Duolingo vs SAP

Duolingo and SAP (SAP SE, a global software company, is one of the largest vendors of ERP and other enterprise applications.) both appear on the Smoower Developer Ecosystem Index.

SAP (rank #122) holds a modest lead over Duolingo (rank #338) on the overall Smoower ecosystem score (54 vs 43). The gap of 11 points reflects composite signals across code, docs, community and reach.

On code quality (the state of repositories, tests, releases and polish), SAP is clearly ahead of Duolingo. On education (docs, guides and learning material for developers), SAP is ahead of Duolingo. On community (issue response, PR reviews and discussion health), SAP is ahead of Duolingo. On reach (how visible the ecosystem is beyond its own repos), Duolingo is clearly ahead of SAP. On momentum (release cadence and how fast the ecosystem moves), SAP is ahead of Duolingo.

Duolingo carries 1,721 GitHub stars across 12 public repos, with 8 repositories active in the last 90 days and 11 external contributors on record. SAP shows 12,850 stars across 309 public repos, 96 active in the last 90 days and 60 external contributors. The star gap on its own does not decide the comparison, but SAP's footprint is roughly 7.5x larger, which usually shows up in downstream signals like inbound issues and third party integrations.
