Firecrawl vs mlr3benchmark: 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 mlr3benchmark?
A small mlr3 add-on for comparing learners, spending most releases making its statistics honest.
mlr3benchmark handles the statistical end of the mlr3 ecosystem: aggregating benchmark results into BenchmarkAggr objects, running Friedman and post-hoc tests across them, and drawing critical difference plots. The four visible releases span two years and are dominated by correctness work on those tests and plots rather than new comparison methods. The package changed maintainer at 0.1.4 and has not shipped since.

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.
mlr3benchmark
0.0AI-ASSISTANTS
A small mlr3 add-on for comparing learners, spending most releases making its statistics honest.
◆ Current state
mlr3benchmark handles the statistical end of the mlr3 ecosystem: aggregating benchmark results into BenchmarkAggr objects, running Friedman and post-hoc tests across them, and drawing critical difference plots. The four visible releases span two years and are dominated by correctness work on those tests and plots rather than new comparison methods. The package changed maintainer at 0.1.4 and has not shipped since.
◆ Where it's heading
The arc is a package tightening the gap between what its plots show and what its tests actually support. Overlapping bars in CD plots were producing misleading comparisons in 0.1.1; construction was loosened so column naming stopped being rigid; then 0.1.2 tightened the other way, requiring factors rather than silently coercing them. By 0.1.4 the friedman_global escape hatch lets users proceed past a non-significant global test deliberately rather than being blocked by it.
◆ Prediction
The maintainer handover at 0.1.4 with no release since is the clearest signal in these entries, and it points to continuity work rather than expansion. Nothing here indicates which additional post-hoc tests, if any, are planned.
