Alternatives / DataForSEO
Looking for an open source DataForSEO alternative? Only one open-source project we verified replaces part of it: OpenSERP, a self-hosted API that returns structured search results from several engines. It covers SERP data, not keyword volumes, backlinks, or the rest of DataForSEO's catalog.

We looked for open-source tools that return search engine results through an API. We verified OpenSERP's license, recent activity, stars, and self-hosting in its repository. DataForSEO also sells keyword, backlink, and on-page data that no open-source project replaces in full. See our methodology for the full criteria.
OpenSERP returns structured search results from Google, Bing, Yandex, Baidu, DuckDuckGo, and Ecosia through one endpoint, with the same JSON structure across engines and SERP features such as answer boxes. Output is available as JSON, Markdown, plain text, or NDJSON.
Multi-engine endpoints are part of the paid managed cloud. Scraping search engines can break when result pages change, and it may be restricted by their terms of use, so check them before running it at scale.
OpenSERP is MIT.
OpenSERP's last commit was in September 2026 and it has about 1,500 stars.
DataForSEO is a proprietary pay-as-you-go API, so every request costs money and the data is licensed from the provider. A self-hosted SERP API removes per-request fees for results, but scraping search engines can break when their pages change and may conflict with their terms of use.
OpenSERP is an MIT self-hosted REST API that returns structured search results from Google, Bing, Yandex, Baidu, DuckDuckGo, and Ecosia through one endpoint, including features such as answer boxes. Multi-engine endpoints are part of the paid managed cloud.
Pricing: Free to self-host; managed cloud has pay-as-you-go pricing.
