| # MiniWeb |
|
|
| MiniWeb is a benchmark for web agents that measures skills, not only tasks: 65 locally hosted websites, 37 interaction |
| primitives (searching, filtering, filling forms, dragging, uploading, ...), and 369 human-written tasks whose every step |
| is labeled with the primitive it exercises and checked by a verifier. MiniWebGen generates practice data for each |
| primitive on the training sites, and MiniWebAgent is trained on it. The code that serves the sites, runs the |
| evaluations and reproduces the paper is in the MiniWeb repository. |
|
|
| ## Tables |
|
|
| | Config | Rows | One row per | |
| |---|---|---| |
| | `tasks` | 369 (train 304, test 62, excluded 3) | human task: instruction, primitives, the task and verifier as evaluated, the annotator's originals, provenance, the demonstration's server and input logs | |
| | `demonstrations` | 17.4K | recorded event of a human demonstration (action or observation), with the page's HTML, accessibility tree and screenshot where recorded; `screenshot` rows at the end hold captures no event points to | |
| | `miniwebgen_trajectories` | 3,128 | MiniWebGen trajectory of one primitive on a training site, with its backend and judge verdicts | |
| | `miniwebgen_steps` | 17.1K | step of a MiniWebGen trajectory, with its screenshot and the targeted page element; `phase` is `history` for the steps of the primitive a chained trajectory starts with | |
| | `training_steps` | 31K | step of MiniWebAgent's training data in the agent harness's format: prompt messages, target action, screenshot; `is_target` and `validation` mark the 27.6K steps it is fit on | |
| | `task_centric_tasks` | 7,280 | task proposed for the task-centric comparison, with its judged outcome | |
| | `task_centric_steps` | 27.6K | step of the task-centric training data, in the same format as `training_steps` | |
| | `single_primitive_test_tasks` | 115 | generated single-primitive task of a held-out site (evaluation only) | |
| | `sites` | 65 | website: domain, train or held-out split, data source and its license | |
| | `primitives` | 53 | primitive (46 initial, 37 kept) or reasoning operation | |
| | `guides` | 46 | MiniWebGen's guide for a primitive | |
|
|
| Nested fields (verifiers, logs, prompt messages, actions) are JSON strings. `test` is the 13 held-out sites: no |
| training data comes from them. |
|
|
| ```python |
| from datasets import load_dataset |
| |
| tasks = load_dataset("sparklabuofu/MiniWeb", "tasks", split="test") |
| steps = load_dataset("sparklabuofu/MiniWeb", "training_steps", split="train", streaming=True) |
| ``` |
|
|
| ## The websites |
|
|
| `site_db/` holds everything the sites need to run offline: one Parquet file per table of the 65 sites |
| (`site_db/tables/<site>/`), the schema (`schema.json`), the rows each full-text index holds (`fts_rowids/`), the sites' |
| own images (`static.parquet`: generated product shots, post images, book covers, avatars), and a copy of the external |
| media the pages show (`media/`: images that site data links to on other hosts, such as product and phone photos, |
| wikiHow step images and images inside posts, plus the map's basemap tiles; `media_manifest.parquet` lists every linked |
| URL and whether it could still be fetched). `scripts/restore_site_db.py` in the code repository downloads it, rebuilds |
| the SQLite database the sites run on, with search behaving exactly as when the tasks were recorded, and unpacks the |
| media, which the server then serves in place of the original links. Session state from our evaluations is not |
| included. |
|
|
| ## Updates |
|
|
| - 2026-10-19: a task audit removed 7 tasks (369 remain, 62 of them in `test`), corrected the verifiers of 51 |
| tasks and the definitions of 48, and re-recorded 37 demonstrations; the `sites` table has corrected source and |
| license notes for 4 sites. Earlier versions stay in this repository's history. |
|
|
| ## Privacy |
|
|
| Annotators appear only as the pseudonyms A1 to A6. The sites' people are synthetic, apart from the public sources |
| listed in `sites` (for example the Enron email corpus and the WebArena Reddit and GitLab environments). |
|
|
| ## License |
|
|
| - Data created for MiniWeb (tasks, verifiers, demonstrations, MiniWebGen and task-centric data, the synthetic data of |
| 44 sites): CC BY 4.0. |
| - Data of the 21 sites seeded from public sources: the license of each source, listed in the `sites` table. Some are |
| share-alike (CC BY-SA, ODbL) and some restrict use (wikiHow: CC BY-NC-SA; USA Real Estate: educational use), so |
| the site database as a whole is for non-commercial research. |
| - Screenshots and page snapshots show site content and carry the license of that content. |
| - `site_db/media/` archives third-party images that site data links to (for example product photos from WebShop's |
| data and phone photos from GSMArena), as WebShop and WebArena use them, so the benchmark stays reproducible; their |
| rights remain with their owners. |
