Pricing Overview
LedgerMind is a fully open-source autonomous memory system for AI agents, available at no cost under its GitHub repository. The project operates under an enterprise pricing model where the core software is free to download, deploy, and modify. LedgerMind provides a complete autonomous knowledge lifecycle manager with a hybrid storage engine combining SQLite and Git, a built-in reasoning layer, and self-healing decay capabilities. Organizations can run LedgerMind on their own infrastructure without licensing fees. For teams requiring dedicated support, custom integrations, or managed deployment assistance, LedgerMind offers enterprise engagement on a contact-for-pricing basis. The current stable release is v3.3.5, published in March 2026, and the project remains actively maintained with the latest commit in April 2026.
Plan Comparison
LedgerMind follows a straightforward open-source model with enterprise support available for organizations that need it. Below is a breakdown of what each tier includes.
| Feature | Open-Source (Free) | Enterprise (Contact Sales) |
|---|---|---|
| Core memory engine | Included | Included |
| SQLite + Git hybrid storage | Included | Included |
| Built-in reasoning layer | Included | Included |
| Self-healing decay system | Included | Included |
| Conflict resolution | Included | Included |
| Multi-stage lifecycle (PATTERN to EMERGENT to CANONICAL) | Included | Included |
| Git-based cryptographic audit trail | Included | Included |
| Zero-Touch Automation | Included | Included |
| Deep Truth Resolution | Included | Included |
| Dedicated support | Community only | Priority support |
| Custom integrations | Self-service | Assisted setup |
| SLA guarantees | None | Available |
The open-source tier delivers the full feature set including autonomous knowledge lifecycle management, intelligent conflict resolution, and recursive supersede chain analysis. Every core capability ships in the free version. The enterprise tier adds organizational support infrastructure rather than feature gating, making LedgerMind accessible to individual developers and large teams alike. This model ensures that multi-agent systems and on-device deployments can leverage the complete memory engine without cost barriers.
Hidden Costs and Considerations
While LedgerMind itself is free, teams should budget for infrastructure costs. Running the SQLite and Git hybrid storage engine requires server resources that scale with the volume of stored knowledge entries. On-device deployment keeps costs predictable, but multi-agent systems with high memory throughput demand more compute and storage. Organizations should also factor in developer time for initial setup, ongoing maintenance, and version upgrades from the active release cycle.
How LedgerMind Pricing Compares
LedgerMind occupies a distinct position in the AI agents category by offering its full feature set at no cost. Most competitors in this space charge monthly subscription fees that scale with usage or team size. Here is how LedgerMind stacks up against other tools in the AI agents ecosystem.
| Tool | Pricing Model | Starting Price | Entry Tier Details |
|---|---|---|---|
| LedgerMind | Open-Source / Enterprise | $0 | Full feature set free; enterprise support on request |
| Clam | Usage-Based | $50/mo | Scales to $75/mo, $150/mo based on usage |
| LangChain | Freemium | $0/seat | Free developer tier; paid at $39/seat |
| Praes | Freemium | $24/mo | Free tier available; Pro at $59/mo |
LedgerMind stands out as the only tool in this comparison that delivers every feature without a paywall. Clam starts at $50/mo and scales to $150/mo for heavier usage, making it significantly more expensive for growing teams. LangChain offers a free developer seat but charges $39/seat for production use. Praes provides a free tier but gates its Pro features behind a $59/mo subscription. For teams that prioritize full-featured autonomous memory without recurring software costs, LedgerMind delivers the strongest value proposition in the AI agents category. The trade-off is the absence of managed hosting and guaranteed SLAs that paid platforms bundle into their subscriptions.
