PoweredBy vs BuiltWith, a free alternative
BuiltWith is the best-known technology profiler, and it paywalls the parts that matter (lists, history, stats) behind $295-995/month plans. PoweredBy gives those away free.
| Feature | PoweredBy | BuiltWith |
|---|---|---|
| Single-site lookup | ✓ free | ✓ free |
| Full lists of sites using a technology | ✓ free, uncapped | ✗ paid ($295+/mo) |
| Technology history / timeline | ✓ free, back to 2018 | ✗ paid |
| Market-share statistics | ✓ free | partial / paid |
| CSV downloads | ✓ free (top 10K) | ✗ paid |
| Account required | no | yes for most data |
| Contact/email harvesting | never | yes (a core product) |
The short version: If you need a single lookup, both work. If you need lists, history, or stats (the things BuiltWith charges for), PoweredBy is free and account-free.
