prefect.io
Link authority for prefect.io (registrable domain: prefect.io) from the Common Crawl web graph: PageRank and harmonic centrality history since 2017, current scores, and the site's top backlink sources.
Web-graph authority (0-100)
Domain scores measure prefect.io as a whole: every subdomain's links rolled up into one node of Common Crawl's domain-level web graph. Host scores measure the exact hostname prefect.io. WWW scores cover the www variant of that hostname, which the graph tracks as its own entry since January 2026 (before that, www and bare host were merged). A big gap between domain and host usually means the domain's authority lives on other subdomains. PageRank is link-endorsement authority: how much weight the sites linking here carry themselves. Harmonic centrality measures reach: how close this site sits to the rest of the web when following links, which favors broadly connected sites over ones boosted by a few heavy linkers. All are normalized 0 to 100 within each crawl snapshot; a dash means that series does not exist for this site.

{"@context":"https://schema.org","@type":"FAQPage","mainEntity":[{"@type":"Question","name":"What is Prefect?","acceptedAnswer":{"@type":"Answer","text":"Prefect is a workflow orchestration platform for data, ML, and agents. You write workflows as plain Python, and Prefect runs them durably in production: scheduling, retries, caching, and recovery are part of the platform rather than code you maintain. The open-source framework and Prefect Cloud share the same core engine."}},{"@type":"Question","name":"Can my coding agent write Prefect workflows?","acceptedAnswer":{"@type":"Answer","text":"Yes. A Prefect workflow is ordinary Python with two decorators, so any coding agent that writes Python can produce a working flow, add retries, and deploy it without learning a DSL. Your engineers review and own the result, and the same is true for humans: if you can write a Python function, you can ship a Prefect flow."}},{"@type":"Question","name":"How is Prefect different from Airflow?","acceptedAnswer":{"@type":"Answer","text":"Three differences do most of the work. Workflows are plain Python functions that can branch, loop, and create tasks at runtime, rather than DAGs declared up front. Durable execution is built into the engine, so retries, state, and crash recovery are not code you write. And with Prefect Cloud there is no scheduler for your team to host, upgrade, or page anyone about."}},{"@type":"Question","name":"Do I have to run any infrastructure?","acceptedAnswer":{"@type":"Answer","text":"Only if you want to. Prefect Serverless runs flows on managed compute, so you can start with zero infrastructure. Teams with stricter requirements use the hybrid model instead: lightweight workers inside your environment run your code where your data already lives, while the control plane handles scheduling and visibility. That split is what clears most security reviews."}},{"@type":"Question","name":"Is Prefect open source?","acceptedAnswer":{"@type":"Answer","text":"Yes. The Prefect framework is open source under the Apache 2.0 license, and it is the same engine Prefect Cloud runs. Cloud adds the managed control plane, enterprise authentication, and scale on top; it does not fork the framework."}},{"@type":"Question","name":"What does the Dagster Labs acquisition mean for Prefect?","acceptedAnswer":{"@type":"Answer","text":"Prefect acquired Dagster Labs in July 2026, bringing together two leading orchestration products. Nothing changes for users of either product: Dagster keeps its name and open-source license, and no action is required of any customer. The full announcement is at prefect.io/prefect-acquires-dagster."}}]}Authority over time
Every Common Crawl web-graph release since 2017, roughly quarterly. The domain series goes back to 2017; Common Crawl only began publishing the host-level graph in 2020, so host lines start there. Click a legend entry to show or hide that line. Flat lines are normal for established sites; watch for sustained rises or drops, which track real gains or losses in who links here.
A note on www: through the end of 2025 the source web graph merged www and non-www hostnames into the bare name, so one host line covers both. Starting in January 2026 the graph splits them into separate entries, which is why www can carry its own scores going forward.
Backlink counts
Unique linking domains seen in Common Crawl's link graphs. This is a different dataset than the 0-100 authority scores above: these are raw counts, host-level for prefect.io and domain-level for prefect.io with all its subdomains combined. Common Crawl covers a large sample of the web, not all of it, so treat counts as comparable between sites rather than absolute totals.
Top backlinks in the domain graph
Common Crawl publishes two link graphs. The DOMAIN graph connects whole domains: every link from any page of one domain to any page of another. This table shows the highest-authority domains linking to prefect.io (including its subdomains), ranked by the linker's PageRank. The table shows the top 817; the download carries the full stored list (up to 10,000 linkers) as JSON. Click a linker for its own site profile.
Top backlinks in the host graph
The HOST graph connects exact hostnames, so subdomains count separately. This table shows the highest-authority hosts linking to prefect.io specifically, ranked by the linker's PageRank. The table shows the top 113; the download carries the full stored list (up to 10,000 linkers) as JSON. Click a linker for its own site profile.
