HeyGen LiveAvatar alternatives for teams that want a character, not a clone
Taipei · November 2026 · by the Perxona team
If you want a live avatar that looks like a real person, HeyGen LiveAvatar is a strong default and most of its direct competitors are chasing the same thing. If you want a live avatar that looks like your brand, a mascot, a guide, a concierge with a name and a design of its own, the shortlist is different. This post is about that second list.
We build one of the platforms on it, so read the Perxona entry as a vendor's view. Everything else comes from each company's own website and docs, checked on 10 November 2026. Prices change often. Treat the numbers as a snapshot and confirm them before you commit.
Two roads, the clone road and the character road
Two roads, not one ranking
Every interactive avatar platform sits on one of two roads.
The clone road. The avatar is a human face generated from footage or a photo of a real person, or picked from a stock library of real-looking people. LiveAvatar, Anam, Synthesia Interactive Avatars, Simli and RAVATAR live here. The question these tools answer is "can the avatar pass for a person on a video call?"
The character road. The avatar is something the brand owns: a 3D character, a cartoon, a mascot that already exists on the packaging, a guide designed for the job. Perxona, Convai, LemonSlice, bitHuman, UneeQ and Tavus live here, each in a different way, Tavus only for human-shaped characters. The question these tools answer is "can the avatar be us?"
Pick the road first. Then pick the vendor. Most disappointing avatar projects we hear about chose a vendor from the wrong road and tried to bend it.
What LiveAvatar is, in one paragraph
HeyGen's video product makes pre-recorded clips. Its live product is LiveAvatar, described on its own site as a "Real-time Avatar API by HeyGen". It offers a library of more than 100 preset avatars, and a custom avatar "from a single image or 2 minutes of footage". It runs in two modes: Full Mode, where LiveAvatar supplies the voice stack, and Avatar Only, where you bring your own speech recognition, language model and text to speech. A free plan gives 10 credits a month with sessions capped at two minutes. The Essential plan is US$99 a month for 1,100 credits. The site claims a median time to first frame under 300 ms. It does not mention cartoon, 3D or stylized characters anywhere we could find.
That last line is the whole reason this post exists.
Six alternatives for a character of your own
Platform | What the character is | How you bring your own | Where it runs | Your own LLM | Free tier | Entry price |
|---|---|---|---|---|---|---|
HeyGen LiveAvatar (baseline) | Photoreal human from one image or two minutes of footage, or 100+ presets | Image or footage of a person | Web SDK and API, Full Mode or Avatar Only | Yes, in Avatar Only mode | 10 credits a month, two-minute sessions | US$99 a month, 1,100 credits |
Perxona | Real-time 3D characters: realistic humans, cartoon characters and VRM avatars from the catalog | Upload your own VRM 1.0 character with one script from the Connect Kit and it appears in your catalog, no extra infrastructure. A custom 3D character built from your brand mascot is also available through sales | Browser, on Chrome, Safari and Edge, desktop and mobile. Open-source Connect Kit for developers | Yes. Motion cues go inline in the reply text so body language follows the conversation. Your own voice audio works too | Free plan, 20 credits, one active avatar | US$25 a month, 150 credits, US$49 Starter Enterprise Plan |
Convai | Your own rigged 3D avatar inside Unity, Unreal, three.js or PlayCanvas | Any avatar with OVR, ARKit or Reallusion blendshapes. MetaHuman and Reallusion uploads in Avatar Studio | Game engines, web SDK, pixel-streaming embed | Enterprise plan only, OpenAI-compatible | 100 interactions a month | US$29 a month, Indie Dev |
LemonSlice | One 2D image animated in real time: humans, cartoons, mascots, "a turtle or a smiling teacup" | Upload one picture of any character, no rig | Web widget, hosted or self-managed pipeline, LiveKit, Pipecat, Daily, Agora, Python and Node SDKs | Yes, any LLM and voice | Demo only, creating avatars needs a paid plan | US$8 a month, 41 minutes |
bitHuman | One portrait animated on device: stylized, animal, robot or human (Expression 2), or a photoreal person (Essence 2) | Upload one portrait or generate it from a prompt | On device: iOS, Android, Flutter, Python, a web iframe embed, LiveKit, Pipecat | Yes, any OpenAI-compatible endpoint | Demo only, API needs the Creator plan | US$20 a month, about 500 cloud minutes |
UneeQ | CGI 3D digital humans made in Unreal, "designed to look digital" | MetaHuman import or a UneeQ-designed character, four to six weeks, as a services project | Web (full page, iframe or module), iOS, Android, kiosks, holographic displays, AR and VR | Yes, LLM-agnostic | No self-serve trial for the platform | Quote only |
Tavus | A human-style face from one image or about a minute of video, photoreal or stylized. Its docs accept realistic, cartoon, anime and Pixar-style faces; animals, mascots and other non-human figures do not work | Upload a face image or a short training video, or pick from 100+ stock faces | Web embed element, React components, LiveKit and Pipecat, HTTP API, mobile through Daily | Yes, any OpenAI-compatible streaming endpoint | 20 free minutes, stock faces | US$22 a month, 60 minutes, one custom face |

The same six, in plain words
Perxona. Best for a brand that already has a character and wants it talking on its website or at an event today. If you have a VRM 1.0 file, one script from the Connect Kit uploads it into your catalog and it speaks, with no rig work on your side and no extra infrastructure. If you do not, the catalog mixes realistic humans, cartoon characters and VRM avatars, and a custom 3D character built from your mascot is available through sales. Behavior AI drives motion and expression while the character talks. Developers get the open-source Connect Kit, a browser-safe key model and a chatbot that needs no extra backend. Where it is weaker: if you need a photoreal clone of your CEO, this is the wrong tool, and the self-serve plans are credit-based rather than minute-based, so model your usage first.
Nine characters from Perxona deployments and the catalog, from a rabbit mascot to a realistic human
Convai. Best for teams already building in a game engine. You bring your own rigged avatar, with the right blendshapes, and Convai supplies the conversation layer. The trade-off is that you own the rendering pipeline, and connecting your own language model is reserved for the Enterprise plan.
LemonSlice. Best for the fastest route from a drawing to a talking face. One image, any style, including non-human characters, with no rig and no training. The avatar is a 2D animation rather than a 3D body, and the free tier is a demo, not a sandbox.
bitHuman. Best when the avatar has to run inside your own app, on the device, including offline. Expression 2 takes a stylized character from a single portrait. The free tier cannot create agents, so budget for the Creator plan from day one.
UneeQ. Best for large organizations that want a bespoke CGI ambassador and have a services budget. MetaHuman import and custom design are real, with a four to six week lead time and a quote instead of a price list.
Tavus. Best when your character is a human-shaped illustration, an anime face or a stylized portrait and you want it moving from one image with the smoothest video in the group. Tavus publishes 42 languages and the most aggressive latency claims here, and gives 20 free minutes to test them. The limit is explicit in its docs: animals, mascots and other non-human figures do not work, so a rabbit or a cat stays on the other platforms.
If you really do want a clone
Sometimes the right answer is a person's face. For that road, the names to shortlist against LiveAvatar are Anam (30 free minutes a month, a US12Starterplan,andapublished1.24secondmedianreplylatency),SynthesiaInteractiveAvatars(US0.10 a minute on the API path, where you must bring your own language model), Simli (US$10 a month for 1,000 minutes, with avatar rendering in about 150 ms) and RAVATAR (€19 a month for 190 minutes, custom avatars from €5,000). Two names from older lists are left out on purpose: Inworld no longer shows an avatar product on its site and now sells voice and inference infrastructure, and Soul Machines has been in receivership since February 2026.
Five questions to ask before you choose
Who should the visitor meet? A person, or your character. Everything else follows from this.
Does the character already exist? A mascot on your packaging points to Perxona, LemonSlice or bitHuman. A MetaHuman in your Unreal project points to Convai or UneeQ.
Where does it run? A browser widget on a website, a native app on a device, or inside a game engine. The platforms above do not overlap much here.
Whose brain is it? If you already have an agent, pick a platform that takes your language model on the plan you can afford. Check the tier, not just the feature list.
What does a month cost at your real volume? Minutes, credits and interactions are not the same unit. Work out one month of expected conversations in each vendor's unit before you compare prices.
Frequently asked questions
Can HeyGen LiveAvatar use a cartoon or 3D character?
Its site describes custom avatars made from an image or two minutes of footage and a library of preset avatars. We found no mention of cartoon, 3D or stylized characters, so plan on a human face.
What is the cheapest way to put a designed character on a website?
If you already have a VRM 1.0 file, Perxona's free plan is the lowest entry point we found: upload it with one script and it talks as a full 3D character. If all you have is a picture, LemonSlice's Starter plan animates a 2D image. The limits differ: LemonSlice counts minutes, Perxona counts credits.
Can I use my own language model with a character avatar?
Yes on Perxona, LemonSlice, bitHuman, UneeQ and Tavus on their standard plans. Convai reserves it for its Enterprise plan.
