Firecrawl vs mlr3tuningspaces
A side-by-side editorial comparison of Firecrawl and mlr3tuningspaces — release velocity, themes, recent moves, and the top alternatives to consider.
Firecrawl vs mlr3tuningspaces: at a glance
What is Firecrawl?
Firecrawl stopped selling pages and started selling answers — now it is giving the corpus away.
Firecrawl has spent four months converting a scraping API into an answer-retrieval layer for agents. Question, Highlights and the excerpt-scoring rebuild of /search all trade full-page delivery for the specific lines that answer a query, each pitched on token cost rather than coverage. Alongside that it has started owning corpora outright — the Research Index now spans 3M+ arXiv papers and 41M+ life-sciences papers — and /monitor turns crawling into a subscribable event stream.
What is mlr3tuningspaces?
A curated catalogue of published hyperparameter search spaces, now reaching deep neural networks
mlr3tuningspaces packages hyperparameter search spaces taken from published benchmark studies so mlr3 users can tune against a citable range instead of inventing bounds. Its release history is steady catalogue growth punctuated by compatibility bumps across the mlr3 stack. 0.7.0 adds spaces for deep neural networks from Gorishniy, Rubachev, Khrulkov and Babenko (2021) alongside mlr3 1.7.2 compatibility.

Firecrawl stopped selling pages and started selling answers — now it is giving the corpus away.
◆ Current state
Firecrawl has spent four months converting a scraping API into an answer-retrieval layer for agents. Question, Highlights and the excerpt-scoring rebuild of /search all trade full-page delivery for the specific lines that answer a query, each pitched on token cost rather than coverage. Alongside that it has started owning corpora outright — the Research Index now spans 3M+ arXiv papers and 41M+ life-sciences papers — and /monitor turns crawling into a subscribable event stream.
◆ Where it's heading
The centre of gravity is moving from generic crawl infrastructure to curated indexes with published benchmark numbers attached, and now to giving those indexes away. Every recent release argues the same point in a different register: the crawler should return the smallest correct thing, and Firecrawl should already have it indexed. Free access to Research Index converts a metered data product into a distribution channel for the paid scraping and monitoring endpoints around it.
◆ Prediction
Expect a third vertical index after AI/ML and life sciences — the pattern of a benchmark claim, daily refresh and API-plus-MCP-plus-CLI availability is now a repeatable template. Whether the free tier stays free once query volume lands is the open question the entries do not answer.

A curated catalogue of published hyperparameter search spaces, now reaching deep neural networks
◆ Current state
mlr3tuningspaces packages hyperparameter search spaces taken from published benchmark studies so mlr3 users can tune against a citable range instead of inventing bounds. Its release history is steady catalogue growth punctuated by compatibility bumps across the mlr3 stack. 0.7.0 adds spaces for deep neural networks from Gorishniy, Rubachev, Khrulkov and Babenko (2021) alongside mlr3 1.7.2 compatibility.
◆ Where it's heading
The catalogue keeps widening one paper at a time — Kühn (2018) rbv1 spaces in 0.4.0, a corrected attribution to Binder, Pfisterer and Bischl (2020) for rbv2 in the same release, and now a deep-learning set in 0.7.0. That growth is bounded by forces outside the package: 0.6.0 had to delete the `kknn` spaces outright when the underlying package left CRAN, a breaking change driven by upstream availability rather than any design decision here.
◆ Prediction
Expect further spaces from newly published benchmark papers rather than a change in what the package does, since every feature release in this window has been of that form. Whether the deep-learning spaces get extended depends on learner support elsewhere in mlr3, which these entries do not cover.
