## Which one, for what

### AstrBot (C)

Good for: Someone who wants one self-run bot answering on QQ, Telegram, Slack, Discord, Lark or WeCom, in private or group chats, with scheduled tasks, a knowledge base and plugins.

Ahead on:
- Reliability, 81 against 14
- Schema & documentation, 62 against 17
- Agent ergonomics, 54 against 9
- Payments & pricing, 60 against 10
- Maintenance & community, 81 against 17

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

Watch for: No approval step before any tool call. The agent sends messages, creates scheduled tasks and calls MCP tools without asking

### Gemini Spark (F)

Good for: A person who already keeps mail, calendar and files in a personal Google Account and accepts Keep Activity being on.

Ahead on:
- Security & auth, 60 against 44
- Transparency & trust, 49 against 40

Watch for: No public API, SDK or MCP server for an outside agent was found. Spark is reached in the Gemini mobile app, the Mac app and gemini.google.com

## Verdicts

**AstrBot.** Fourteen official messaging adapters, scheduled tasks and scoped API keys come in one AGPL-3.0 program with releases most weeks. No tool call asks for approval, no mail, calendar or long-term memory connector is built in, and usage statistics, including the machine's hostname, are sent by default.

**Gemini Spark.** Google's help pages state what Spark confirms before doing, how to delete its remote browser and code data, and the risks of prompt injection. Spark has no public API, Google calls it experimental, and it runs only with Keep Activity on, the setting under which chats are used for model training and human review.

## Before you call either

### AstrBot

1. Set `ASTRBOT_DISABLE_METRICS=1` before the first start. Statistics, including the hostname, are sent to tickstats.soulter.top by default
2. Set `dashboard.host` to 127.0.0.1 in `data/cmd_config.json`, or the `DASHBOARD_HOST` variable, unless remote access is intended. The default is 0.0.0.0
3. Create an `abk_` key in Settings, OpenAPI with only the scopes needed, and send it as `Authorization: Bearer` or `X-API-Key`
4. Include `username` in every `POST /api/v1/chat` body. Without the `chat:admin` scope an administrator ID is rejected
5. Check Extensions, Future Tasks after asking for a schedule. One-off tasks are deleted after their run even when the run fails

### Gemini Spark

1. Do not plan an integration against Spark. No public API or MCP server was found, and a person must hold a Google AI Pro or Ultra subscription
2. Expect a confirmation request before sends, edits, purchases and web form submissions, and note that bulk changes to private Google Tasks run without one
3. Delete remote browser data and remote code execution data in Gemini Spark Settings after a sensitive session. Deleting a task thread or Gemini Apps activity does not remove them
4. Keep within 15 running tasks and 50 active schedules. A schedule does not run when 15 tasks are running or the usage limit is reached
5. Treat every safety statement here as Google's own description. None was tested, and no message was sent to the service
