HeyGen vs Synthesia vs Runway (2026)

Three completely different tools that all make AI video โ€” but for different jobs. HeyGen is for avatar presenter videos. Synthesia is for enterprise training at scale. Runway is for generative cinematic footage. New: Runway retired its "Unlimited" plan for new subscribers (May 2026) โ€” replaced by "Max" ($76/mo annual, 9,500 credits, no more unlimited Explore Mode). Gen-4.5's credit cost is also confirmed higher than previously stated: 25 credits/second, not 12.

โš ๏ธ Major update โ€” Runway retired "Unlimited"

Explore Mode is gone for new subscribers

Runway retired its "Unlimited" plan for new subscribers as of May 29, 2026, replacing it with a "Max" plan. This isn't just a rename: the old Unlimited plan ($76/mo annual) provided 2,250 credits plus "Explore Mode" โ€” unlimited generations at a slower, relaxed processing rate. The new Max plan (same $76/mo annual price) provides 9,500 credits/month instead, with credits rolling over up to one month โ€” but Explore Mode has been discontinued entirely. There is no longer any true unlimited-generation option at any Runway tier. Multiple independent trackers note the old Unlimited was actually poor value (identical 2,250 credits to the $28/mo Pro plan, just at a much higher price with a throttled "unlimited" bonus) โ€” Max is regarded as a genuine improvement in raw credits, but buyers expecting "unlimited" should know that framing no longer applies. Existing Unlimited subscribers are grandfathered on their old plan. Separately corrected: Gen-4.5's credit cost is confirmed at 25 credits/second, not 12 as previously stated โ€” meaning actual generation capacity per plan is roughly half what earlier math suggested.

All prices are annual billing rates (USD/mo). HeyGen Business = $149 first seat + $20 each additional (shown as single-seat estimate). Runway Max (formerly Unlimited) now provides 9,500 credits/mo instead of Explore Mode. Gen-4.5 costs 25 credits/second on Runway. Synthesia and HeyGen Creator/Pro plans are individual, not per-seat.

๐Ÿ“Œ What Runway's credit math actually means now: on the Standard plan (625 credits/month), Gen-4.5 at 25 credits/second gives you just 25 seconds of flagship-model video per month โ€” roughly 2-5 short clips depending on length. Pro's 2,250 credits stretch to 90 seconds. The new Max plan's 9,500 credits give 380 seconds (about 6.3 minutes) of Gen-4.5 output โ€” a real, calculable ceiling now, rather than the old "unlimited at a slower rate" framing. These three tools are not really competitors โ€” they serve different jobs. HeyGen and Synthesia both use AI avatars for presenter-led videos, while Runway generates original cinematic footage from prompts. A content team might realistically use HeyGen for avatar videos AND Runway for AI-generated B-roll in the same project.

โš ๏ธ Hidden costs & gotchas

What vendors won't lead with

๐Ÿšซ Runway โ€” "unlimited" no longer exists at any tier

Explore Mode, the old Unlimited plan's unlimited relaxed-rate generation, was discontinued for new subscribers as of May 29, 2026. The replacement Max plan gives you a much larger but still finite 9,500 credits/month. If genuinely unlimited generation was your reason for choosing Runway, that option is gone for new signups.

๐Ÿ”ข Runway โ€” Gen-4.5 costs more credits than often stated

Confirmed at 25 credits/second across multiple detailed 2026 sources โ€” not 12/sec as some older comparisons (including a prior version of this page) stated. This roughly halves the real generation capacity per plan compared to that older math. Recalculate your expected output before committing to a tier.

๐ŸŽญ HeyGen โ€” Team plan deprecated January 2026

HeyGen's old Team plan is gone. The replacement Business plan starts at $149/month for the first seat plus $20/month per additional seat. Existing Team plan users who maintain continuous payments keep old terms โ€” but new customers cannot access the old pricing.

๐Ÿ’ณ HeyGen โ€” Premium Credits are a separate cost

The Creator/Pro/Business subscription gives you a base Premium Credits allowance. Advanced features (Avatar IV, lipsync translation, video generation via integrations) consume Premium Credits beyond the subscription price.

โฑ๏ธ Synthesia โ€” video minutes run out fast on Starter

The Starter plan includes 10 video minutes per month. A typical 5-minute training video consumes half your monthly allowance. Teams producing regular content quickly need the Creator plan (360 minutes/year) or Enterprise.

๐Ÿ’ฐ Synthesia โ€” custom avatar is a $1,000/year add-on

Creating a custom personal AI avatar is not included in Starter or Creator plans โ€” it's a $1,000/year paid add-on available only to annual plan subscribers.

โ“ Frequently asked questions

Quick answers

HeyGen is best for AI avatar video โ€” turning scripts into presenter-led videos without a camera or studio. It supports 175+ languages with natural lip-sync dubbing. The Creator plan at $24/month annual allows unlimited video generation. Note: HeyGen's Team plan was deprecated in January 2026 and replaced by the Business plan starting at $149/month for the first seat.

Runway retired the Unlimited plan for new subscribers as of May 29, 2026, replacing it with a Max plan at the same $76/month annual price. Max provides 9,500 credits/month (rolling over up to one month) instead of the old plan's 2,250 credits plus "Explore Mode" unlimited relaxed-rate generation. Explore Mode has been discontinued for new subscribers โ€” there is no true unlimited-generation tier at Runway anymore. Existing Unlimited subscribers are grandfathered on their previous terms.

Runway Standard costs $12/month billed annually ($144/year) with 625 credits/month for up to 5 users. Pro costs $28/month annual with 2,250 credits/month for up to 10 users. Max (replacing the old Unlimited plan) costs $76/month annual with 9,500 credits/month. Gen-4.5 costs 25 credits per second of generated video โ€” meaning Standard's 625 credits buy about 25 seconds of Gen-4.5 output per month.

Yes. Synthesia's free plan provides 10 video minutes per month, 9 stock avatars, and 160+ language support โ€” the most practically useful free plan in this comparison. HeyGen's free plan allows 3 videos per month (watermarked), and Runway's free plan provides 125 one-time credits with no monthly refresh.

No โ€” they serve fundamentally different use cases. HeyGen and Synthesia create avatar presenter videos from scripts. Runway generates original cinematic footage from text and image prompts. A content team might use HeyGen for avatar videos AND Runway for AI-generated B-roll in the same project.

HeyGen's Team plan was deprecated in January 2026 and is no longer available for new subscriptions. Existing subscribers who maintain continuous payments can keep their old terms. The replacement is the Business plan, starting at $149/month for the first seat plus $20/month per additional seat.

Ready to try these AI video tools?

All three offer free plans or trials. Synthesia's 10 min/month free plan is the most useful for evaluation.
