3. Four questions to narrow your choice

Budget

0 → see ① OSS; can pay $10–20/mo → see ②③.

Deployment

Data stays local / need self-host → prefer OSS self-hostable.

Scenario

Code completion · monorepo refactor · generate UI · multi-agent orchestration — strengths differ; see the 'Intro' column.

Lock-in risk

Bound to a single model / editor / platform? See the 'Note' column.
