Tech Stack

Choose your startup tech stack. See it as architecture.

Describe your product and the AI recommends a tech stack tailored to your use case - then generates architecture diagrams showing how every component connects.

How it works

Visualize your entire tech stack as an architecture diagram and understand how every technology connects.

1

List your technologies

Enter the frameworks, databases, APIs, and services your startup uses. Include everything from your frontend framework to your payment processor — the AI understands hundreds of technologies and how they typically interact in production systems.

2

AI maps your tech stack

The system generates a comprehensive architecture diagram showing how each technology fits into your overall system. Frontend, backend, data layer, infrastructure, and third-party services are organized into clear layers with labeled connections showing data flow and dependencies.

3

See how components connect

Explore the relationships between your technologies — which services depend on each other, where single points of failure exist, and how data flows through the system. Use this visibility to make informed decisions about scaling, migration, and vendor changes.

Use cases

Tech stack visualization helps teams make better technology decisions at every stage.

Tech stack documentation

Create a single source of truth for every technology in your stack. Instead of scattered wiki pages and outdated READMEs, maintain one living diagram that shows what you use, why you chose it, and how it connects.

New hire tech overview

Give every new engineer a visual map of the entire technology landscape on their first day. A tech stack diagram answers the “what do we use and why” question that every hire asks during their first week.

Technology migration planning

Visualize the before and after states of a technology migration. See which services are affected, which APIs need updating, and where the migration boundaries should be drawn to minimize disruption to production.

Vendor comparison

Compare how different vendor choices affect your architecture. Generate side-by-side diagrams showing the integration complexity of competing services before committing to contracts and building integrations.

Build-vs-buy analysis

Visualize the architectural impact of building a component in-house versus adopting a third-party service. See the coupling, the API surface, and the maintenance burden of each option in a clear diagram.

Annual tech review

Conduct yearly tech stack audits with a current architecture diagram as the foundation. Identify technologies that have become liabilities, spot redundant services, and plan the next year's technical investments with clarity.

Why tech stack visibility matters

Tech stack decisions compound over years. Every framework, database, and third-party service you adopt becomes a load-bearing wall in your architecture. Without clear documentation of what you chose and why, teams end up relitigating the same technology debates every quarter. A visual tech stack map gives every engineer — from the founding team to the newest hire — the context they need to make informed decisions instead of guessing.

The hidden cost of an undocumented tech stack is not just confusion — it's duplication. When engineers don't know what tools already exist in the system, they build new ones. When teams can't see shared dependencies, they introduce conflicting versions. A tech stack diagram exposes these overlaps and gaps instantly, turning invisible waste into visible optimization opportunities that can save thousands of dollars in infrastructure costs.

As startups grow from five engineers to fifty, the tech stack evolves from something everyone knows intuitively into something no single person fully understands. That transition is where documentation becomes critical. A living tech stack diagram — one that updates as the architecture changes — ensures that institutional knowledge doesn't evaporate when early employees leave. It becomes the technical memory of the company, preserving the rationale behind every major technology decision.
