Ably is aimed at teams building realtime app features across several product types, with published support SLAs. Its listed starting price is $29, and the paid tiers warrant a close look at their 1K-MAU thresholds against your growth forecast. The alternatives below are not all like-for-like replacements: Daily and LiveKit lean toward voice and video, while Twilio and others cover broader communications workflows. Pick by workload and pricing model, not by entry price alone.
01Why people leave Ably
Paid tiers need a growth check
Ably’s paid tiers use 1K-MAU thresholds. Compare those limits with your growth forecast before treating the $29 starting price as your expected cost.
You may not need broad coverage
Ably covers several realtime product types. If your need is mainly voice, video or a specific messaging channel, a more focused option may fit better.
Your API needs may differ
If you need custom communications workflows or telecom services, compare providers built around those use cases rather than choosing on Ably’s realtime breadth alone.
02The alternatives, ranked by fit
- Realtime voice and video
DailyDailyDaily is a better fit if your Ably project is really about adding audio or video calls, or building realtime voice AI agents. Its listing also calls out an open-source agent framework and free minutes. That makes it worth comparing when those are your core requirements, rather than paying for broader realtime product coverage you do not need.
Trade-off: The included free minutes are not specified here; forecast usage before committing.
7.0/10from
Freefree plan - Voice and video agents
LiveKitLiveKitLiveKit suits teams building voice or video agents that want control over models and behavior. Its listing shows a free plan and a $50 starting price, with minute caps to account for. Consider it if that agent-focused toolkit matches your workload better than Ably’s broader realtime offering.
Trade-off: Session minutes, models and telephony affect cost; the included minute caps are not listed here.
7.6/10from
$50/mofree plan - Custom communications workflows
TwilioTwilioTwilio is worth comparing if your app needs custom communications workflows across several messaging channels. Its APIs are usage-based, and the listing shows a free plan with a $0.0001 starting figure. That pricing model may fit a channel-specific build better than Ably’s MAU-oriented paid tiers, but compare actual usage before switching.
Trade-off: Usage costs and messaging registration can add friction; the listed starting figure is not a full cost estimate.

$0.00/mofree plan - Voice, video and messaging
Vonage Communications APIsVonage Communications APIsVonage Communications APIs cover voice, video and messaging, making them a candidate if you need those communications features more than Ably’s broader realtime product mix. Its listed starting price is $13.99. Compare the API pricing against your specific use, since the available information does not establish a like-for-like cost.
Trade-off: API pricing and user sentiment are unverified in the published information.
5.5/10from
$13.99/mo - Enterprise voice and messaging
Bandwidth Communications APIsBandwidth Communications APIsBandwidth is aimed at enterprises building voice and messaging products, with U.S. SMS and RCS APIs and SIP trunking among its listed use cases. It may fit better if those telecom capabilities are central to your app. Pricing is listed as unavailable, so get usage-based costs before treating it as a budget alternative.
Trade-off: Pricing and public signals on service quality are limited.
6.0/10from
Custom - Multichannel customer conversations
GupshupGupshupGupshup fits teams focused on multichannel customer conversations, WhatsApp campaigns or AI in voice support. Its pay-as-you-go entry pricing may be relevant if your Ably use case is closer to customer communications than app infrastructure. The listed starting price is unavailable, so clarify the fees and limits before comparing total cost.
Trade-off: Limits are unclear, and layered fees may complicate cost estimates.
6.8/10from
Custom - Messaging and payments
CM.com Communications PlatformCM.com Communications PlatformCM.com is a candidate if you want messaging and payments together, or need to coordinate customer conversations across teams. Its listing also includes AI agents across channels. The starting price is $58, so compare that cost with the features and limits you actually need before moving from Ably.
Trade-off: Important plan limits are not specified in the available information.

Questions people ask
Which Ably alternative is cheapest?
The listed starting figures are not directly comparable: Daily shows $0 with a free plan, Twilio shows $0.0001 with a free plan, and LiveKit starts at $50 with a free plan. Those figures do not establish total cost. Check usage charges, included limits and the pricing basis before choosing.
Which Ably alternative is closest for voice and video?
Daily and LiveKit are the clearest fits in this list for audio or video calls. Daily also lists realtime voice AI agents and an open-source agent framework; LiveKit focuses on voice or video agents and model and behavior control. Neither description establishes a like-for-like replacement for every Ably use case.
Are these drop-in replacements for Ably?
The available information does not establish that any of these are drop-in replacements. Their listed use cases vary from voice and video agents to messaging and telecom APIs. Before switching, confirm that your chosen provider supports the specific product types and workflows your app depends on, then compare its pricing limits with your forecast.
