Circle.so Reviews

The Top Free and Paid Teachable Alternatives For Creators
While Circle offers video and social integrations, itโ€™s missing quite a number of features on the sales and market side. For example, it doesnโ€™t allow you to create in-app sales funnels with customizable landing pages and checkout for selling community memberships. It also doesnโ€™t offer any native or third-party email marketing tools.
20 Telegram Alternatives to Chat With in 2024
Like Mighty Networks, Circle is a community platform that can work as an alternative to Telegram. It has a combination of forum, course, and livestreaming features to build a community around a shared interest. And your members can share text and video content.

Circle.so mentions (32)

  • Collaboration Circles for Developers (2026)
    Circle.so is a platform designed for online communities, with sub-groups, private spaces, etc. Ideal for creating private circles: you could set up an "Angular/React/AI circle" of 5 people and use Circle's functionalities to schedule meetings, chats, shared files. Advantage: more structured, ideal for your 5-person model. Limitation: may have a cost or require configuration. - Source: dev.to / 9 months ago

  • Tell HN: DuckDuckGo Search Results have jumped the shark
    Https://circle.so/pricing/ I would guess even if DDG protects your privacy, it would use information (perhaps search and or site history) the browser is broadcasting regardless to filter results it pipes to the end point. For example I never see quora results (honestly it's been some years so I'd forgotten they existed still) as some members in this thread were annoyed with and paid to be done with them ...

  • Which nocode tool to build an online academy?
    What is the reason you are trying to go custom? https://circle.so this is probably the best platform I have seen. Big and small companies use it (even webflow) so it has great adoption works well. I would stay away from a custom solution when there are wonderful tools like circle out there.

  • The Seven Engineering Problems That Make Real-Time Enterprise Sync Almost Impossible
    Three years and one Y Combinator batch later, Stacksync syncs millions of records across 200+ enterprise systems with sub-second latency. I want to explain why this problem is as hard as it is, because most engineering teams underestimate it until they're six months into a failing project. - Source: dev.to / 4 months ago
