What are the best alternatives to Scale AI for robotics data in 2026?
Last updated: 2026-11-09 · Independent research from each company's official site. No hands-on testing.
Answer in brief
Scale AI's Physical AI Data Engine is the volume leader on our list. Scale says it ingests 1,000+ demonstration hours a day. But it is a sales-led, custom-quote program built for large labs. The strongest alternatives for robot-learning teams are Labelbox Terra (coverage-steered collection with evals), Encord (a platform you control, plus collection in its own facilities), Graviti (datasets you can license today from a public spec), Guardian AI (verified egocentric capture and remote teleop on your robots) and Robgence (two-week pilots and native LeRobot, RLDS and HDF5 delivery).
Top pick alternative: Labelbox Terra. It is the closest like-for-like engine. Seven synced rig types, one episode format from pre-training to evals, and 1 PB+ produced as of January 2026. Visit Labelbox →

The managed-engine rivals
Labelbox Terra: coverage you can see
Terra counts every episode against a target distribution across environments and tasks, then steers collection to the gaps. Rigs range from ego mono up to trio + instrumented gripper, plus teleop with joint states and actions. Labelbox recently announced a $100M+ Series E. Visit Labelbox → · Labelbox review
Encord: own the pipeline
Encord labels RGB, depth, LiDAR and force/torque in one interface, curates by embeddings, and records teleop and egocentric data in its own facilities. It says more than 300 AI teams use it. Visit Encord → · Encord review
The faster, narrower alternatives
Graviti: skip the collection wait
Graviti publishes specs for Ego-Exo Workplace Tasks (4,300+ hours, 4 synced views, available) and Egocentric Household Activities (10,000+ hours, 2,400+ contributors). Each contributor signs a written, revocable consent covering AI training, and licenses are perpetual. Graviti says it replies within one business day. Visit Graviti → · Graviti review
Guardian AI: proof plus remote operators
Clips are signed at capture and screened for synthetic or re-filmed footage. Guardian operators can also drive your robots remotely. Visit Guardian AI → · Guardian AI review
Firsthand: the richest human-video stack
Ten synchronized streams per episode on its instrumented rig, and a buyer-owned perpetual license. Visit Firsthand → · Firsthand review
Robgence, Tacit Robotics and Rimb: quick starts
Robgence advertises two-week pilots, a policy smoke test and compatibility with OpenVLA, pi0, Octo and ACT (its scale figures are self-reported). Visit Robgence → · Robgence review. Tacit Robotics covers egocentric, teleop and handheld UMI capture and handles recruiting, hardware, sites, QA and delivery. Visit Tacit Robotics → · Tacit Robotics review. Rimb annotates the egocentric or robot footage you already have into rights-cleared episodes. Visit Rimb → · Rimb review
When to stay with Scale
Stay with Scale if you need many embodiments at once, a certified vendor (SOC 2 Type II, ISO 27001), and data that has already gone through Scale's own policy fine-tuning and evaluation. Visit Scale AI → · Scale AI review
FAQ
What is the cheapest way to start instead of Scale?
Rimb offers five free annotated episodes. Graviti provides evaluation samples. Firsthand's sample pack is free to download.
Which alternative works on my own robots?
Guardian AI operates your robots remotely, and Encord supports custom hardware in its collection pipeline.
Is there an off-the-shelf alternative?
Yes. Graviti licenses catalog datasets with public specs.
