As answered by people managing Vivaldi and Sourcey.
Sourcey's answer:
Sourcey ties startup offers and Agent Readiness findings to source evidence and versioned releases. A report card describes one agent task, its observed result, blockers, and unknowns. Offer records keep the vendor’s terms and eligibility caveats visible. The public record is free to read through the website, JSON, API, and MCP.
Sourcey's answer:
Founders comparing startup offers, developers evaluating whether an agent can complete a specific task with a service, and agents that consume the public record through HTTP or MCP.
Sourcey's answer:
Choose Sourcey when you need the original source behind an offer or a task-level account of what an agent could actually do. It shows uncertainty and release history alongside the finding. Sourcey does not apply for offers or redeem credits on a founder’s behalf.

And there's plenty more to like about Vivaldi. Its unique tab management tool allows you to stack multiple tab rows on top of each other, so you can group certain websites to clear clutter and make more room on your...
Compared to Brave, Vivaldi lacks privacy features, but the huge extension support compensates for that. In my experience, both Brave and Vivaldi offer the same browsing speed, and the system impact was also equal.
Vivaldi's RSS reader is new, and features are somewhat limited. For example, it doesn't handle some of the extras that other services do, like newsletters and Facebook pages. If you just want a simple reader to...

The solution for the (as of yet) small group of people who cares about these things is very simple: community driven forks. With the bonus that you also get a set of great (and per fork different yet handy) features. These include:... - Source: Hacker News / 10 months ago
Last, but not least in my journey to find the perfect browser for me is Vivaldi. This browser was developed back in 2015 by a former Opera co-founder and markets itself to primarily power users. The browser strives to be the all-in-one... - Source: dev.to / 11 months ago
I use Vivaldi[1], it seems to work fairly well. Also has built-int adblocker although I'm not sure how good it is compared to Ublock or others. [1] https://vivaldi.com/. - Source: Hacker News / over 1 year ago
For example, from the Sourcey agent-readiness release Release_id sha256:371cbf65650abf5756c967b1f1da9df607be4b1bb0c0b93aaf2dcf0a36e75d3e (artifact_sha256:67c4edef061ca4ea60cef1e1bc246d2ce0b7d6b12e227c0811d7405d3d0a63ac, Effective... - Source: dev.to / 2 days ago
Doing all this by hand for every candidate got old fast, so now I lean on Sourcey, a registry that tracks exactly this. It publishes report cards that grade whether an agent can actually sign up, pay, and operate a service on its own,... - Source: dev.to / 14 days ago
Machine-readable acceptance criteria are worth more to an agent than documentation quality. A page that says we accept X, with a named artifact and its schema, is worth ten pages of tutorials, because it lets the agent verify a claim... - Source: dev.to / 29 days ago
