It's built mobile-first and works in 12 languages: English, German, French, Spanish, Italian, Portuguese, Dutch, Polish, Turkish, Indonesian, Vietnamese, Arabic.
Recurring polls support weekly or monthly meetings with one shared link. Calendar export to Google, Apple, and Outlook via .ics file. ActionCable-powered live updates mean votes appear instantly as people respond.

SyncWhen's answer:
SyncWhen is the only free scheduling poll where both creators and voters skip signup, voting is true yes/maybe/no (not just yes/no), and results update live via WebSocket โ while staying completely ad-free. It also ships in 12 languages out of the box, including German, Arabic, and Vietnamese, which is rare in this category.
SyncWhen's answer:
Three reasons: (1) zero friction โ no one needs an account, not the organizer, not the participants; (2) real-time results โ votes appear instantly without page refresh; (3) it's genuinely free โ no ads, no paywalled features, no data sales. Competitors like Doodle lock yes/maybe/no voting, ad removal, and calendar sync behind $6.95+/month paywalls. SyncWhen includes all of it for free.
SyncWhen's answer:
Anyone coordinating time across a group without wanting the overhead of a meeting platform: small teams planning weekly syncs, study groups and classmates, families organizing get-togethers, hobbyists scheduling club meets, and educators running office hours. Mobile-first design means participants can vote from a phone in seconds, which is where most group-chat invites get opened.
SyncWhen's answer:
SyncWhen started as a reaction to how bloated scheduling polls had become. Doodle used to take 30 seconds โ now it's account creation, cookie banners, upsell modals, and ads. The premise: strip it back. One URL, three voting options, real-time results, no friction for anyone. Built as an indie product, 12 locales shipped at launch to reach users who don't get served by US-centric tools.
SyncWhen's answer:
Rails 8, Vue 3 (Composition API), PostgreSQL, ActionCable for real-time updates, Puma, Propshaft, Solid Queue / Solid Cable, Tailwind CSS v4. Deployed on a self-managed VPS with nginx + Let's Encrypt.

Omniagent looks quite similar to OpenRouter (https://openrouter.ai/). - Source: Hacker News / 8 days ago
It's very easy to use other providers. See https://openrouter.ai/ which also let's you filter by where the provider is hosted and their data retention policy. - Source: Hacker News / about 2 months ago
If you want to try it yourself: grab OpenCode, point it at OpenRouter, select GLM 5.2, and give it a real task instead of a benchmark. The z.ai docs have the rest of the details. - Source: dev.to / about 2 months ago
Hosted, minimal ops. You want to be calling models in five minutes and you are fine paying a small fee for it. OpenRouter is the marketplace default โ 400+ models, ~5.5% on credits. Vercel AI Gateway and Cloudflare AI Gateway go further and charge 0% markup, billing you at provider list price while adding routing and caching on top. - Source: dev.to / 2 months ago
I use OpenRouter as the single door to a pile of models. Its BYOK (bring-your-own-key) feature has a trap. You add your own OpenAI key for a model, flip on "Always use for this provider," and read that as never spend OpenRouter credits. It doesn't mean that. - Source: dev.to / 2 months ago
