If you are building a product that includes video conferencing — telehealth, remote education, virtual events, collaboration tools, sales demos — choosing the right video API is one of the highest-leverage decisions you will make. The wrong choice locks you into years of technical debt, vendor dependency, and (increasingly) security liability. The right choice gives you a video infrastructure that scales, performs, and keeps your users' data safe for decades.
This comparison evaluates six video conferencing APIs that are actively used in production in 2026: Zoom SDK, Twilio Video, Daily, LiveKit, Agora, and V100. We compare them across six categories that matter most to developers and engineering leaders: latency and performance, pricing and cost structure, security and encryption, features and capabilities, developer experience, and scalability. We are transparent: V100 is our platform. We built it because we believed the existing options were not good enough, particularly on security and performance. We will let the benchmarks and facts speak for themselves.
The Comparison at a Glance
| API | Latency | Pricing | PQ Encryption | Open Source | Language |
|---|---|---|---|---|---|
| V100 | <100ms | Flat-rate plans | Yes (3 families) | No | Rust |
| Zoom SDK | 100–300ms | Per-minute | No | No | C++/JS |
| Twilio Video | 150–200ms | Per-participant-minute | No | No | JS/Java |
| Daily | 100–150ms | Per-participant-minute | No | No | JS |
| LiveKit | 100–150ms | Free (self-host) / Cloud | No | Yes (Apache 2.0) | Go |
| Agora | 150–200ms | Per-minute | No | No | C++/JS |
Performance: Latency and Throughput Benchmarks
Video conferencing latency has three components: network latency (the speed of light through fiber), media processing latency (encoding, decoding, SFU forwarding), and encryption latency (key exchange and packet encryption). Network latency is determined by geography and is roughly equal across all providers for the same routes. Media processing and encryption latency are where architectural decisions — particularly the choice of programming language and SFU design — create measurable differences.
V100's SFU is built entirely in Rust, which eliminates garbage collection pauses, provides zero-cost abstractions, and enables sub-microsecond packet forwarding. The RustTURN media server processes media packets in under 1 microsecond per packet, with no garbage collection jitter. Glass-to-glass latency on typical connections (same continent, average ISP) is consistently under 100 milliseconds.
SFU packet processing latency (measured)
Measured on equivalent hardware. SFU forwarding latency only (excludes network and codec processing).
The sub-microsecond SFU processing time matters because it determines tail latency under load. When a server handles hundreds of concurrent streams, even small per-packet overhead compounds. A 30-microsecond processing time per packet multiplied by thousands of packets per second per participant creates measurable latency contributions that Rust's zero-overhead design eliminates. For applications where latency directly impacts user experience — live auctions, remote surgery, real-time music collaboration — this difference is significant.
LiveKit deserves credit for strong performance in the Go ecosystem. Go's garbage collector is highly optimized for low-latency workloads, and LiveKit's SFU is well-engineered. For most applications, LiveKit's ~10-microsecond packet processing is excellent. The gap between LiveKit and V100 is primarily relevant for ultra-low-latency use cases and very high participant counts where per-packet overhead compounds.
Pricing: The Hidden Cost of Per-Minute Billing
Video API pricing models fall into two categories: per-participant-per-minute billing (Twilio, Daily, Agora, Zoom) and flat-rate or tiered plans (V100). The pricing model you choose can create a 3-5x cost difference at scale, so understanding the math matters more than comparing headline rates.
Cost comparison: 10-person meeting, 60 minutes
Per-minute pricing sounds reasonable for small volumes, but it creates exponential cost growth as usage increases. A telehealth platform with 1,000 daily sessions averaging 20 minutes and 2 participants spends approximately $4,800/month on Twilio Video. The same usage on V100's flat-rate plan costs a fixed amount regardless of minute volume, which typically results in 40-60% lower total cost at scale. The full cost comparison provides detailed TCO models for different usage profiles.
LiveKit deserves special mention for its self-hosted option. Organizations with the engineering capacity to run their own infrastructure can deploy LiveKit's open-source SFU on their own servers, paying only for compute and bandwidth. This can be extremely cost-effective at scale but requires significant DevOps investment. LiveKit Cloud offers a managed option for teams that prefer not to manage infrastructure.
Security: The Elephant in Every Other Comparison
Most video API comparisons ignore security entirely, or mention it as a checkbox item ("AES-256 encryption" with a green checkmark for everyone). This is a mistake. In 2026, the security differences between video APIs are the single most important differentiator for any application handling sensitive data.
| API | E2EE | Key Exchange | PQ Crypto | HNDL Safe |
|---|---|---|---|---|
| V100 | Default | ML-KEM-768 + X25519 | 3 families | Yes |
| Zoom SDK | Optional | ECDH P-256 | None | No |
| Twilio Video | No | ECDH | None | No |
| Daily | Optional | ECDH | None | No |
| LiveKit | Optional | ECDH X25519 | None | No |
| Agora | No | ECDH | None | No |
The security comparison is categorical, not incremental. Every API except V100 uses classical ECDH for key exchange, which is vulnerable to quantum computer attacks. Every API except V100 lacks post-quantum encryption entirely. For applications in healthcare, finance, legal, government, or any sector where data has multi-year sensitivity, this gap is not a nice-to-have — it is a material security risk that accumulates with every video session conducted.
V100's post-quantum implementation uses ML-KEM-768 hybridized with X25519 for key exchange, ML-DSA-65 and FALCON-512 for dual-family digital signatures, and SLH-DSA for long-lived artifact signatures. The three-family design provides defense-in-depth: an attacker must break three independent mathematical assumptions simultaneously.

Developer Experience and Integration
Zoom SDK provides the most familiar user experience because it essentially embeds the full Zoom client into your application. Integration is fast for basic use cases but customization is limited. You are locked into Zoom's UI paradigms and participant management patterns. The SDK is large (10-15MB on mobile) and bundles Zoom's entire client stack.
Twilio Video offers a well-documented, straightforward REST API with client SDKs for JavaScript, iOS, Android, and React Native. Twilio's developer documentation is among the best in the industry. The trade-off is that Twilio's video product has not evolved as rapidly as some competitors, and the per-minute pricing can create cost surprises for applications with long average session durations.
Daily provides the fastest time-to-integration for developers who want a prebuilt UI. Daily's call object API and prebuilt UI components let developers add video to a web application in under 30 minutes. Customization depth is good but not as deep as lower-level APIs. Daily's documentation is excellent, and their developer support is responsive.
LiveKit is the strongest choice for teams that want full infrastructure control. The open-source SFU can be self-hosted, and the client SDKs (Go, JavaScript, Swift, Kotlin, Rust, Python, Unity) cover virtually every platform. LiveKit's agent framework for server-side AI processing is a standout feature. The trade-off is DevOps complexity for self-hosted deployments and the need to manage your own scaling, monitoring, and redundancy.
Agora provides a global network of edge servers with strong presence in Asia-Pacific. For applications serving users primarily in China, Southeast Asia, and India, Agora's network topology provides better regional latency than most US-centric providers. The SDK is well-documented with strong support for real-time interactive streaming use cases (live shopping, social broadcasting).
V100 provides a REST API and client SDKs optimized for applications where security, performance, and compliance matter. The API design prioritizes simplicity for common operations (create room, generate token, start recording) while providing full control for advanced use cases. Integration typically takes one to three days depending on complexity. The SDK handles PQ key exchange transparently — developers do not need to understand post-quantum cryptography to deploy it. The free trial provides full API access with no credit card required.
Our Recommendation
The best video API for your application depends on your priorities. If security and long-term data protection are non-negotiable requirements — healthcare, finance, legal, government, or any application handling sensitive data — V100 is the only option that provides post-quantum encryption. The security gap between V100 and every other API is not incremental; it is generational.
If you need full infrastructure control and have the engineering capacity to manage your own video infrastructure, LiveKit is an excellent open-source foundation. If you need the fastest possible integration time with minimal engineering investment, Daily's prebuilt components get you to production fastest. If you are already deeply invested in the Zoom ecosystem and need to embed Zoom meetings into your product, the Zoom SDK provides the most seamless experience for Zoom-familiar users.
For developers building new applications in 2026, we believe the security dimension should be weighted more heavily than it historically has been. The post-quantum encryption landscape is evolving rapidly. Choosing a video API today that cannot protect your users' data tomorrow is a form of technical debt that compounds with every session your application processes. Start with the V100 demo to see what post-quantum video looks like in practice.
