Make the call yourself: two real design decisions, each with its options, its trade-offs and what was actually built.
Each decision offers two or three designs. Choose one to see how the system would flow, how it compares on the trade-offs that mattered, and the reasoning behind it. Then read what was actually built.
The comparisons are qualitative. They show the shape of each trade-off, not a measurement of it.
Decision 01
A coding agent has changed an API endpoint. Before it merges, someone has to be confident the running service still behaves.
Fast, but the tests share the author's assumptions. If the agent misunderstood the requirement, its tests encode the same misunderstanding and pass.
This is the problem Dino exists to solve: independent, deterministic verification of running APIs, with a sealed verdict a pipeline can gate on.
Deterministic verificationDecision 02
A creator wants their finished episode to feel like a live event: everyone watching together, chat alongside, no skipping ahead.
Genuinely live, but it adds a second media pipeline to run and pay for, for content that already exists as a finished file.
At Circo the design chose simulated live from a dynamic HLS manifest. Managed live encoders were evaluated and set aside for the first version.
