Start from a known architecture, then adapt it.
Explore blueprint routes, reference systems, and system-design patterns without losing the ability to make them your own.
Build with the diagram in front of you.
Map the architecture before the architecture maps your roadmap.
sydep gives software developers a smart canvas for system design, AI review, simulations, and living documentation, so tradeoffs are explicit before implementation starts.

AI review findings
- Add a retry boundary between workers and the database to isolate burst failures.
- Simulate a regional failover scenario before shipping the queue fan-out.
Living documentation
sydep keeps an explainable record of the system: data flow, constraints, likely bottlenecks, and the reasoning behind the chosen shape.
Built for software developers who want stronger design decisions, not prettier boxes.
The page should prove the product quickly: sydep helps you compose a topology, compare known patterns, test a scenario, and leave with a reviewable system instead of a static sketch.
Simulate before implementation.
Stress likely scenarios and expose failure modes while changes are still cheap.
Review with AI, but keep engineering judgment in the loop.
Use AI review and documentation where they help, with clear plan limits and no inflated promises.

Read explanatory content that turns technical tradeoffs into clearer architectural decisions.
Design the system with enough clarity that implementation becomes execution, not discovery.
Use the canvas for early architecture work, browse public system-design resources for research, and upgrade only when your workflow needs the extra depth.
