Privacy Mode is opt-in for individuals; with it off, prompts may be logged
Why the edge
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.
Payments & pricing MiniMax Code +30
MiniMax Code 60
Self-hosted rule. No payment protocol (0). The CLI is free under MIT with nothing to buy (20). No card or MiniMax account is needed for the software, and BYOK works without a login (20). An agent can install it from npm and run mcode exec with a provider key and no sign-up (20). M Plan and MiniMax API usage are separate purchases. Total 60.
Traycer 30
Scored on the paid option, Traycer's own inference subscription, whose price wasn't read (0 of 20). No protocol (0). Bring-your-own-agent use is free (20). Accounts for sync and teams weren't checked, half (10). 0 + 0 + 20 + 10 = 30.
Schema & documentation MiniMax Code +16
MiniMax Code 81
Harness reading. mcode exec returns a versioned ExecResult JSON document (schemaVersion 1) or versioned stream-json events, takes --output-schema for the final answer, and mcode acp speaks the Agent Client Protocol. No OpenAPI, since there's no server API (20). llms.txt indexes the docs, and each page is served as Markdown (10). The security page says when to use each permission policy and to keep full and off to isolated workspaces, and the automation page gives a CI baseline (16). An options table with defaults and enums for permission, output and prompt modes (12). Examples for each mode, a nine-row exit-code table, five result statuses and a named error for invalid structured output (13). A dated CLI changelog in the docs, whose latest entry (0.7.0, 26 October) trails npm's 0.7.4 (10). Total 81.
Traycer 65
Harness reading. Mintlify docs, a protocol package and a CLI (65).
Security & auth MiniMax Code +15
MiniMax Code 57
Harness reading of the framework checklist. 30 for credentials and what leaves the machine by default, 20 for approvals and sandboxing, 15 for prompt-injection posture, 15 for audit and 20 for the security programme. Provider keys are read from an environment variable and never printed, and stored in config.yaml in the data directory. All three telemetry channels are off by default and the doc lists every field sent. The default smart policy classifies actions through a cloud classifier, and what it sends isn't documented (20). Ask, Auto and Full access in the TUI. Headless defaults to smart and fails on a pending permission request instead of approving it, while full and off skip checks. A bundled sandbox runtime with macOS tests, a read-only filesystem policy for Explore subagents when sandboxing is available, but the default sandbox coverage isn't documented (12). SECURITY.md says permissions and sandboxing don't replace review of untrusted plugins, MCP servers and shell commands. No guidance found for fetched web content (6). Sessions kept locally, /export with credential redaction, /transcript and stream-json events (11). SECURITY.md takes private reports by email and GitHub's private advisories with no response SLA, history and build scans with Gitleaks run in a release-audit workflow, and OSV lists no advisories for @minimax-ai/code or @minimax-ai/code-sdk. No security.txt (8). Total 57.
Traycer 42
Harness reading. Code is processed in memory and not used for training, but Privacy Mode is opt-in for individuals, prompts may be logged with it off, and Sentry and PostHog 'may be enabled in release builds' (10 of 30). No approval model described in the README (8 of 20). No prompt-injection guidance (5). No audit log found (5). SECURITY.md, CodeQL, Scorecard and secret scanning (14 of 20). 10 + 8 + 5 + 5 + 14 = 42.
Reliability Traycer +14
MiniMax Code 51
Local-package reading, for the CLI. An install script for macOS, Linux and WSL and one for Windows, and npm @minimax-ai/code with Node.js 22.19+, 24.2+, 25 or 26 stated. The installer doesn't support Alpine or musl (20). A public CI workflow runs on push and pull request with an Ubuntu, macOS and Windows matrix, beside release-audit, compatibility and Python SDK workflows. Whether it passes on main couldn't be read, since GitHub's pages answer 403 and this run doesn't use third-party copies of GitHub data. The repository's own records show passing runs on earlier revisions and mark fresh cross-platform acceptance as not run (15). Open issue counts and replies couldn't be read. The clone shows fixes that cite the issues they close (#159, #318, #393 to #395, #433), but which open issues are crashes or regressions isn't visible (8). A dated CLI changelog with Added, Improved and Fixed headings and no breaking-change label. Its latest entry is 0.7.0 (26 October) while npm's latest is 0.7.4 (30 October) (8). 0.7.x and called a source preview (0). Total 51.
Traycer 65
Local software. Builds for macOS, Linux and Windows, and package-manager publishing workflows (20). test.yml, CodeQL, OpenSSF Scorecard and secret scanning run on the repository; pass state not read (15). GitHub issues and pull requests weren't read (GitHub's pages refuse these sessions), so that line is scored absent (0). CHANGELOG.md (15). Host 1.5.3 (15). 20 + 15 + 0 + 15 + 15 = 65.
Agent ergonomics MiniMax Code +14
MiniMax Code 79
Harness reading, for a pipeline driving the CLI. Lightweight mode sends no tool schemas, Plan mode is separate from permissions, /btw side chats run without blocking the main task, and since 0.7.0 MCP tools beyond 64, or with large schemas, load on demand through tool_search. No per-tool allow or deny list was found in the CLI docs (16). json and stream-json output, --timeout, --max-steps, --output-schema and --output-last-message (18). Exit codes per failure class, a status field and an interaction error when a run would need a person (17). --session, --continue, fork and rewind, and a model request is retried when the first response doesn't arrive within 300 seconds (16). One positional argument runs a task and BYOK needs no MiniMax login. The TypeScript SDK @minimax-ai/code-sdk 0.1.0 (npm, 29 October) drives mcode exec, and a Python SDK is in the repository with no published release found (12). Total 79.
Traycer 65
Harness reading. Model switching within an agent, agent-to-agent loops, a CLI and cross-device sync (65).

Verdicts
MiniMax Code
An MIT-licensed terminal coding agent with a headless mode that returns versioned JSON, documented exit codes, an ACP server and a TypeScript SDK, and telemetry off by default. It's pre-1.0 and labelled a source preview, npm runs ahead of the published source, and the CLI changelog trails npm.
Traycer
An open-source app for running several coding agents together with shared context, agent-to-agent messaging and team boards, on every desktop OS. Privacy Mode is opt-in for individuals, and the README says Sentry and PostHog may be on in release builds.
Before you call either
MiniMax Code
- Run
mcode exec --cwd <repo> --output-format json --timeout 10m --max-steps 50and check both the exit code and the JSONstatus - Keep
--permission fullandofffor a container or throwaway workspace. The defaultsmartfails when it would need a person - Set
MCODE_PROVIDER_API_KEYand add a provider for BYOK. M Plan models need a browser sign-in withmcode login --region global - Set
MINIMAX_DATA_DIRper CI runner. Keys and sessions live in~/.minimaxby default - Pin a version. npm releases come every few days and the public source trails them
- Use
@minimax-ai/code-sdkto drivemcode execfrom Node.js. It's 0.x and its API may change between minor versions
Traycer
- Turn on Privacy Mode if you're an individual user and don't want prompts logged
- CLI agents you configure send requests straight to their provider; Traycer's own inference goes through Traycer
