Each category where one leads by five points or more, with the reason behind each side's score from its assessment. The numbers are in the table below; this is what they stand for.

Maintenance & community Docker Agent +62

Docker Agent 96

v1.154.0 published on 2026-10-28 (30). 36 tagged releases in the 90 days from 3 August to 1 November, v1.120.0 to v1.154.0 (20). 25 open issues on 8 October, most labelled by area and answered, 27 closed in the 30 days before and 17 open pull requests, per the 8 October check, not re-read on 1 November (GitHub answered 403). We didn't measure reply times (21). The Homebrew formula was at 1.154.0 and the Docker Hub image was updated on 31 October, and the Go module ships from the same tags (15). Dependabot, CodeQL, zizmor and actions pinned to commit SHAs, 16 Go dependencies bumped in 1.153.0, with CI passing on main per the 8 October check (10).

smolagents 34

v1.26.0 on 29 May 2026, 161 days before this check (10). No release in the 90 days to 6 November (0). 416 open issues and 1,045 open issues and pull requests on 6 November, with 144 issues opened in the 90 days to 3 November. Of the 50 newest, 26 had a comment and 1 was closed. Two 2026 CVE records say the vendor didn't respond to the reporter, and seven commits reached main from 8 August to 6 November (6). Python only, and the package is the current one (10). CI with actions pinned to commit SHAs and Dependabot for actions (8). 10+0+6+10+8 = 34.

Reliability Docker Agent +24

Docker Agent 88

Read with the local-software lines, because the owner runs it. Binaries for macOS, Linux and Windows on amd64 and arm64 on every GitHub release, a Homebrew formula at 1.154.0 on 1 November, a Docker Hub image updated on 31 October, and Docker Desktop 4.63 and later bundle it. Go 1.27 is the stated minimum for source builds (20). The ci workflow runs on every push to main with about 1,350 test files and an e2e directory. Nine of the last ten push runs passed on 8 October, per the 8 October check, not re-read on 1 November (25). 25 open issues and 17 open pull requests on 8 October, most labelled and answered, with open reports of a race in transfer_task (#4156), a hand-off dropped silently (#4242) and edit_file editing the first of several matches (#3929), per the 8 October check, not re-read on 1 November (20). The changelog has Breaking Changes sections, but those changes ship in minor releases (1.114.0, 1.133.0 and 1.137.0 since July) and the major version has never moved. Since then 1.152.0 (21 October) made --auth-token mandatory on non-loopback API listeners under Bug Fixes, and 1.153.0 (28 October) removed MCP sampling, roots and logging support under Technical Changes and changed Go runtime packages in commits marked !, none of them in a Breaking Changes section (8). 1.154.0, past 1.0 (15).

smolagents 64

Local-package reading. Official PyPI package with Python 3.10 or newer (20). A public tests workflow runs pytest on Python 3.10 and 3.12 for pushes and pull requests; whether main passes wasn't read (15). 416 open issues and 1,045 open issues and pull requests on 6 November, with 144 issues opened in the 90 days to 3 November. Of the 50 newest, 26 had a comment and 1 was closed. Two 2026 CVE records say the vendor didn't respond to the reporter, and seven commits reached main from 8 August to 6 November (6). Release notes on GitHub tags but no changelog file, and the remote WasmExecutor was removed in a minor release (8). 1.0 since 31 December 2024 (15). 20+15+6+8+15 = 64.

Transparency & trust Docker Agent +16

Docker Agent 81

Apache-2.0 (30). The telemetry page lists what's collected and warns that arguments and error text can carry secrets or personal data. It doesn't name the endpoint (api.docker.com, per the source), link Docker's privacy policy or give a retention period, unchanged on 17 October (15). Breaking changes are dated in the changelog and one renamed variable kept a fallback for one release, with no written deprecation policy, and the changelog says frozen config schema versions aren't maintained long-term (10). Telemetry is disclosed in the README, the docs and a first-start notice, with an opt-out variable (20).

smolagents 65

Apache-2.0 (30). The library stores nothing itself; the default model sends prompts to Hugging Face's inference providers, which the docs show (20). Breaking removals such as WasmExecutor shipped in minor releases, without a written deprecation policy (5). No telemetry, though no page states it (12). 30+20+5+12 = 67.

Agent ergonomics Docker Agent +13

Docker Agent 81

Framework reading, scored on what an agent with MCP needs. The README's agent with one MCP server is eight lines of YAML and no code, with deferred toolsets and a code mode (23). Budgets cap cost, tokens and time, tool results are bounded to 50 KiB since 1.148.0, and context is compacted, but max_iterations is unlimited and no budget applies unless declared (16). --json writes one NDJSON event per message, tool call and error, and the API documents 404, 409, 413 and 502 responses. No exit-code reference found for run --exec (14). Sessions resume from SQLite, the event stream replays from a sequence number, follow-ups accept an Idempotency-Key, and read-only and destructive tool annotations drive the safety modes (18). One binary and a model key or a local model are enough to start. The library is Go only (10).

smolagents 68

Framework reading. MCPClient loads an MCP server's tools in a few lines (20). max_steps, planning intervals and final_answer_checks bound a run (16). Errors from tools and code go back to the model as observations (14). No built-in retry, idempotency or resume beyond replaying memory (8). Few required parameters and many providers, Python only, and the default model needs a Hugging Face token (10). 20+16+14+8+10 = 68.

Schema & documentation Docker Agent +9

Docker Agent 90

Framework reading. agent-schema.json in the repository is a JSON Schema for the whole config, and the chat server serves its OpenAPI document at /openapi.json. We found no OpenAPI document for the native /api server and didn't check the Go package reference (22). llms.txt on docker.github.io/docker-agent and on docs.docker.com (10). The docs say when to use the API server and when the chat server, compare six ways to pass large input, and state that permissions aren't a security boundary (17). Configs are parsed strictly, unknown fields fail to load with a hint, and safety fields accept four named modes only (13). An examples directory, a troubleshooting page of common errors and documented HTTP status codes for the API. We found no exit-code reference for run --exec (13). A dated CHANGELOG.md and a numbered config schema, now version 16, with migration on load (15).

smolagents 81

Framework reading. A typed Python API with reference pages for agents, models, tools and executors (22). llms.txt and Markdown pages on huggingface.co (10). The docs say when to use CodeAgent or ToolCallingAgent and when a sandbox is needed (17). Tools declare typed inputs in a schema dictionary or from a decorated function (12). Many runnable examples; error classes exist but aren't catalogued (10). Versions tagged with release notes, no changelog file (10). 22+10+17+12+10+10 = 81.

Verdicts

Docker Agent

An agent with an MCP server is eight lines of YAML, and the same file runs in a terminal, headless, or as an HTTP, MCP or A2A server. Usage telemetry is on by default and can carry prompts passed as command arguments, and breaking changes keep shipping in minor releases, two of them in October 2026 without a breaking label.

smolagents

A compact Python library for code-writing and tool-calling agents, with MCP tools, any model provider and remote sandboxes through E2B, Docker, Modal or Blaxel. The newest release is 1.26.0 of 29 May 2026, a critical remote-executor RCE took about eight weeks to fix, and the local executor isn't a security boundary.

Before you call either

Docker Agent

  1. Set TELEMETRY_ENABLED=false before run or exec with a prompt on the command line. Telemetry is on by default and sends positional arguments
  2. For unattended runs pass --safety restricted with an allow-list, or --sandbox. Without a policy, --exec rejects every tool call that needs approval
  3. Set max_iterations and a budget block in the config. Both are unlimited by default
  4. Run 1.130.0 or later. Earlier versions ran shell commands embedded in local skills, and A2A sessions before 1.126.0 skipped tool approval
  5. Review runtime.safety in any config pulled from a registry or URL. An author default of autonomous runs every tool call unprompted
  6. Pass --auth-token to serve api on any non-loopback address from 1.152.0, or it won't start. Don't rely on MCP sampling, removed in 1.153.0

smolagents

  1. Run CodeAgent with executor_type set to e2b, docker, modal or blaxel whenever the model or its inputs aren't trusted
  2. Use smolagents 1.24.0 or later to get the remote-executor deserialisation fix
  3. Set max_steps and final_answer_checks so a run stops on its own
  4. Pass structured_output explicitly to MCPClient to avoid the default-change warning
  5. Pin the version, since minor releases have removed APIs
