Ahead on: - Reliability, 81 against 5 - Schema & documentation, 62 against 0 - Agent ergonomics, 54 against 0 - Security & auth, 44 against 4 - Payments & pricing, 60 against 0 - Maintenance & community, 81 against 58 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 ### Tab (F) Good for: A person who wants a texting assistant that browses, calls and buys with tight checkout controls. Ahead on: - Transparency & trust, 45 against 40 Watch for: Private beta behind a waitlist. ## Score by category | Category | Weight | AstrBot | Tab | Edge | | --- | --- | --- | --- | --- | | Reliability | 16% (20 this run) | 81 | 5 | AstrBot +76 | | Performance | 10%, pending | pending | pending | not scored in this run | | Schema & documentation | 13% (16.2 this run) | 62 | 0 | AstrBot +62 | | Agent ergonomics | 13% (16.2 this run) | 54 | 0 | AstrBot +54 | | Security & auth | 14% (17.5 this run) | 44 | 4 | AstrBot +40 | | Payments & pricing | 10% (12.5 this run) | 60 | 0 | AstrBot +60 | | Task success | 10%, pending | pending | pending | not scored in this run | | Maintenance & community | 7% (8.8 this run) | 81 | 58 | AstrBot +23 | | Transparency & trust | 7% (8.8 this run) | 40 | 45 | Tab +5 | | Negative events | ≤15 | -2 | 0 | | | **Total** | | **58.8 · C** | **10.7 · F** | | ## Facts side by side | Fact | AstrBot | Tab | | --- | --- | --- | | Kind | Agent harness | Platform | | Vendor | AstrBotDevs | Terrasoft, Inc. | | Hosted endpoint | no (local only) | no (local only) | | Transports | | | | Auth | OAuth or key | OAuth or key | | Pricing | Free | Paid | | x402 | no | no | | Licence | AGPL-3.0-or-later | Closed service under Tab's Terms of Use (Terrasoft, Inc., effective 2 September 2026). | | Read-only variant documented | no | no | | llms.txt | no | no | | Last release | 2026-09-27 | none | | Terms last updated | 2026-01-12 | | | Privacy policy last updated | no document linked | | | Customer content may train models | not found in the text | | | Terms restrict automated access | not found in the text | | | Terms restrict benchmarking | not found in the text | | | Terms or service can change without notice | not found in the text | | | Arbitration or class-action waiver | not found in the text | | | Popularity | 42k stars | none | ## 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. **Tab.** Tab is a private-beta texting assistant with a detailed security page on credential isolation and checkout binding, and a public updates page. No outside agent can call it, no price is published, and its privacy policy says nothing on training with user content. ## 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 ### Tab 1. Don't plan to call Tab from another agent. It answers only the owner's Messages or WhatsApp thread. 2. Tell the owner that access needs a waitlist place and no price is published. ## Questions ### Which is better for AI agents, AstrBot or Tab?

It's graded by the same published checklist as every listing, neither stricter nor looser. Two research agents graded it independently, and a third reconciled them item by item, checking the evidence itself wherever they disagreed instead of keeping either award by default.
