Arc is a high-performance, open-source time-series database built for Industrial IoT, fleet tracking, and sensor data at scale. Ingests 9.47M records/sec and stores data in portable Apache Parquet format, enabling seamless querying with DuckDB, pandas, Spark, and BI tools. Zero vendor lock-in with S3-compatible storage and AGPL 3.0 license.
After years of watching InfluxData customers struggle with vendor lock-in, proprietary storage formats, and expensive migration projects, we built Arc differently. Arc is an open-source time-series database that stores your data in Apache Parquet, the industry-standard columnar format used by Snowflake, Databricks, and BigQuery. This architectural decision means your time-series data works with DuckDB, pandas, Spark, and any modern analytics tool without export steps, format conversions, or vendor-specific APIs.
Arc delivers production-grade performance with 9.47M records/sec sustained ingestion and sub-second analytical queries on billion-row datasets. The database combines DuckDB's vectorized execution engine with intelligent partition pruning and columnar projection to minimize I/O. Deploy on AWS with S3 or EBS storage, integrate with Grafana for dashboards, and ingest data via Telegraf (300+ source plugins), REST API, or direct SDK writes. Arc excels at Industrial IoT workloads including fleet tracking, smart city sensors, manufacturing telemetry, and infrastructure monitoring where both fast writes and analytical queries matter.
Unlike proprietary time-series databases that create data gravity through custom formats, Arc ensures data portability from day one. Your data scientists can query historical data with pandas notebooks, your data engineers can build Spark pipelines, and your analysts can connect Tableau, all reading the same Parquet files Arc writes. For production deployments requiring enterprise support, SLA guarantees, or architecture consulting, contact support@basekick.net. Arc is AGPL 3.0 licensed with 400+ GitHub stars and 150+ production deployments worldwide.

Built for Industrial IoT: Production-proven for fleet tracking, smart city sensors, manufacturing telemetry, and high-volume time-series workloads with S3/EBS storage support
AWS Marketplace now accepts line of credit payments through the PNC Vendor Finance program. This program is available to select AWS customers in the US, excluding NV, NC, ND, TN, & VT.
You run Arc on your own AWS EC2 instances, and the software itself is free. Pricing here reflects the hourly EC2 compute you choose, not a license fee. Five instance sizes are available. The t3.large fits smaller or test workloads. The m8a family scales up through xlarge, 2xlarge, 4xlarge, and 8xlarge, each adding more CPU and memory. You pick the size that matches your ingestion and query load, and you pay per hour for the instance you select. Larger instances handle heavier data volumes.
Top-of-mind questions for buyers
Am I charged for the software itself, or only for the EC2 instance I run it on?
The Arc software is free under an open-source license. You pay only the hourly rate for the EC2 instance size you select. When the instance runs, hourly charges accrue. When you stop the instance, hourly compute charges stop, though AWS storage fees for attached volumes may still apply.
How do the five instance sizes differ, and what drives the cost difference between them?
Each size maps to an EC2 instance with set CPU and memory. The t3.large suits smaller or test workloads. The m8a sizes scale up through xlarge, 2xlarge, 4xlarge, and 8xlarge, adding more CPU and memory. You pay per hour, so heavier instances cost more per running hour.
If my data volume grows, how do I move to a larger instance?
Arc separates compute from storage, keeping data in Parquet files on object storage such as AWS S3. You can select a heavier instance size when ingestion or query load rises. Because storage is decoupled, scaling compute does not require moving your data.

An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.
