Research analysis

Rule-based research guidance derived from the source record. Audience and commercial demand require validation.

Project record

The record contains the title “Show HN: OpenSwells – free, open-source surf forecasts for 5,800 spots” but no substantive source summary.

Observed adoption & comparisons

Source votes: 2 votes (Nov 12, 2026 UTC; cumulative since publication); previous same-scope observation: 2 (Nov 12, 2026 UTC). These observations do not establish demand growth.

Adoption decision

Evaluate it against the tool or manual workflow it would replace. The stored record supports discovery; it does not yet establish reliability, lower operating cost or commercial adoption.

Unverified requirements

Not verified: license permissions, required hardware, installation steps, maintenance status and a representative task with its failure cases.

Next test

Choose one real task and a current alternative. Record the commit, environment, input, output, elapsed time and failure behavior; retain the result before recommending adoption.
