChain tool definitions per integration, a Flask API layer exposing agent runs as REST endpoints, persistent memory via PostgreSQL + pgvector, and Celery for long-running agent tasks. The architecture drives which tools, chains, and graphs are generated — not the other way around.
Generated as idiomatic LangChain / LangGraph: LangGraph StateGraph per domain workflow with typed state schemas · LangChain tool definitions wired to your integration points · Flask API with streaming SSE endpoint for real-time agent output · pgvector for semantic memory and retrieval-augmented generation. Plus the rest of the Python ecosystem patterns Archiet ships per stack.
Pick a vertical. The same architectural genome regenerates the solution into your stack — full domain logic, not a placeholder scaffold.

LangGraph starters typically ship a single generic scaffold — auth, Stripe, mailer, admin, deploy config. The Archiet marketplace ships vertical solutions — the entities + workflows + integrations specific to a domain are already in the box. Pick a CRM and the contact + opportunity + activity entities, the pipeline-stage workflow, the email integration, and the CSV import are all generated. Pick an ATS and the candidate + scorecard + interview-stage entities, the hiring pipeline, the calendar integration, and the offer-letter generation are all generated.
That changes the math. With a generic scaffold, you optimize for "how fast can I rebuild the same scaffold pieces every project." With a vertical solution, you optimize for "how fast can I customize the domain to this customer's specifics" — the part that's actually billable, defensible, and compounding.
Stack choice is yours. The same genome regenerates into Flask, FastAPI, Django, NestJS, Laravel, Go, Java, Rails, .NET, Tauri+Rust, SAP CAP, Dynamics 365, or LangChain / LangGraph. Pick whichever your team already runs, or whichever your enterprise client mandates. Pick LangChain/LangGraph when your architecture includes AI agents, RAG pipelines, or multi-step reasoning workflows. Archiet generates the graph topology from your business requirements — you get a production agent system, not a Jupyter notebook demo.
