BxPlaywright vs Skyvern

BxPlaywright 53

The snapshot build of 23 October 2026 is the latest published package, so 30 on time, though it isn't a release (30). No tagged releases or dated changelog entries in the 90 days, only one version rebuilt (0 of 20). 39 pull requests merged by Luis Majano between 30 September and 23 October. Issue replies couldn't be read and bugs go to Jira (10 of 25). Not in the official MCP registry, and the ForgeBox package has no stable version (5 of 15). Playwright for Java 1.63.0, Dependabot for Gradle monthly and Actions quarterly, a daily test run and a format check (8 of 10). 30+0+10+5+8 = 53.

Skyvern 85

Version 1.0.55 on PyPI and npm on 1 October 2026, seven days before this check (30). Twelve weekly changelog entries since 13 July 2026, and PyPI releases 1.0.47, 1.0.48 and 1.0.55 in the same period (20). The repository had 200 commits between 16 September and 7 October and 48 open issues, several opened in the last fortnight. GitHub didn't show us the replies, and an issue of 8 September 2026 asks whether anyone watches the private advisory queue, so we scored this below full (14). Listed in the official MCP registry as io.github.Skyvern-AI/skyvern, active, but the entry is version 1.0.23 from 13 March 2026 and lists only the API-key header (13). CI runs pre-commit hooks, a migration check, pytest and pip smoke tests on Python 3.11 and 3.13, with a locked dependency file. We couldn't read whether the default branch passes (8).

BxPlaywright 60

Free, self-hosted, nothing to buy, so 20 + 20 + 20. The BoxLang runtime's paid plans aren't needed for this module. No payment protocol (0). 60 in all.

Skyvern 32

No x402, MPP or L402 in the docs, llms.txt or pricing page (0). Plan prices are public with credit allowances, Free 5,000 credits once, Hobby $29 for 30,000 a month, Pro $149 for 150,000, Enterprise custom. The price of extra credits isn't published, and the pages disagree on what a credit buys, one credit an action in the billing docs against about 170 or about 200 actions for 5,000 credits (12). The Free plan needs no card, per the pricing page (20). Signup is a browser flow, including skyvern signup from the CLI, so a person has to create the account (0). The open-source server is free to run under AGPL-3.0 with your own model keys, and we scored the hosted service because that is what the MCP and API docs point agents to.

BxPlaywright 66

Library reading. BoxLang is dynamically typed. The public API is listed in the docs' integrations page, help() and bxplaywright help --json describe it at run time, and the ten agent tools describe each argument in a sentence, with no published API reference (14 of 25). llms.txt with a Markdown copy of each of 18 docs pages (10). The AI page says when to use aiTools(), the registry or MCP, and when to turn registration off. Tool descriptions are one line each (13 of 20). Every agent-tool argument is a string, with no enums or limits; library options are checked, and InvalidOption lists the valid values (9 of 15). An errors page lists each error type with when it happens and the fix, eight runnable examples sit in the repository, and the docs have code on every page (13 of 15). Keep a Changelog and docs versioning on release, but no released version and no tags yet (7 of 15). 14+10+13+9+13+7 = 66.

Skyvern 88

OpenAPI 3.1.0 at /docs/api-reference/openapi.json with 94 operations on 71 paths and 261 schemas, and MCP tools with typed parameters (25). llms.txt, llms-full.txt and a Markdown twin of every docs page (10). The MCP server ships a routing table that says which tool to use for each kind of job, what each costs in model calls and what not to use it for, and tool docstrings repeat it. Many REST operations have one-line descriptions such as "Run a task" (16). Inputs are typed with enums and ranges, such as limit 1 to 500 on the audit export, but skyvern_workflow_create takes the whole definition as a JSON or YAML string and the spec marks x-api-key as optional on every operation (11). Code samples in Python, TypeScript and cURL and a full error-handling guide, while 422 is the only error documented on most operations, with 404 on 31 of 94 and 429 on two (11). /v1 path versioning with a written compatibility policy and a weekly dated changelog (15).

Read with the local-software lines and graded as a pre-release. Official package on ForgeBox with BoxLang 1.17.0 or later, Java 21 and the supported platforms stated, but the only version is 1.0.0-snapshot, rebuilt from the development branch on 23 October 2026, with no binary hash on the entry (14 of 20). tests.yml runs 24 test files on Ubuntu and Windows with JDK 21, real-browser tests on Linux and a test of the full distribution, on pull requests, pushes to development and daily. Whether runs pass wasn't read, since WebFetch refused GitHub (15 of 25). Issues weren't readable for the same reason, bugs go to Ortus's Jira, and the repository is a month old, so there's no record to read (5 of 25). Keep a Changelog with semantic versioning stated and a written public contract, but nothing has been released under it and the changelog reads only [Unreleased] (7 of 15). Ortus announced 1.0 as generally available on 13 October, but no 1.0.0 build or tag exists, so it isn't 1.0 for this line (0 of 15). 14+15+5+7+0 = 41.

Skyvern 57

Graded as a hosted service, Skyvern Cloud at api.skyvern.com. status.skyvern.com is a Statuspage site with three components (API, web application, async workers), 90-day uptime bars and an incident feed back to March 2025 (20). The feed has one incident in the 90 days to 8 October 2026, marked major by Skyvern, on 6 August, when an upstream model provider rejected requests and task and workflow runs failed at elevated rates from about 21:20 UTC to 22:30, roughly 70 minutes. A 29-minute run of 503s on 3 July falls just outside the window (10). The pricing page gives concurrent runs per plan (1, 10, 25, 100) and API responses carry ratelimit-policy: "submit-run";q=50;w=60, but we found no documented request limits (8). The OpenAPI document describes 503 with Retry-After on run submission and 429 on two recipe endpoints, and the SDKs retry network errors and 5xx with backoff. Idempotency-Key exists only on POST /v1/agents, so retried run submissions rely on the 503 saying no run was created (9). The pricing FAQ mentions custom SLAs for Enterprise and nothing is published (0). /v1 is declared stable (10).

BxPlaywright 43

Library reading, as puppeteer and playwright-mcp were. No credential to leak and nothing to scope, so the middle band (20 of 30). Nothing is restricted by default. browser_visit takes any URL with no allow-list, browser_screenshot writes to any path the model passes, and the tools are added to bx-ai's global registry unless registerAiTools is false, so an agent given every registered tool gets a browser. Over MCP it starts Microsoft's server, which limits file access to workspace roots, and Ortus's plugin starts it with --headless but without --isolated, with browser_run_code_unsafe and browser_evaluate in the default set. HTTPS errors are not ignored by default (6 of 20). Page snapshots and text go to the model unfenced, and the docs give no prompt-injection guidance (0 of 15). Screenshot, trace and video policies, show-trace, and interception points such as onPageCreate and onPlaywrightArtifact give the operator a record, all off by default (10 of 15). CONTRIBUTING.md asks for reports to security@ortussolutions.com and the Slack #security channel; SECURITY.md points there. No security.txt (410, per the boxlang-ai check of the same day), no bounty, no advisories. Node.js downloads are checked against the release's SHA-256 list (7 of 20). 20+6+0+10+7 = 43.

Skyvern 59

An organisation-wide API key in the x-api-key header, revocable and rotated from Settings, or OAuth 2.0 with PKCE, dynamic client registration and rotating single-use refresh tokens. The docs say plainly that OAuth scopes are identity claims and that there are no read-only, per-endpoint or per-resource credentials, so we scored plain revocable keys. No secret travels in a URL (20). MCP tool scopes are documented as a usability filter and not a permission boundary. Separate organisations are the only isolation, Human Interaction blocks are listed for Enterprise, and skyvern_act rejects prompts that contain passwords (6). Web pages are untrusted content. Stored credentials reach the browser directly and appear to the model as placeholders, the May 2026 changelog records sanitising of page content in prompt templates, and one tool description says page content is data, not instructions. We found no guidance page on prompt injection (8). GET /v1/audit-events/export returns organisation audit events for a default 90 days as JSON or CSV, and each run keeps a recording, screenshots, an action timeline and a HAR file (14). The site claims SOC 2 Type II and HIPAA on Enterprise, with a trust centre that didn't render for us. SECURITY.md routes reports to GitHub private advisories and its supported-versions table still says 0.1.x. No security.txt and no bug bounty found. The webhook page warns that its verifier examples before August 2026 accepted any signature of the right length (11).

Library reading, scored on what a tool-calling agent gets. Ten compact in-process tools for BoxLang AI, with nothing to load until a tool is used (25 for ten or fewer), less 5 because every action tool returns the whole page's AI snapshot. Through MCP an agent gets Playwright's 24 default tools (20 of 25). The agent tools have no depth, selector or size limit, and browser_text returns the whole page. snapshot( selector ) exists in the library but not in the tools (8 of 20). Errors come back to the agent as text in the form Error [type]: message Fix: detail, and the error types are documented (16 of 20). Assertions retry until they pass. The in-process tools carry no read-only or destructive hints, and bx-ai doesn't read them; over MCP the annotations are Microsoft's (8 of 20). Works with defaults (headless Chromium, 1280 by 720) and profiles, but in one language, BoxLang, with the MCP route for any other client (11 of 15). 20+8+16+8+11 = 63.

The full MCP surface is 114 tools by the docs' count (5). Scopes cut that to 29 (operate), 32 (lean), 54 (browser) or 60 (build) through a URL such as /mcp/x/lean or the X-Skyvern-Scope header, and page reads are size-capped and selector-scoped (9, so 14). List endpoints take page and page_size, with status, search_key, tag and date filters, and max_steps bounds a run (17). MCP results return codes such as SELECTOR_NOT_FOUND and SESSION_EXPIRED with a hint, runs report status, failure_reason and a caller-defined error_code_mapping, and the SDKs raise typed errors. HTTP error bodies are mostly unspecified (16). Every tool has readOnlyHint, destructiveHint and openWorldHint annotations, 117 registrations in the 1.0.55 source. Idempotency-Key covers agent creation only, not run submission (14). A task needs only a prompt, and official SDKs exist for Python and TypeScript (15).
