Spacebot: review, pricing, security and alternatives

What Spacebot does

Spacebot belongs to the personal assistants family: general-purpose agents, often self-hosted and driven from a messaging app, that act for you on your files, accounts and services. On our grid it ranks #38 of the 46 projects of this family listed in the directory.

You use it from: messaging (Telegram, Slack, WhatsApp…). It can run on your own machine or server.

Who is Spacebot for?

It targets individuals and freelancers who want an assistant able to act for them day to day, often from a messaging app. Typical tasks people give it:

• sort e-mail and draft replies
• manage a calendar and reminders
• look up information and summarise it
• run small recurring tasks

It is a good candidate if you want to talk to it from your usual messaging app, without opening another app and your data must stay on your machines.

Access and human control

According to its documentation, Spacebot can:

• read and send messages

We could not establish whether it asks for human approval before sensitive actions: test it first on an unimportant account or folder.

Spacebot pricing

The code is public but the repository declares no licence: reuse is not formally allowed. The real cost comes from model calls: each loop step sends the whole context back to the model, and a task of several dozen steps can cost far more than a single question. The LLM price calculator estimates it for the chosen model.

Getting started with Spacebot

1. Install it: the project ships as a compiled Rust binary (direct download or cargo install). The exact command is in the repository README.
2. Create an API key with the model provider and put it in an environment variable, never in a shared or versioned file.
3. Give it a first playground with nothing at stake: a test folder, a secondary account or a throwaway project. Only open your real accounts once you have seen how it behaves.
4. Give it a short, checkable task, review the result and its action log, then raise the difficulty step by step.

Security: risk level

A personal assistant often combines access to private data, reading outside content and sending messages: the combination that enables data leaks through prompt injection.

Points found for Spacebot:

• No licence: legally shaky for company use.

Three habits: least privilege (minimal rights, dedicated keys), human approval for irreversible actions, a sandbox for code execution. The AI agent security check reviews your setup in a few minutes.

Spacebot vs other personal assistants

GitHub stars of the best-rated open-source projects in the personal assistants family. Stars measure attention, not quality: a heavily promoted project collects them fast, a specialised tool will have few.

Spacebot and other personal assistants at a glance

The 7 best-ranked agents in the same family, 7 of them open source. The score out of 100 only applies to open-source projects; for proprietary services we show the published entry price. A dash marks information the documentation does not state.

How we rated it

Score: 51/100, computed only from public, verifiable data, with no subjective testing or partnership:

• Adoption 17/40: 2,421 stars on a log scale (40 points from about 200,000).
• Activity 24/30: last commit 1 month ago, 1 release in six months, 1,370 commits in a year.
• Framework 10/30: licence, default human approval, self-hosting, model choice and documentation site.

The score does not say whether the agent will succeed at your tasks: it measures how solid the project is. The full grid is on the method page.
