velt.dev
Link authority for velt.dev (registrable domain: velt.dev) 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 velt.dev 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 velt.dev. 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":"How is Velt different from Liveblocks?","acceptedAnswer":{"@type":"Answer","text":"Liveblocks is realtime collaboration infrastructure focused on engagement: sync, presence, and AI copilots that act on app state. Velt is review and approval infrastructure focused on control: approval workflows, review agents, audit trails, and memory, with the collaboration layer included. If your users need sign-off, records, and consent before anything changes, that is Velt."}},{"@type":"Question","name":"How is this different from the approval flow in the OpenAI Agents SDK?","acceptedAnswer":{"@type":"Answer","text":"The OpenAI SDK pauses your own agent's tool calls so a developer-defined approver can resume them. Velt is the review surface your end users see inside your product: comment threads, multi-step approval workflows, audit records, and notifications, working across humans and agents with any model or framework."}},{"@type":"Question","name":"Why not build this in-house?","acceptedAnswer":{"@type":"Answer","text":"You can, and a first version of one feature takes a quarter or two. The cost is the long tail: anchoring comments to content that moves, notification batching and preferences, permissions, offline sync, audit records, and the edge cases that make review features feel solid. That long tail is Velt's entire roadmap, with the agent layer already integrated."}},{"@type":"Question","name":"Can agents change data in my product without approval?","acceptedAnswer":{"@type":"Answer","text":"Not through Velt. Agent suggestions arrive as comments. A human approves or rejects; on approve, the change fires through your webhook with a permanent record of who allowed what. Agents never need write access to your data."}},{"@type":"Question","name":"Where does data live? Do you support self-hosting?","acceptedAnswer":{"@type":"Answer","text":"Cloud by default, with a hybrid model where content and user PII stay on your infrastructure and Velt stores only metadata, and data residency options including EU. Velt is SOC 2 Type II audited and supports HIPAA workloads."}},{"@type":"Question","name":"Which frameworks and editors does Velt support?","acceptedAnswer":{"@type":"Answer","text":"React, Next.js, Vue, Angular, and plain HTML for the SDK. Multiplayer editing and suggestions work in Tiptap, CodeMirror, and 10 other editor libraries, or in your own custom components."}},{"@type":"Question","name":"How is Velt priced?","acceptedAnswer":{"@type":"Answer","text":"Usage-based on monthly active documents (MAD): you pay for documents with review activity in a month, not per seat. There is a free tier for development and early production."}},{"@type":"Question","name":"How long does integration take?","acceptedAnswer":{"@type":"Answer","text":"Days, not quarters. Install the SDK, wrap your app, and turn on features individually. Most teams render their first comment the same day and launch their first approval workflow within a week."}},{"@type":"Question","name":"Can I migrate from Liveblocks or Cord?","acceptedAnswer":{"@type":"Answer","text":"Yes. Velt ships documented migration guides for both: /migrate-from-liveblocks-to-velt and /migrate-from-cord-to-velt. The guides cover SDK swap, data model mapping, and feature parity notes so you know what carries over and what to rebuild."}},{"@type":"Question","name":"What happens to my data when review agents run?","acceptedAnswer":{"@type":"Answer","text":"Each customer's data runs in isolated per-tenant storage. Velt does not use content from one customer to train models for another, and agent activity is never used for cross-customer model training. Audit records of every agent action are retained in your tenant only."}}]}JSON-LD block (556 bytes)

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 velt.dev and domain-level for velt.dev 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 velt.dev (including its subdomains), ranked by the linker's PageRank. The table shows the top 1,000; 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 velt.dev specifically, ranked by the linker's PageRank. The table shows the top 56; the download carries the full stored list (up to 10,000 linkers) as JSON. Click a linker for its own site profile.
