Real-time / WebSocket Infrastructure
The clearest split is that Agora uses a freemium model and 100ms uses a subscription model. Agora is Real-time audio, video, and interactive live streaming SDK with global SD-RTN network infrastructure; 100ms is Real-time / WebSocket Infrastructure tool for developers. The data points Agora at chat applications and live collaboration features, and 100ms at chat applications and live collaboration features. Pricing: Agora is freemium, free tier; 100ms is subscription from $500 per month. Lock-in is low for Agora and low for 100ms, with DX at 5/5 vs 4/5 and transparency at 4/5 vs 3/5. On listed strengths, Agora emphasises chat applications and live collaboration features, and 100ms emphasises chat applications and live collaboration features. Both offer an enterprise tier for larger rollouts. Honest trade-off: neither fits static projects, so if that is your context, look elsewhere; otherwise pick on the pivotal factor above and the DX score that matters most to your team.
Quick take
Agora is for chat applications; 100ms is for chat applications; decide based on which pricing model fits your budget.

Entry pricing is listed as unknown for Agora and $500 per month for 100ms. Both offer a free tier for getting started. Total cost at scale depends on usage and plan details that are not in this dataset, so confirm with each vendor.
Agora is tagged with low lock-in (proprietary sd-rtn network and signaling; switching requires rewrite). 100ms is tagged with low lock-in (proprietary real-time sdk with custom session model; migration requires rewrite). Both sides are low lock-in, so a migration is feasible but still needs planning around data export and SDK rewrites.
The dataset rates Agora at 5/5 for developer experience and 100ms at 4/5, so Agora scores higher. That score reflects overall polish rather than any single integration, so trial both against your stack before committing.
Yes for teams whose workload matches chat applications, since both list the same fit. 100ms is flagged as not for static projects, so confirm your context does not fall there.
