Parallax vs Traycer

Parallax 29

The review API has no OpenAPI or endpoint reference. Endpoints appear only in curl examples, and the base URL $PARALLAX_URL is not published (0). conifer.build/llms.txt covers the gateway in detail and Parallax in two lines that point to the docs (5). The docs explain sessions, sweeps, evidence states, memory and retention at length, but nothing documents the app, Captain, fallback or fast merge (8). parallax.yml keys are listed with allowed values (deliver: proven-only, review: off, severity floors, sweep modes), but request and response shapes for the API are not (5). curl examples, sample sweep lines and a table of skip reasons with the fix for each (8). Paths sit under /v1, with no changelog for Parallax (3).

Traycer 65

Harness reading. Mintlify docs, a protocol package and a CLI (65).

Parallax 40

Read as local software, because the launched product is the app the owner runs. A signed and notarised universal DMG for macOS 12 or later and Linux tarballs for x86-64 and arm64 on GitHub Releases, with SHA256SUMS and an install script. No package registry (20). The release repository holds a README and binaries only, with no public CI or tests (0). We could not read its issues, because our GitHub access refused the issue pages, so the issue record is unchecked and scored absent (0). Semver tags v1.0.0 to v1.0.2, but no release notes or changelog we could read (5). Version 1.0.2 (15). The hosted review service has no status page and no published rate limits. conifer.build/uptime covers upstream model providers only.

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.

Parallax 42

Scored on the review API and the hooks, the only parts an agent touches. The session-start brief is cut at 6,000 characters, memory per review call at 12,000, and lesson_cap sets 1 to 20 lessons per person (8). repo filters on recall and brief, brain=true on the ledger, no documented pagination (4). Skip reasons such as capture_commit_missing and test_configuration_missing each come with a fix, but HTTP error codes for the API are not documented (12). A session is swept once per capture mark, retries use no extra credit, and a fix PR is reused and never reopened or merged by Parallax (14). No SDK for Parallax, and capture of every repository is the default (4).

Traycer 65

Harness reading. Model switching within an agent, agent-to-agent loops, a CLI and cross-device sync (65).

Parallax 56

v1.0.2 on 16 October 2026 (30). Three releases, v1.0.0 to v1.0.2, on 15 and 16 October 2026 (20). Closed service. No public changelog. Support through a GitHub issues link, a Discord server and email, none of which we could check for replies (3). No Parallax SDK and nothing in the MCP registry. Conifer's SDK is for the gateway (0). Signed builds with checksums and a self-updater, with no CI to inspect (3).

Traycer 75

Commits on 6 November 2026 and host 1.5.3 (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 apps and CLI packages (15). CI with tests (10). 30 + 20 + 0 + 15 + 10 = 75.

Parallax 50

Closed source under Conifer's terms, which name the company, a Delaware corporation, and Delaware law (15). The privacy policy and docs agree on 30-day session retention, consent by installing capture, the upload opt-out and deletion by request. The policy predates the app and names only Claude Code and Codex for capture, while the docs also name Cursor, Cline and Prime (18). No deprecation policy. Conifer dated the retirement of its earlier desktop download page (1 September 2026), but nothing for Parallax (3). Fly.io is named as the Parallax subprocessor with US processing. Whether the Parallax app sends telemetry is not stated, and the self-updater's off switch is documented in the README (12).

Traycer 60

MIT (30). README privacy section and a linked privacy policy (not read) (18 of 30). CHANGELOG.md, no deprecation policy (10). Analytics described as 'may be enabled', with no opt-out given in the README (8 of 20). 30 + 18 + 10 + 8 = 66.
