Effective Date: December 18, 2023
Timescale ultimately believes that open-source software produces higher-quality technology while providing transparency and flexibility to the developers that build on that technology. For these reasons, we are dedicated to developing TimescaleDB in the open and are making TimescaleDB available under the following licenses:
As of December 2018, we began categorizing features as Apache-2 or Community. Roughly speaking, as long as you are not offering TimescaleDB as a hosted Database-as-a-Service, you can use all Community features for free. For any questions, please contact [email protected].
PLEASE READ CAREFULLY THIS TIMESCALE LICENSE AGREEMENT ("TSL Agreement"), WHICH CONSTITUTES A LEGALLY BINDING AGREEMENT AND GOVERNS USE OF THE TIMESCALE TIME-SERIES DATABASE SOFTWARE AND RELATED SOFTWARE THAT IS PROVIDED SUBJECT TO THIS TSL AGREEMENT. BY INSTALLING OR USING SUCH SOFTWARE, YOU AGREE THAT YOU HAVE READ AND AGREE TO BE BOUND BY THE TERMS AND CONDITIONS OF THIS TSL AGREEMENT. IF YOU DO NOT AGREE WITH SUCH TERMS AND CONDITIONS, YOU MAY NOT INSTALL OR USE SUCH SOFTWARE. IF YOU ARE INSTALLING OR USING SUCH SOFTWARE ON BEHALF OF A LEGAL ENTITY, YOU REPRESENT AND WARRANT THAT YOU HAVE THE AUTHORITY TO AGREE TO THE TERMS AND CONDITIONS OF THIS TSL AGREEMENT ON BEHALF OF THAT LEGAL ENTITY AND THE RIGHT TO BIND THAT LEGAL ENTITY TO THIS TSL AGREEMENT.
This TSL Agreement is entered into by and between Timescale, Inc. ("Timescale") and you or the legal entity on whose behalf you are accepting this TSL Agreement ("You").
The Timescale time-series database software and related software is offered as "open code" or "source-available" code. This means that all source code of the software is available for inspection and download at https://github.com/timescale. The Timescale software is composed of two major pieces.
The first piece (referred to herein as the Timescale Open Source Software, as defined below) is open source software that is licensed under the Apache Version 2.0 license.
The second piece (referred to herein as the TSL Licensed Software, as defined below) is all of the Timescale Software other than the Timescale Open Source Software. The TSL Licensed Software may be used under this TSL Agreement without charge.
1.1 Source Code. The source code for all Timescale Software is made publicly available by Timescale at https://github.com/timescale. However, different license agreements govern the use of different parts of the Timescale Software source code. The use of Timescale Open Source Software, in both source and executable forms, is governed by the terms of the Apache License Version 2.0, a copy of which is available at https://opensource.org/licenses/Apache-2.0. The use of all other Timescale Software, in both source and executable forms, is governed by this TSL Agreement.
1.2 License Rights to Your Customers. As set forth in Section 2.1 below, the use by Your customers of the Timescale Software as part of any Value Added Products or Services that You distribute will be subject to the most current version of this TSL Agreement.
2.1 Grant. Conditioned upon compliance with all of the terms and conditions of this TSL Agreement, Timescale grants to You at no charge the following limited, non-exclusive, non-transferable, fully paid up, worldwide licenses, without the right to grant or authorize sublicenses (except as set forth in Section 2.3):
(a) Internal Use. A license to copy, compile, install, and use the Timescale Software and Derivative Works solely for Your own internal business purposes in a manner that does not expose or give access to, directly or indirectly (e.g., via a wrapper), the Timescale Data Definition Interfaces or the Timescale Data Manipulation Interfaces to any person or entity other than You or Your employees and Contractors working on Your behalf.
(b) Value Added Products or Services. A license (i) to copy, compile, install, and use the Timescale Software, Derivative Works, or parts thereof to develop and maintain Your Value Added Products or Services, (ii) to utilize (in the case of services) copies of the Timescale Software, Derivative Works, or parts thereof solely as incorporated into or utilized with Your Value Added Products or Services, and (iii) to distribute (in the case of products that are distributed to Your customers) copies of the Timescale Software binaries or of Derivative Works solely in binary form, and both solely as incorporated into or utilized with Your Value Added Products or Services; provided that (1) You notify Your customers that use of such Timescale Software or Derivative Works is subject to this TSL Agreement and You provide to each such customer a copy of the most current version of this TSL Agreement or a URL from which the most current version of this TSL Agreement may be obtained, and (2) the customer is prohibited, either contractually or technically, from defining, redefining, or modifying the database schema or other structural aspects of database objects, such as through use of the Timescale Data Definition Interfaces, in a Timescale Database utilized by such Value Added Products or Services.
(c) Distribution of Source Code or Binaries in Standalone Form. Subject to the prohibitions in Section 2.2 below, a license to copy and distribute the Timescale Software source code and binaries solely in unmodified standalone form and subject to the terms and conditions of the most current version of this TSL Agreement.
(d) Derivative Works. A license (i) to prepare, compile, and test Derivative Works of the TSL Licensed Software; (ii) to use Derivative Works for Internal Use solely as expressly permitted in Section 2.1(a); (iii) to utilize Derivative Works with Your Value Added Products or Services solely as expressly permitted in Section 2.1(b); (iv) to distribute Derivative Works in binary form with Your Value Added Products or Services solely as expressly permitted in Section 2.1(b); and (v) to distribute Derivative Works back to Timescale under Timescale's Contributor Agreement for potential incorporation into Timescale's maintained code base at its sole discretion.
2.2 Prohibitions. Notwithstanding any other provision in this TSL Agreement, You are prohibited from (i) using any TSL Licensed Software to provide time-sharing services or database-as-a-service services, or to provide any form of software-as-a-service or service offering in which the TSL Licensed Software is offered or made available to third parties to provide time-series database functions or operations, other than as part of Your Value Added Products or Services, or (ii) copying or distributing any TSL Licensed Software for use in any of the foregoing ways. In addition, You agree not to, except as expressly permitted in Section 2.1(d), prepare Derivative Works of any TSL Licensed Software or, except as expressly permitted herein, transfer, sell, rent, lease, sublicense, loan, or otherwise transfer or make available any TSL Licensed Software, whether in source code or binary executable form.
2.3 Affiliates and Contractors. You may permit Your Contractors and Affiliates to exercise the licenses set forth in Section 2.1, provided that such exercise by Contractors must be solely for your benefit and/or the benefit of Your Affiliates, and You shall be responsible for all acts and omissions of such Contractors and Affiliates in connection with such exercise of the licenses, including but not limited to breach of any terms of this TSL Agreement.
2.4 Proper Usage. At all times and in all oral, written or electronic communications, You will properly refer to your use of the TSL Licensed Software as “TimescaleDB Community Edition.” (For the avoidance of doubt, all usage of TimescaleDB Open Source should be properly referred to as “TimescaleDB Apache-2 Edition.”)
2.5 Reservation of Rights. Except as expressly set forth in Section 2.1, no other license or rights to the Timescale Software are granted to You under this TSL Agreement, whether by implication, estoppel, or otherwise.

(i) such value-added products or services are not primarily database storage or operations products or services;

In accordance with Section 6 below, Timescale shall have no liability for any damage, loss, or expense of any kind, whether consequential, indirect, or direct, suffered or incurred by You arising from or incident to the termination of this TSL Agreement, whether or not Timescale has been advised or is aware of any such potential damage, loss, or expense.
