Google OR-Tools vehicle routing
Use and fit
A developer can model vehicle capacities, stop time windows and dropped visits. Requires trustworthy travel matrices and actual constraints; it can produce a good feasible answer without proving global optimality. Good advanced option when ready-made field-service routing is insufficient.
Cost and access
Free solver; developer time, compute and external mapping/geocoding services may cost money.
Popularity and evidence
Official GitHub snapshot showed 14.1k stars and 2.5k forks. Repository attention is not a count of successful small-business deployments.
Reuse and package decision
Apache-2.0 repository. No solver code or library distributed here.
Tools were not installed or operationally tested. Prices/counts may change. This is a research summary, not the product, connection, license grant or proof of field competence.
