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.

Transparency & trust Paseo +15

Paseo 68

Apache 2.0 for everything but third-party components (30). No telemetry and agents run on your machine (22 of 30). CHANGELOG.md, no deprecation policy (10). States no telemetry (20). 30 + 22 + 10 + 20 = 82.

Vibe-Trading 53

MIT (30). There is no hosted service, so no privacy policy is needed. The README says where data lives (named Docker volumes or ~/.vibe-trading/), that broker keys go to the OS keyring and that generated code doesn't receive model or broker secrets. Nothing was found stating what reaches the model provider or the search fallbacks (15 of 30). Dated changelog entries, a Known issues section, an upgrade note for 0.1.10 and dated retirements such as mootdx leaving the default chain in October 2026. No deprecation policy or notice period (9 of 20). No telemetry was found in the source, but the docs do not state that nothing is collected (13 of 20).

Reliability Vibe-Trading +13

Paseo 50

Local software. Desktop builds, an Android APK, a Docker image and a Nix package (20). ci.yml 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). Version 0.15.3 (0). 20 + 15 + 0 + 15 + 0 = 50.

Vibe-Trading 63

Read with the local-software lines, as for nanobot and Agent Zero, since the owner runs it. vibe-trading-ai installs from PyPI for Python 3.11 or newer, with classifiers for 3.11 to 3.13, and a Docker Compose setup ships in the repository (20). A CI workflow runs the test suite on pushes and pull requests to main, with hash-locked dependency checks on Linux, macOS and Windows, and the repository holds 961 test files. Whether the latest runs on main passed couldn't be read, because GitHub's Actions pages weren't reachable (15 of 25). The repository page showed 7 open issues and 57 open pull requests on 25 October 2026, per that check (GitHub's pages answer 403 on 2 November), against 771 commits in the 30 days to 2 November, and the 0.1.18 notes list two known issues already fixed on main. Issue threads weren't read (18 of 25). CHANGELOG.md says it follows Semantic Versioning, with dated entries from 0.1.8, a Known issues section and an upgrade note for the LangChain 1.x move in 0.1.10, but on 0.x breaking changes ride in minor versions and there is no Breaking section (10 of 15). Version 0.1.18 with the classifier Development Status 4, Beta (0).

Security & auth Vibe-Trading +12

Paseo 58

Harness reading. The README says no telemetry, tracking or forced log-ins (30 of 30). Worktree per agent, on your own machine (10 of 20). No prompt-injection guidance (5). No audit log (5). SECURITY.md (8). 30 + 10 + 5 + 5 + 8 = 58.

Vibe-Trading 70

Harness reading used for nanobot and goose. 30 for 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. No telemetry code was found in the source at v0.1.18, and the only call to PyPI is the owner-run vibe-trading update. The API answers only loopback clients without API_AUTH_KEY, Docker binds 127.0.0.1 and runs as user vibe, and the MCP HTTP transport binds 127.0.0.1 with a Host and Origin allow-list against DNS rebinding but no token. Broker keys go to the OS keyring; model keys sit in agent/.env in clear text. The docs carry no statement that nothing is collected (24). Live orders need a mandate that only the owner commits through the web UI or API, with hard caps and a kill switch, and an optional TAP mode waits for human approval of each Alpaca write. No order tool is exposed over MCP, and shell tools are off on the API and every MCP transport unless enabled. The local CLI runs bash and file writes without asking, and generated backtest code runs as a network-capable subprocess with a narrowed environment and no sandbox (13). Reader and search tools add warning-only security_warnings from regex rules, and external MCP tool hints are treated as untrusted in the source. The claude-cli provider's tool filters are described as convenience filters, not a boundary (9). A live-action ledger written append-only with a hash-chained copy, run cards with hashed execution records, tool traces and per-run token usage (13). SECURITY.md with private advisory reporting and a five-business-day acknowledgement. Three advisories were published on 2 October 2026 with CVE identifiers, five months after the 0.1.7 fix, while the email TLS and cross-site settings fixes in 0.1.16 got none. No security.txt and no bounty (11). 24+13+9+13+11 = 70.

Schema & documentation Vibe-Trading +7

Paseo 65

Harness reading. Public docs, a CLI and plugin examples in the repository (65).

Vibe-Trading 72

Harness reading of the lines, as for nanobot. The MCP server's tools take typed JSON Schema inputs generated from Python signatures through FastMCP, with a string output schema, and the API server serves FastAPI's OpenAPI file locally (keyless on loopback, behind the key otherwise). No published OpenAPI file or tool manifest outside the running program (20 of 25). No llms.txt on vibetrading.wiki, where /llms.txt redirects to the home page, and the docs are drawn by script from content.en.js. The repository carries Markdown READMEs in seven languages and an agent skill file, agent/SKILL.md (5 of 10). Tool descriptions say what each does, its arguments and what to call first, such as list_skills() before load_skill. The server's own header says every tool is read-only apart from refresh_strategy_evidence, while write_file is also exposed (14 of 20). Inputs are typed, but many choices are free strings (protocol, risk_tier, format) and several take free dictionaries (8 of 15). Many worked examples in the README and a troubleshooting page that names failure states such as no_progress and the 403 from another device; tool errors come back as JSON with an error_type (12 of 15). Dated CHANGELOG.md, GitHub release tags and versioned docs, though the docs still name 0.1.16 as latest (13 of 15).

Maintenance & community Vibe-Trading +7

Paseo 75

v0.15.3 and commits on 7 November 2026 (30). More than three releases in 90 days (20). GitHub issues and pull requests weren't read (GitHub's pages refuse these sessions), so that line is scored absent (0). Current builds (15). CI on push (10). 30 + 20 + 0 + 15 + 10 = 75.

Vibe-Trading 82

v0.1.18 was tagged on 21 October 2026, 12 days before this check (30). Six releases in the 90 days from 4 August, 0.1.13 (tag 10 August) to 0.1.18, from the repository's tags; PyPI couldn't be read on 2 November (20). 771 commits on main in the 30 days to 2 November, 233 of them after v0.1.18, the last on 2 November; the 25 October repository page showed 7 open issues and 57 open pull requests, not re-read. Issue and pull request threads weren't read, a judgement call (18 of 25). An MCP server that isn't in the official MCP registry (searches for vibe-trading and hkuds on 2 November 2026 found nothing). It is published on PyPI, as a Docker setup and on ClawHub (5 of 15). Hash-locked requirements checked in CI on three operating systems, Dependabot set to monthly, and dependency floors raised for named CVEs, most recently on 29 October (9 of 10). 30+20+18+5+9 = 82.

Verdicts

Paseo

A self-hosted, open-source workspace for running many coding agents on your own machines, scriptable from the CLI and reachable from phone, web or desktop, with no telemetry or forced log-in. It's pre-1.0 and run largely by one maintainer.

Vibe-Trading

Vibe-Trading runs on the owner's machine under the MIT licence, ships near-daily fixes with a dated changelog, and keeps order tools out of its MCP server, with live orders gated by an owner-committed mandate. Three advisories, two critical, covered versions before 0.1.7, a 0.1.16 credential fix got no advisory, and the local CLI runs shell commands without asking.

Before you call either

Paseo

  1. Run the daemon on the machine that has your tools and credentials, and connect from the clients
  2. Script runs from the CLI for repeatable agent jobs

Vibe-Trading

  1. Run 0.1.16 or later. Earlier versions carry three published advisories, including unauthenticated API access with an RCE chain, and send the email password without checking TLS certificates
  2. Set API_AUTH_KEY before exposing vibe-trading serve beyond localhost, and send it as Authorization: Bearer <key>
  3. Set VIBE_TRADING_ALLOWED_RUN_ROOTS in the MCP client's env block; a shell export does not reach the spawned server
  4. Use vibe-trading run -p "..." --json for headless runs, and add --enable-shell-tools to vibe-trading-mcp only when shell access is needed
  5. Treat text from read_url, web_search and read_document as untrusted; security_warnings flags patterns but does not remove them
