Common questions about Spora. If your question isn’t here, ask in GitHub Discussions.

Installation

Q: What’s the minimum PHP version?

PHP 8.4 or later. The codebase uses readonly properties, enums, and the FrankenPHP-targeted FrankenPHP runtime. PHP 8.3 and earlier won’t work — the Composer platform check fails the install.

Q: Do I need a database?

SQLite by default (no setup). For MySQL/MariaDB, set SPORA_DB_* env vars before bin/spora spora:install. See Install for the 5-route install matrix.

Q: Can I run Spora on a shared host without root?

Yes — that’s the original target. cPanel/Plesk/FTP-only hosts with PHP 8.4+ work. See Shared host for the step-by-step.

Q: Can I run Spora without Docker?

Yes. Use the Classical server path (nginx + PHP-FPM + systemd + supervisord), or the Shared host path (cPanel-style). Docker is just a convenience.

Plugins

Q: Where do plugins come from?

Plugins ship as Composer packages of type: "spora-plugin". The Spora org publishes a starter template (spora-plugin-skeleton) and nine production plugins (Tavily, Serper, Semantic Scholar, World News, Weather, Calendar, Email, MiniMax, Zernio). Anyone can author one — see Author guide.

Q: How do I install a plugin?

CLI: php bin/spora plugin:install vendor/package. Web UI: Plugins → Browse → Install (requires SPORA_PLUGIN_INSTALL_ENABLED=true). For local development of a plugin you author, the recommended workflow is a Composer path repository. See Install API for the full contract.

Q: How do I author my own plugin?

See Develop → Plugins → Author guide — the canonical Hello-Tool walkthrough, the plugin.json schema reference, and the PSR-4 entry-point rule. The Plugin skeleton is the starting template.

Q: Can I package project-local code as a plugin later?

Yes — it’s a mechanical rename + manifest addition, not a rewrite. See the Promoting an App to a Plugin section in Customization.

Security

Q: How are tool credentials encrypted?

SPORA_SECRET_KEY (32-byte base64) is the master key. Tool credentials are encrypted at rest using libsodium secretbox (XSalsa20 stream cipher + Poly1305 MAC, AEAD). See Security for the full algorithm and key-resolution chain.

Q: Is the operator’s data sent to Spora’s authors?

No. Spora is self-hosted — operator runs their own Spora instance. There are no telemetry, no phone-home, no analytics. The only outbound network calls are the ones the operator configures (LLM provider, IMAP, calendar, etc.).

Q: Can the operator audit agent actions?

Yes. Every tool call is recorded in tool_calls (input, output, approval, timestamp, agent, user, task). Every task is recorded in tasks with its full task_history. The admin UI has an audit log view (if enabled). The underlying SQL tables are accessible directly via php bin/spora db:reset etc.

Performance

Q: How fast is Spora?

For single-instance deployments, the bottleneck is the LLM API call (200-2000 ms typical), not the framework. Spora’s per-turn overhead is ~10-50 ms (DB write, history append, tool dispatch). The async worker mode (SPORA_SYNC_MODE=false) lets multiple tasks run concurrently on a single host.

Q: Can Spora run on a Raspberry Pi?

Yes for SQLite + small local models. No for hosted Claude/GPT-4 at production scale — the LLM provider’s rate limits become the bottleneck before Spora does.

Q: How many concurrent agents can run?

Bounded by SPORA_MAX_WORKERS (default 0 = unlimited) and your database’s connection pool. SQLite handles single-writer; MySQL handles many concurrent writers. The single-instance flock lock at storage/spora-worker.lock ensures only one worker process per host.

Operations

Q: How do I update Spora?

composer update spora-ai/spora-core (and spora-frontend if you have it as a path repo), then php bin/spora spora:install to apply any new migrations. No downtime if you use worker mode; brief downtime for sync mode.

Q: How do I back up Spora?

For SQLite: copy storage/database.sqlite + storage/secret.key + .env. For MySQL: mysqldump + storage/secret.key + .env. See Backups for the full strategy.

Q: Can I run Spora on Kubernetes?

Yes — there’s no Spora-specific K8s operator, but a Deployment + Service + PVC + a worker Deployment works. Use the Docker — multi-container image as the base. The single-instance flock is a per-host constraint — run one worker per node, scale horizontally by adding nodes.

Licensing

Q: What license is Spora under?

MIT. See License.

Q: Can I use Spora commercially?

Yes. MIT permits commercial use, modification, and distribution, with attribution.

Q: Are the plugins under the same license?

Each plugin is independently licensed. The Spora org plugins are all MIT, but third-party plugins can be any OSI-approved license.
