Correction, 2026-10-02: the summary listed Pika as "free with a ration"; its free plan includes 0 monthly credits, so you buy a pack before you can generate anything, and the summary now says so. It also called a small paid plan the cheapest watermark-free hosted route, which we had not compared across vendors; that line now gives 8frame's prices as prices. We removed claims we had not measured (self-hosting as "the best deal in the category", hardware that "never pays back" at low volume, prompt adherence predicting your cost "far better"), added the LTX-2.5 and Wan 2.2 model cards as sources with their licence terms and hardware figures, and noted that on 8frame Wan 2.2 needs a start image or a video.
Correction, 2026-10-01: the price table listed Kling v3 Standard as a text-to-video option. On 8frame, Kling v3 needs a start image; for a text prompt the Kling route is Kling 2.6 Pro, 95 credits for 5 seconds with audio, which the table now shows.
Correction, 2026-09-30: the first version generalised about free tiers (watermarks on most, 480p caps, three to five clips) without sources. It now uses what Runway and Pika state on their own pricing pages.
The hosted free tiers we checked ration you, and the ration is small. Runway's free plan is 125 credits, once, which its own pricing page shows as enough for about 10 seconds of Gen-4.5; Pika's free plan includes 0 monthly credits, so you buy packs. The route without a ration is self-hosting an open-weights model, which costs a GPU and your time instead of credits. The useful comparison is which restriction you can live with.
TL;DR
- Free with no watermark and no cap: self-hosted open weights (LTX-2.5, Wan 2.2), at the cost of a capable GPU; check the licence, since LTX-2.5 is free for commercial use only under $10M annual revenue
- Free with a ration: Runway, 125 one-time credits (about 10 seconds of Gen-4.5)
- A free plan with no credits: Pika, 0 monthly credits ("packs only"), so you buy a pack to generate
- Watermarks: Runway lists "No watermarks" among the features of its paid Standard plan; Pika's pricing page lists no watermark on its free plan, but also no commercial licence
- Paid and watermark-free on 8frame: Pruna p-video Draft at 4 credits for a 5-second clip at 720p; Wan 3.0 is 24 credits for a 5-second clip at 480p, about $0.24, if you want Wan
The three restrictions, and which to accept
Watermark. Fine for learning and personal use, fatal for anything client-facing or commercial. Check the plan page: a paid plan listing "no watermarks" as a feature tells you what free output carries.
Resolution cap. Some free tiers cap resolution or export quality. Acceptable for checking motion and composition, not for delivery.
Generation ration. A one-time or monthly credit allowance. Runway's 125 one-time credits are about two 5-second Gen-4.5 clips. Enough to evaluate a model, never enough to produce.
Pick by what you are doing. Learning to prompt: any of them. Producing a deliverable: none of them.
The self-hosted route
LTX-2.5 and Wan 2.2 publish weights, so running them on your own hardware costs electricity and setup rather than a subscription. LTX-2.5 is the newer of the two and generates synchronized audio; its community licence allows commercial use at no cost under $10M annual revenue, with a paid agreement above that. Wan 2.2 is Apache 2.0, the more permissive licence, and its open release includes text-to-video models (on 8frame, Wan 2.2 needs a start image or a video and does not run from text alone). See best open source AI video generator 2026 for the licence detail, which matters more than the download does.
The honest cost: Wan 2.2's 5B model card asks for a GPU with at least 24GB of VRAM, such as an RTX 4090, and quotes a 5-second 720p clip in under 9 minutes on a single consumer GPU. Add an inference stack and the hours to set it up. If you already own such a card, the extra cost is electricity and your time. If you do not, compare the card's price with what your clips would cost on a paid plan before you buy one.
What paid actually costs, for calibration
Worth knowing before you spend hours working around a free tier. On 8frame, plans start at $19 a month for 1,000 credits, a credit is $0.01 at pack rate, and output is watermark-free on every plan:
| Clip | Credits | Approx |
|---|---|---|
| Pruna p-video Draft, 5s at 720p | 4 | $0.04 |
| Wan 3.0, 5s at 480p | 24 | $0.24 |
| Wan 3.0 Prime, 5s at 480p | 46 | $0.46 |
| Veo 3.1 Lite, 8s silent | 33 | $0.33 |
| Veo 3.1 Lite, 8s with audio | 54 | $0.54 |
| Kling 2.6 Pro, 5s with audio | 95 | $0.95 |
Kling v3 on 8frame animates a start image, so it is not in this text-only list; from a still, Kling v3 Standard is 86 credits for 5 seconds with audio.
Twenty 5-second drafts on Wan 3.0 at 480p are 480 credits, $4.80; on Pruna p-video Draft, 80 credits, $0.80. Set that against the time you would spend working around a watermark or a ration. (p-video is new to 8frame: we quote its price, not its quality.)
How to evaluate on a free tier properly
A free ration buys only a few clips, so spend them deliberately. Use one prompt with four checkable clauses (camera move, light direction, specific action, framing) and check how many survive. That tells you about the model's prompt adherence: every clause a model drops is a retry you pay for later, so check it before you judge the model by whether the free clip looked nice.
Do not spend every free generation on a different prompt. Run the same prompt more than once to see how much the result changes between runs.
FAQ
Is there a free text-to-video generator with no watermark? Self-hosted open weights, yes. Hosted, the catch moves rather than disappears: Pika's free plan lists no watermark but includes no monthly credits and no commercial licence, and Runway lists "No watermarks" as a paid Standard feature.
What is the best free AI video generator? Depends which restriction you accept. Full comparison with the catch on each in best free AI video generators 2026.
Can I use free-tier output commercially? Check the specific tool's terms. Pika's free plan, for example, carries no commercial licence; on Pika it starts at the Creator plan.
