## 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:
- Agent ergonomics, 65 against 35
- Security & auth, 59 against 33
- Payments & pricing, 60 against 20
- Transparency & trust, 65 against 55

Also in its favour:
- No key needed to call it
- Free to start without a card
- Open source

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

### Verdent (E)

Good for: A person who wants a desktop app to plan and run several coding tasks at once, possibly on their own Claude Code or Codex.

Ahead on:
- Maintenance & community, 61 against 13

Watch for: No CLI, print mode, API or SDK, so a pipeline can't start or read a run except through a paired chat bot


## Why the edge

### Maintenance & community: Verdent +48

- 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.
- Verdent (61): Closed service. v2.18.0 on 29 October 2026, eight days before this check (30). More than three dated releases in the 90 days from 8 August, among them 2.10.0 to 2.18.0 (20). A dated public changelog, a support address, Discord and a subreddit, with no public tracker to read reply times (8). No official SDK or MCP server to keep current (0). No public packages or CI to judge (3). 30+20+8+0+3 = 61.

### Payments & pricing: Aider +40

- 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.
- Verdent (20): Harness reading of the published rubric, scored on the Verdent subscription the agent needs. No payment protocol (0). Plan prices from $5 a month, top-up prices and the credit value of about $0.059 are public without a login (20). Free Mode and the free trial ended on 29 October 2026, so there is no free tier (0). A person signs up in a browser (0). 0+20+0+0 = 20.

### Agent ergonomics: Aider +30

- Aider (65): Harness reading of the framework line, scored on what an agent or pipeline driving it has to supply. Aider doesn't use tool calls or MCP. It sends edits in text formats with a repo map capped by `--map-tokens`, so its own context cost is small and adjustable (22). `--map-tokens`, `--max-chat-history-tokens` and single-shot `--message` runs (14). Plain-text output, with no JSON mode or documented exit codes (8). Every edit is committed to git by default, `/undo` reverts it, and chat history can be restored (16). Python only, with an unofficial Python API and no MCP for adding tools (5).
- Verdent (35): Harness reading. MCP servers per project or globally, subagents, skills and rules, but no per-tool disabling or deferred loading found (10). No output-size, turn-limit or budget controls for a run were found beyond credit balances (5). No exit codes or error format, since there is no headless mode (3). Parallel workers in git worktrees and a review column make runs reviewable and reversible, with no resume by ID documented (10). No CLI, API or SDK. A pipeline can only reach Manager through a paired Telegram, Slack or Feishu bot (7). 10+5+3+10+7 = 35.

### Security & auth: Aider +26

- 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.
- Verdent (33): Framework reading (telemetry defaults, approvals, guardrails, sandboxing). Conversation history and tool results go to Verdent's US servers and on to Azure, Bedrock or Vertex, with zero data retention stated for Vertex and Bedrock only. Event logging to log.verdent.ai has no documented opt-out. BYOA keys stay on the machine (10). Plan Mode is read-only, Agent Mode asks before destructive commands and edits outside scope, and workers are isolated by git worktree, but there is no sandbox or network control and the approval list isn't enumerated (9). No prompt-injection guidance found, while web search and fetch results enter the context (2). Usage history in the dashboard, no audit log found (5). A security page with a disclosure address and a five-day acknowledgement, SOC 2 and ISO/IEC 42001 being pursued rather than held, no security.txt and no bug bounty (7). 10+9+2+5+7 = 33.

### Transparency & trust: Aider +10

- 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).
- Verdent (55): Proprietary, under terms from Verdent AI, Inc. that are clear on use and ownership (15). The privacy policy and security page agree that data stays in the US and that input isn't trained on without consent, and the security page lists subprocessors. The privacy policy gives no retention periods, names MiniMax as a provider the security list leaves out, and deletion is by email request (14). The credit bonus carries a promise of 15 days' notice, but Free Mode was retired on the day v2.18.0 shipped and no deprecation policy was found (6). Subprocessors and their locations are listed, and the domains the app calls are named, with event logging undescribed (12). 15+14+6+12 = 47.

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.

**Verdent.** A desktop and editor coding agent that splits a goal into parallel workers in git worktrees, with a read-only Plan Mode, MCP servers and the option to run workers on Claude Code or Codex. It has no CLI, API or sandbox, sends context through Verdent's servers, and has had no free tier since 29 October 2026.

## 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

### Verdent

1. Don't plan to drive Verdent headless. Hand the task to the person using the desktop app, or use a harness with a print mode
2. Start large changes in Plan Mode and review plan.md before switching to Agent Mode
3. Add MCP servers in the project's .mcp.json or ~/.verdent/mcp.json in the mcpServers shape
4. Keep work under git, since rollback relies on git and there is no sandbox
5. Budget in credits at about $0.059 each, because there is no free allowance since 29 October 2026
