Choosing an IoT platform is really a question about where your engineering team should spend its time. On rule engines, custom mobile apps, and data pipelines? Or on the product your customers actually pay for?
ThingsBoard is built around a powerful visual rule engine and flexible deployment options, from free self-hosting to managed cloud. Blynk is a fully managed platform that handles the connected product stack — no-code mobile app building, turnkey device provisioning, enterprise user management, and unlimited cloud infrastructure — so product teams can ship without building or maintaining backend systems. Both connect devices to the cloud and let you build dashboards. The real difference is what you build yourself versus what's handled for you.
Raypak, a commercial heating manufacturer since 1947, chose Blynk to connect their boiler and pool heater lines. Windmill Air shipped a 4.7-star consumer AC app using Blynk's no-code native app builder. These reflect a pattern: hardware OEMs and product companies that need to ship a connected experience to their customers, not manage an internal IoT operation, consistently land on Blynk.
ThingsBoard offers both self-hosted and managed cloud options. The managed cloud pricing scales with devices and data points:
The data point caps are worth paying attention to. Every telemetry value your device sends counts toward that monthly limit. At the Business tier, 1B data points across 1,000 devices works out to roughly 23 data points per device per minute. That's comfortable for many monitoring use cases, but higher-frequency deployments can easily exceed it.
ThingsBoard also offers self-hosted options: Community Edition (free, Apache 2.0) and Professional Edition (licensed by device tier). Self-hosting means you manage infrastructure but have complete control.
Blynk publishes straightforward pricing on its website:
All tiers include the cloud platform, mobile app builder, and device management. Prototype and above have no data point caps — your cost is predictable before you build, not discovered after you scale. Production scales on a simple sliding scale: $199 for 100 devices, with each additional 100 devices adding $100/month, up to 2,000 devices at $2,099/month. Production includes 12-month data retention, SMS alerting, a 99.95% SLA, and same-day support. Enterprise adds private infrastructure, dedicated support, and white-label mobile apps published under your company name on the App Store and Google Play. Blynk's cloud infrastructure is SOC 2 Type II compliant — a certification ThingsBoard has not publicly documented. Annual billing saves 20% across all paid tiers.
This is one of the most important cost differences between the two platforms, and it's easy to overlook until you're in production.
ThingsBoard Cloud tiers include data point caps. Every telemetry message your device sends, whether it's a temperature reading, a GPS coordinate, or a status update, counts toward your monthly limit. The caps range from 1M data points on the free tier to 1B on the Business tier. If your deployment exceeds these limits, you'll need to upgrade to a higher tier or move to self-hosting.
Blynk has no data point limits on Prototype and above. Your Prototype account at $99/month can ingest as much telemetry as your 50 devices can send. There's no metering, no overage fees, no surprises on next month's invoice — your devices can report at whatever frequency your product needs without redesigning your data strategy around cost.
Why this matters at scale: Consider a fleet of 500 environmental sensors reporting temperature, humidity, pressure, and air quality every 30 seconds. That's 8 data points per device per minute, or roughly 173 million data points per month. On ThingsBoard Cloud, you'd need the Startup tier ($399/month, 500M data point cap) at minimum. On Blynk, the Production tier covers 500 devices at $599/month with no data point ceiling. The pricing is close, but Blynk removes the risk of unexpected overage if your devices start reporting more frequently.
For low-frequency reporting (a few readings per hour), ThingsBoard's caps are generous and likely won't be an issue. But for anything involving frequent sensor reads, event-driven telemetry, or devices that stream data continuously, the math can shift quickly.
Self-hosting changes the equation. ThingsBoard Community Edition has no data point limits at all. If you have the infrastructure team to manage it, self-hosting removes this constraint entirely. More on that below.
Bottom line: If your devices send data frequently and you want managed cloud hosting, Blynk's unlimited model means you know the cost before you sign up. If your telemetry is infrequent or you plan to self-host, ThingsBoard's caps may never be a concern.
ThingsBoard takes a protocol-first approach. Devices connect via MQTT, HTTP, CoAP, or LwM2M using custom firmware you write yourself. This is flexible but means you're responsible for provisioning flows, OTA update mechanisms, and connection management from scratch.
Blynk provides native device libraries for popular MCU families (ESP32, Arduino, Raspberry Pi) that include BLE-assisted Wi-Fi provisioning, OTA firmware updates, and secure cloud connection out of the box. An ESP-IDF SDK adds production-grade support for teams building native ESP32 firmware. For devices using cellular connectivity or other protocols, Blynk supports MQTT and HTTPS integration. Data Converters let you connect devices without firmware changes by parsing incoming payloads into Blynk's data format, which is useful when integrating legacy or third-party hardware. This hybrid approach means hardware with native library support gets a turnkey experience, while anything else can still connect through standard protocols or Data Converters.
For remote deployments where cellular or satellite connectivity matters, Blynk supports a variety of cellular modules and SIM providers, with partnerships with satellite network providers including Iridium and Myriota for off-grid and remote deployments. Multi-network management covers Wi-Fi, Ethernet, and cellular. ThingsBoard supports cellular devices through its generic MQTT/HTTP layer, but there's no cellular-specific tooling, tested module support, or satellite connectivity.
ThingsBoard's rule engine is one of its core strengths.
ThingsBoard's rule engine is built around visual rule chains. You connect processing nodes in a drag-and-drop canvas to build complex data workflows. Filter incoming telemetry. Transform payloads. Route messages to different destinations based on conditions. Script custom logic using TBEL (ThingsBoard Expression Language) or JavaScript. The rule engine can aggregate data across multiple devices, trigger alarms based on complex conditions, and forward processed data to external systems like Kafka, RabbitMQ, AWS SNS/SQS, or Azure IoT Hub.
For teams building industrial monitoring, complex event processing, or multi-source data aggregation, this is a real capability. ThingsBoard's rule engine can handle scenarios that would require custom backend code on other platforms.
Blynk's automation system covers the most common monitoring and control scenarios without requiring rule chain engineering. You can set threshold-based alerts, scheduled actions, and device-to-device interactions: send a notification when temperature exceeds a limit, turn on a pump when soil moisture drops, trigger an action at a specific time. For production deployments where the automation logic is well-defined, this handles the operational layer. Blynk's Enterprise tier includes a more powerful rule engine with deeper configurability for teams that need complex automation workflows.
The tradeoff is complexity. ThingsBoard's rule engine has a meaningful learning curve. Building and debugging rule chains takes time, and mistakes in rule logic can cascade through your data pipeline. Blynk's automations are focused and predictable, covering the operational scenarios most production deployments need.
Raypak's commercial heating systems use Blynk's automations for temperature alerts and equipment status notifications: if a boiler exceeds safe operating temperature, notify the technician. Not every deployment needs multi-node rule chains.
Bottom line: If complex data processing and event-driven workflows are central to your product, ThingsBoard's rule engine has more depth. If your automation needs are standard monitoring, alerts, and control actions, Blynk's focused approach covers the operational layer while your team focuses on the product.
ThingsBoard Community Edition is free under the Apache 2.0 license. You can download it, deploy it on your own servers, and run it without licensing fees. That's a legitimate advantage for teams with the infrastructure expertise to make it work.
But "free software" doesn't mean free deployment. Here's what self-hosting actually costs.
Infrastructure. A production ThingsBoard deployment typically needs separate nodes for the application server, database (PostgreSQL + Cassandra or TimescaleDB for time-series data), message queue (Kafka or RabbitMQ), and a load balancer. For a moderately sized deployment, you're looking at 3-5 cloud instances or dedicated servers. On AWS, a basic production setup runs roughly $300-600/month in compute and storage before you account for data transfer, backups, or redundancy. High-availability configurations with failover can push that to $1,000+/month.
Operations. Someone has to keep it running. Patching, upgrades, backups, monitoring, security, scaling. If your team already manages Kubernetes clusters and production databases, the marginal effort is manageable. If self-hosting ThingsBoard would be your team's first serious infrastructure project, budget for at least a part-time DevOps role.
Upgrades. ThingsBoard releases updates regularly. Major version upgrades can involve database migrations and configuration changes. On managed cloud, this is handled for you. Self-hosted, it's your team's weekend project.
Where self-hosting makes sense: You need complete data sovereignty (regulatory requirements, government contracts). You're already running Kubernetes and have a DevOps team. Your scale is large enough that managed cloud costs exceed infrastructure costs. You need to customize the platform's source code.
Where it doesn't: You're a product team, not an infrastructure team. Your deployment is under 10,000 devices. You'd rather spend engineering time on your product than on keeping IoT infrastructure alive.
Blynk's managed cloud handles infrastructure, upgrades, security, and scaling — backed by a 99.95% SLA and SOC 2 Type II compliance. Self-hosting is available only at the Enterprise tier. If your primary motivation for self-hosting is cost savings at small to medium scale, the math often doesn't work out once you factor in operations. A single experienced DevOps engineer costs $180-230K loaded in the US — even Blynk's Enterprise subscriptions are a fraction of that. And SOC 2 Type II compliance and a 99.95% SLA aren't just convenience features. Many enterprise procurement processes require these certifications, and achieving them on self-hosted infrastructure is its own project.
Windmill Air chose Blynk's managed platform so their engineering team could focus on the AC product and customer experience rather than managing cloud servers.
Bottom line: ThingsBoard CE is free and capable. Self-hosting makes sense if you have the team for it and a reason beyond cost savings. For most product companies under 10,000 devices, managed cloud (from either platform) is more cost-effective when you account for the full picture.
Blynk customers include Raypak (commercial heating since 1947), Windmill Air (consumer AC with a 4.7-star app), OMIS (crane fleet monitoring), and StreetLeaf (smart infrastructure). Over 5,000 businesses and 1M+ developers across 136 countries use the platform across HVAC, agriculture, energy, and industrial monitoring.
ThingsBoard customers include the Schwarz Group (Lidl/Kaufland parent company) and deployments across manufacturing, energy management, smart buildings, and fleet management. The open-source Community Edition has a large developer community contributing integrations and extensions.
ThingsBoard and Blynk solve the same core problem differently. The right choice depends on what your team should be building versus buying.
Choose ThingsBoard if you have development resources and want maximum control. Custom mobile apps, complex rule processing, industrial protocols, self-hosted infrastructure. ThingsBoard gives you the building blocks and assumes you have the engineers to assemble them.
Choose Blynk if you're a product company that needs to ship a connected experience — not just connect devices to a cloud. No-code mobile apps (white-labeled at Enterprise), turnkey device provisioning, FOTA, enterprise-grade RBAC, AI-assisted development, Data Converters, satellite connectivity partnerships, SOC 2 Type II compliance, and managed infrastructure with unlimited messaging on Prototype and above. Production tier scales to 2,000 devices with 12-month data retention and same-day support. Blynk lets product teams spend engineering hours on what differentiates their product, not on IoT infrastructure.
Both platforms scale to production. The question is where your engineering hours are better spent — and whether you're building IoT infrastructure or building a product.

ThingsBoard Community Edition is free and open-source under Apache 2.0. You can self-host it without licensing fees. The managed cloud service (ThingsBoard Cloud) has paid tiers starting at $49/month. Professional Edition (self-hosted with premium features) requires a license.
Yes, but you'll need Flutter developers and you'll need to build more than the UI. ThingsBoard provides a Flutter SDK and a Mobile Center feature for configuration, but BLE provisioning, background MQTT connectivity, reconnection logic, and OTA updates are all out of scope. You'd build those yourself using community-maintained plugins. Blynk's no-code builder handles all of this natively — you design the interface and your customers access it through the Blynk app. At Enterprise tier, the app publishes under your brand as a standalone app. Blynk also offers a Mobile SDK at Enterprise for teams that want full custom control over the native app experience.
It depends on what you count as "cost." Blynk's subscription is all-in: infrastructure, security, compliance, upgrades, and support are included. ThingsBoard Cloud's subscription covers the software, but self-hosting adds infrastructure costs ($300-1,000+/month on AWS), an operations team, security compliance work, and upgrade maintenance. A single DevOps engineer costs $180-230K loaded in the US. So you're comparing a platform subscription against a platform subscription plus at least a partial engineering headcount.
ThingsBoard CE is genuinely free if your team already has the infrastructure expertise and capacity to absorb it. For teams that don't, Blynk's pricing is more predictable: no data point caps on Prototype and above, and Production scales to 2,000 devices at published rates.
Yes. Blynk supports 100+ device types, so most existing hardware can connect with firmware changes. The migration path depends on your current implementation, especially around rule engine logic and custom integrations.
Self-hosting is available at Blynk's Enterprise tier only. There is no free self-hosted option. Blynk is designed primarily as a managed cloud platform — for product teams that don't want to own infrastructure, that's a feature.
ThingsBoard has stronger SCADA capabilities with dedicated HMI dashboards, interactive SVG symbols, and Modbus/OPC-UA support via IoT Gateway. Blynk supports industrial protocols via Gateway API but requires more custom development. If SCADA is your primary use case, ThingsBoard is the more mature option. But "industrial IoT" is a broad category — if you're an industrial equipment OEM shipping connected products to customers rather than managing your own factory floor, Blynk's end-user app builder, white-labeling, and device provisioning are built for exactly that.
Blynk is built for companies that ship connected products to customers. No-code mobile apps with role-based views, BLE-assisted Wi-Fi provisioning, QR code device claiming, white-label app publishing, and enterprise-grade access control are all part of the platform. These are the capabilities that shape the end-user experience — the setup flow, the daily app interaction, the branded product touchpoint.
ThingsBoard is designed for teams managing their own assets: monitoring dashboards, rule-based automation, and operator-facing interfaces. It's strong for internal fleet management, but the customer-facing layer — native mobile apps, onboarding flows, white-label branding — is left to your engineering team to build.
