BoxLang AI vs Agent Development Kit (ADK)

BoxLang AI 71

Framework reading. 30 for what leaves the machine and credentials, 20 for approvals and sandboxing, 15 for prompt injection, 15 for audit and 20 for the security programme. No telemetry in the module's source, requests go only to configured providers, keys come from settings or environment variables, and request logging is off by default. 3.4.0 fixed a Gemini key leaking into logs through the request URL (27 of 30). Approval is enforced in code by HumanInTheLoopMiddleware with five policies, GuardrailMiddleware blocks tools by name and argument pattern, and stdio commands never use a shell. All of it is opt-in. allowedCommands allows any executable by default, FileSystemTools allows any path without allowedPaths, and the MCP server has no authentication unless configured (12 of 20). Unicode hygiene and fencing of ${context} are on by default, with opt-in input sanitiser, LLM judge and output guard. Streaming guards detect after the fact, which the changelog says (14 of 15). About 70 interception points, LoggingMiddleware, FlightRecorderMiddleware and MCP server statistics, with no OpenTelemetry export (11 of 15). CONTRIBUTING.md asks for reports to security@ortussolutions.com and the Slack #security channel. No security.txt (410), no bounty, and no published advisory found, while 3.6.0 lists a SQL injection fix in MySQL vector memory under Fixed (7 of 20). 71 in all.

Agent Development Kit (ADK) 92

We found no usage telemetry in the docs or the Python source, and capturing message content in traces is opt-in (30). Tool confirmation for human approval, extended to workflow tool nodes in 2.11.0 and to any workflow node through require_confirmation in 2.12.0, the docs say to always pass tool_filter to McpToolset, 2.12.0 limits the mutating /dev and agent builder endpoints of adk web to local clients by default, and sandboxed code execution is recommended for model-written code (20). Before-tool callbacks, an after_tool_callback that screens tool output since 2.12.0, plugins, a Model Armor plugin, an optional ToolCallIntegrityPlugin since 2.11.0, and a safety page that covers indirect prompt injection through tool results (15). OpenTelemetry traces with Cloud Trace and about 20 third-party integrations (15). SECURITY.md routes reports to Google's g.co/vulnz with a one-day triage target, per the 1 October check, not re-read on 1 November (the repository still has no SECURITY.md file and GitHub's security page answered 403). Google as CNA has published six 2026 CVEs with fixed versions, the newest on 23 and 28 October, but there are no repository advisories and no bounty is mentioned in the policy (12). Framework reading, so SOC 2 isn't scored.

BoxLang AI 71

Framework reading. A reference page for each built-in function with its arguments, and tool schemas generated from typed function arguments with required fields since 3.3.1. BoxLang is dynamically typed and no published API reference was found, though the repository builds DocBox API docs (15 of 25). llms.txt with about 150 entries and a Markdown copy of every page (10). The FAQ says when to use aiChat() or aiAgent() and the security guide says which guards to use when, though some FAQ links still say coming soon for pages that exist (14 of 20). Tool arguments are typed with required lists, and stdio options a server doesn't have throw InvalidArgument (11 of 15). About 100 example scripts in the repository and a gallery on ai.boxlang.io, but the production guide catches RateLimitException, TimeoutException and AuthenticationException, which the module's source never throws, and there is no exception reference (9 of 15). Keep a Changelog and a release-history page per version, but the 3.6.0 page still read unreleased on 1 November and two old versions appear twice in the changelog (12 of 15). 71 in all.

Agent Development Kit (ADK) 87

An API reference on adk.dev (25). llms.txt with about 250 entries and Markdown versions of each page (10). The docs explain the agent types and when to use workflow agents, but say little about when not to use ADK (15). Tools are typed functions, and McpToolset keeps the server's schemas (12). Examples throughout, but the MCP page has no error handling section and we found no exception reference (10). Dated changelog and release notes (15).

BoxLang AI 66

Read with the local-software lines. Official package on ForgeBox, installed with install-bx-module bx-ai or box install bx-ai, with BoxLang 1.14.0 or later in box.json and JDK 21 in CONTRIBUTING.md, but the 3.6 announcement says BoxLang 1.18 or later (18 of 20). tests.yml runs about 140 test classes against Ollama and the vector stores in Docker Compose, and against paid providers on development and releases, on pull requests and pushes to development. Whether runs pass wasn't read, since WebFetch refused github.com (15 of 25). Open issues and replies weren't read for the same reason. The changelog closes issues #182 to #259 in 3.3.1 to 3.4.0, and bugs also go to Ortus's Jira (10 of 25). Keep a Changelog with semantic versioning stated and Migration sections, but breaking changes ship in minor releases (8 of 15). 3.6.0, past 1.0 (15). 66 in all.

Agent Development Kit (ADK) 80

Official packages on PyPI (Requires-Python >=3.11 since 2.12.0, constraint files for 3.11 to 3.15) and npm (20). The continuous-integration workflow passes on main, per the 1 October check, not re-read on 1 November (25). 300 open issues and 261 open pull requests, per the 1 October check, not re-read on 1 November (12). The changelog calls out breaking changes, but they keep shipping in minor releases of a post-1.0 package (2.6.0 on 2026-07-29 and 2.7.0 on 2026-08-13), 2.12.0 on 2026-10-13 dropped Python 3.10 with no line in its changelog, and 2.8.0 reverted an A2A guard that had broken every tool confirmation. On 8 October the changelog relabelled the 2.11.0 dev UI config change a bug fix and the 2.9.0 resumption changes behaviour changes. 2.13.0 (22 October) marks one more breaking change, the telemetry schema default, in a minor release (8). 2.12.0, past 1.0 (15).

BoxLang AI 50

Self-hosted rule, scored on the paid option. No payment protocol (0). BoxLang runtime plans are public without a login, Starter $749 a year and BoxLang+ and BoxLang++ from $1,999 to $4,999 a server or node a year, plan pricing rather than per unit (10). The Apache-2.0 module installs with no card (20) and no account or sign-up (20). 50 in all.

Agent Development Kit (ADK) 60

No payment protocol (0). Scored on Agent Runtime, the hosted option, which publishes per-unit prices without a login ($0.085 a vCPU-hour, $0.009 a GiB-hour, 50 vCPU-hours and 100 GiB-hours free a month) (20). The Apache-2.0 package installs with no card (20) and no account, and runs local models (20).

BoxLang AI 83

3.6.0 on 2026-10-20 (30). Three releases in the 90 days to 1 November, 3.4.0 on 1 September, 3.5.0 on 11 September and 3.6.0 on 20 October (20). 79 commits on the development branch in those 90 days from Luis Majano, Doug Cain, Copilot and dependency bots, with pull requests up to #326 merged on 1 November. Issue reply times couldn't be read (10 of 25). The ForgeBox package is current at 3.6.0 (15). Dependabot for Gradle monthly and Actions quarterly, tests on pull requests and development, and a format check (8 of 10). 83 in all.

Agent Development Kit (ADK) 90

2.13.0 on 2026-10-23 (30). 15 Python releases in the 90 days from 3 August across the 1.x and 2.x lines, from 2.6.2 to 2.13.0, the newest 1.x being 1.39.1 on 2026-08-27 (20). 300 open issues and 261 open pull requests per the 1 October check, and we couldn't see reply times (15). Python is current, @google/adk is at 2.4.0 on npm, the Go module at v1.9.0 (tagged 15 October) and the Java artefact at 1.13.0 (21 October) (15). CI passes per the 1 October check, and 2.7.0 fixed zizmor findings in the workflows (10).

BoxLang AI 74

Framework reading, scored on what a tool-calling agent with MCP takes. An agent with an MCP server is one aiAgent() call with mcpServers, and toolFilter and prefix limit what each server adds. Skills can load lazily, but autoLoadSkills is on by default and injects every SKILL.md under /.agents/skills into every agent (20 of 25). MaxToolCallsMiddleware caps tool calls, window and summary memory bound history by messages or tokens, withMaxResponseBytes caps MCP answers and listTools( cursor ) pages tools (17 of 20). Named exceptions (ProviderError, UnsupportedCapability, InvalidArgument, MCPCommandRefused, BXAI.SecurityViolation) but no reference page, and the changelog says a timed-out call still surfaces as a JSON parse error (12 of 20). RetryMiddleware with exponential backoff, approval resumes that don't replay the model call or rerun executed tools, and a stdio client that never repeats an in-flight call. MCP tool annotations such as readOnlyHint aren't read (15 of 20). An agent needs a name and works with defaults, and a mock provider runs with no key, but it is one language (10 of 15). 74 in all.

Agent Development Kit (ADK) 80

An agent with one MCP server is about 15 lines with the built-in McpToolset, and tool_filter limits which tools load, with no dynamic filtering or deferred loading that we saw (20). RunConfig caps model calls per run, and the context compression page documents token-based and sliding-window compaction through EventsCompactionConfig, plus context caching (20). No exception reference or MCP error handling documented (5). Invocations are resumable, model calls take retry options, and 2.11.0 adds an abort_signal for graceful cancellation (20). An agent needs a name, a model and an instruction, in Python, TypeScript, Go, Java or Kotlin (15).
