knex vs sequelize
knex is downloaded 1.4× more often than sequelize (17,423,302 vs 12,085,864 per month), so it has the larger community and more answered questions online. knex ships 60% less gzipped JavaScript (86.2 kB vs 216.3 kB), which matters if bundle size is a priority. Both projects are actively maintained.
