## Which one, for what

### Aider (D)

Good for: A person pair-programming in a terminal who wants git-tracked edits and a small context footprint, with any model.

Ahead on:
- Security & auth, 59 against 42
- Payments & pricing, 60 against 30
- Transparency & trust, 65 against 60

Also in its favour:
- Free to start without a card

Watch for: No release since 0.86.2 in February 2026 and no commit since 22 May 2026

### Traycer (C)

Good for: Teams who want several coding agents working together with shared context and boards.

Ahead on:
- Reliability, 65 against 44
- Schema & documentation, 65 against 56
- Maintenance & community, 75 against 13

Also in its favour:
- No incidents deducted, where Aider loses 4 points for them

Watch for: Privacy Mode is opt-in for individuals; with it off, prompts may be logged


## Why the edge

### Maintenance & community: Traycer +62

- Aider (13): 0.86.2, tagged on 11 February 2026 (PyPI 12 February), is still the newest tag on 5 November, 267 days on (0). No release in the 90 days from 7 August (0). No commit on main since 2026-05-22 (5dc9490). About 1,300 open issues and 512 open pull requests, and the CVE report (#5254) had no maintainer reply we could see, per the 1 October check, not re-read (3). The PyPI package lags main, which declares Python 3.13 and 3.14 support that the release doesn't allow (5). CI ran on the last commits and dependencies are pinned, as of May (5). 0 + 0 + 3 + 5 + 5 = 13.
- 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.

### Payments & pricing: Aider +30

- Aider (60): No payment protocol (0). Free and Apache-2.0 with nothing to buy, so 20, 20 and 20 on the last three lines. Any model through LiteLLM, local ones included, with no signup.
- 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.

### Reliability: Traycer +21

- Aider (44): Read as a local package. aider-chat on PyPI, but the latest release (0.86.2, tagged 11 February 2026) requires Python below 3.13, while main declares 3.10 to 3.14 (18). The Ubuntu test workflow runs pytest on Python 3.10 to 3.14 on every push to main, and a Windows workflow sits beside it. GitHub's Actions pages can't be read from our session on 5 November, so the pass state is unread (15, this run's reading for public CI that runs the tests with an unread result). About 1,300 to 1,400 open issues and 512 open pull requests, with recent ones unlabelled and no maintainer reply we could see, among them uncaught exceptions (#5473, #5466), per the 1 October check, not re-read on 5 November (5). HISTORY.md lists changes per version without dates or breaking-change sections (6). 0.86, pre-1.0, and classed 4 - Beta (0). 18 + 15 + 5 + 6 + 0 = 44.
- 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.

### Security & auth: Aider +17

- Aider (59): Harness reading of the framework checklist, used for all five harnesses in this batch. 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. Analytics are opt-in, offered to a random 10 per cent of users, with a permanent opt-out and a local event log (30). Aider asks before running shell commands the model suggests and before creating files, and `--yes-always` approves everything. Edits apply without asking but each lands in a git commit. A `.aider.conf.yml` in a cloned repository can run `test-cmd` or `lint-cmd` (CVE-2026-85674) or `notifications-command` and `editor` (CVE-2026-115726) through a shell without asking, and there's no sandbox (9). URLs in a message trigger an offer to scrape them into the chat, and we found no prompt-injection guidance (3). Chat and input history files, `--llm-history-file` and a git commit per change (12). No SECURITY.md in the repository and no advisories published by the project. The open CVE report had a reply only from a contributor on 1 October (5). 30 + 9 + 3 + 12 + 5 = 59.
- 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.

### Schema & documentation: Traycer +9

- Aider (56): No machine-readable contract. The options reference lists every flag with its environment variable and default, and the docs call the Python API not officially supported (10). No llms.txt or Markdown versions of pages found in the site source (0). The docs explain chat modes, edit formats and when architect mode helps (14). Typed config through `.aider.conf.yml` and flags with defaults (10). Many usage examples and troubleshooting pages (12). A release history per version without dates (10).
- Traycer (65): Harness reading. Mintlify docs, a protocol package and a CLI (65).

### Transparency & trust: Aider +5

- Aider (65): Apache-2.0 (30). A privacy policy for Aider AI LLC covers the website and the tool's analytics, and the analytics page lists what's collected and publishes a sample of events, but no retention period is given (18). No deprecation policy or dated notices found (3). Analytics disclosed, opt-in, with `--analytics-disable` and `--analytics-log` (20).
- 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.

### Traycer

No score change since it was listed.

## Verdicts

**Aider.** Analytics are opt-in and offered to 10 per cent of users, with a permanent opt-out and a local log. No release since 0.86.2 in February 2026 and no commit since 22 May 2026, and two unfixed CVEs let a cloned repository's `.aider.conf.yml` run shell commands without a prompt.

**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

### Aider

1. Read `.aider.conf.yml` in any cloned repository before starting aider. Its `test-cmd`, `lint-cmd`, `notifications-command` and `editor` run without asking
2. Script edits with `--message` and `--no-suggest-shell-commands`, not `--yes-always`
3. Use Python 3.12 or earlier for the PyPI release
4. Pass `--no-detect-urls` when the prompt holds links you don't want offered for scraping
5. Check `git log` after a run. Each edit is its own commit

### Traycer

1. Turn on Privacy Mode if you're an individual user and don't want prompts logged
2. CLI agents you configure send requests straight to their provider; Traycer's own inference goes through Traycer
