BestSearch vs Tavily, compared line by line

/comparison

Tavily comparison, feature by feature

Everything a Tavily integration relies on is preserved. The only deltas are in your favor: price, key isolation, and where the service can run.

Prices are list prices per credit in USD. Tavily and its logo are trademarks of their respective owner; BestSearch is an independent, compatible alternative and is not affiliated with Tavily.

/when-to-pick-which

When to pick which

Stick with Tavily if you are already deep in their ecosystem, your contract pricing is favorable, and you have no appetite to change a working integration. Pick BestSearch if cost matters at volume, you want each customer or environment on its own isolated key, or you need the option to self-host on your own infrastructure. Because the API surface is identical, this is not a one-way door: you can repoint the base URL, run the same queries against both, and keep whichever delivers better cost-per-result for your workload.

/one-line-migration

Switching is one line

Keep your SDK, parameters, and response parsing. Repoint the base URL and your existing Tavily code runs unchanged against BestSearch.

from tavily import TavilyClient

# Before — Tavily, $0.008/credit
# client = TavilyClient(api_key="tvly-...")

# After — BestSearch, $0.004/credit. Same client, same calls.
client = TavilyClient(
    api_key="bsk-...",
    base_url="https://app.websearchapi.tech",   # <- the one line you change
)

# Identical request, identical response shape
res = client.search("best vector database 2026", search_depth="advanced")
print(res["results"][0]["url"])

/faq

BestSearch vs Tavily, answered

• How is BestSearch different from Tavily?

  BestSearch exposes the exact same /search, /extract, /crawl, /map, /research endpoints with identical request and response shapes and the same credit model as Tavily. The difference is price ($0.004 per credit vs Tavily’s $0.008) plus per-client key isolation, a self-hostable deployment, and an open-source core.

• Is migrating from Tavily to BestSearch really one line?

  Yes. Because the endpoints and payloads match Tavily one-to-one, you only repoint your base URL to https://app.websearchapi.tech and swap in your BestSearch key. Your existing SDK calls, parameters, and response parsing keep working unchanged.

• Are the search results the same quality as Tavily?

  BestSearch returns the same response structure Tavily clients expect across search, extract, crawl, map, and research. We do not publish synthetic benchmarks — the honest test is to point your own queries at both and compare, which the one-line switch makes trivial.

• Why is BestSearch half the price?

  Pricing is the wedge. We list credits at $0.004 each — exactly half of Tavily’s $0.008 — using the same credit accounting so your per-call cost maps directly. No tiers to decode, no surprise minimums.
