  • 28. Grafana Loki

    Grafana Loki is a horizontally scalable and highly available multi-tenant log aggregation system inspired by Prometheus. Loki only indexes metadata about your logs as a set of labels for each log stream. Log data is stored in a block storage solution such as S3, GCS or Azure Blob Storage. The upshot is that Loki promises a reduction in operational complexity and storage costs over competitors. As you'd expect, it integrates tightly with Grafana and Grafana Alloy, although other collection mechanisms can be used.

    Loki 3.0 introduced native OpenTelemetry support, making ingestion and integration with OpenTelemetry systems as simple as configuring an endpoint. It also offers advanced multi-tenancy features, such as tenant isolation via shuffle-sharding, which prevents misbehaving tenants (e.g., heavy queries or outages) from impacting others in a cluster. If you haven't been following developments in the Grafana ecosystem, now is a great time to take a look as it is evolving rapidly.

  • 32. Weights & Biases

    Weights & Biases has continued to evolve, adding more LLM-focused features since it was last featured in the Radar. They are expanding Traces and introducing Weave, a full-fledged platform that goes beyond tracking LLM-based agentic systems. Weave enables you to create system evaluations, define custom metrics, use LLMs as judges for tasks like summarization and save data sets that capture different behaviors for analysis. This helps optimize LLM components and track performance at both local and global levels. The platform also facilitates iterative development and effective debugging of agentic systems, where errors can be difficult to detect. Additionally, it enables the collection of valuable human feedback, which can later be used for fine-tuning models.

  • 34. Chainloop

    Chainloop is an open-source supply chain security platform that helps security teams enforce compliance while allowing development teams to seamlessly integrate security compliance into CI/CD pipelines. It consists of a control plane, which acts as the single source of truth for security policies, and a CLI, which runs attestations within CI/CD workflows to ensure compliance. Security teams define workflow contracts specifying which artifacts — such as SBOMs and vulnerability reports — must be collected, where to store them and how to evaluate compliance. Chainloop uses Rego, OPA's policy language, to validate attestations — for example, ensuring a CycloneDX SBOM meets version requirements. During workflow execution, security artifacts like SBOMs are attached to an attestation and pushed to the control plane for enforcement and auditing. This approach ensures compliance can be enforced consistently and at scale while minimizing friction in development workflows. This results in an SLSA level-three–compliant single source of truth for metadata, artefacts and attestations.

  • 35. Deepseek R1

    DeepSeek-R1 is DeepSeek's first-generation of reasoning models. Through a progression of non-reasoning models, the engineers at DeepSeek designed and used methods to maximize hardware utilization. These include Multi-Head Latent Attention (MLA), Mixture of Experts (MoE) gating, 8-bit floating points training (FP8) and low-level PTX programming. Their high-performance computing co-design approach enables DeepSeek-R1 to rival state-of-the-art models at significantly reduced cost for training and inference.

    DeepSeek-R1-Zero is notable for another innovation: the engineers were able to elicit reasoning capabilities from a non-reasoning model using simple reinforcement learning without any supervised fine-tuning. All DeepSeek models are open-weight, which means they are freely available, though training code and data remain proprietary. The repository includes six dense models distilled from DeepSeek-R1, based on Llama and Qwen, with DeepSeek-R1-Distill-Qwen-32B outperforming OpenAI-o1-mini on various benchmarks.

  • 36. Deno

    Created by Ryan Dahl, the inventor of Node.js, Deno was designed to address what he saw as mistakes in Node.js. It features a stricter sandboxing system, built-in dependency management and native TypeScript support — a key draw for its user base. Many of us prefer Deno for TypeScript projects, as it feels like a true TypeScript run time and toolchain, rather than an add-on to Node.js.

    Since its inclusion in the Radar in 2019, Deno has made significant advancements. The Deno 2 release introduces backward compatibility with Node.js and npm libraries, long-term support (LTS) releases and other improvements. Previously, one of the biggest barriers to adoption was the need to rewrite Node.js applications. These updates reduce migration friction while expanding dependency options for supporting tools and systems. Given the massive Node.js and npm ecosystem, these changes should drive further adoption.

    Additionally, Deno’s Standard Library has stabilized, helping combat the proliferation of low-value npm packages across the ecosystem. Its tooling and Standard Library make TypeScript or JavaScript more appealing for server-side development. However, we caution against choosing a platform solely to avoid polyglot programming.

  • 40. Model Context Protocol (MCP)

    One of the biggest challenges in prompting is ensuring the AI tool has access to all the context relevant to the task. Often, this context already exists within the systems we use all day: wikis, issue trackers, databases or observability systems. Seamless integration between AI tools and these information sources can significantly improve the quality of AI-generated outputs.

    The Model Context Protocol (MCP), an open standard released by Anthropic, provides a standardized framework for integrating LLM applications with external data sources and tools. It defines MCP servers and clients, where servers access the data sources and clients integrate and use this data to enhance prompts. Many coding assistants have already implemented MCP integration, allowing them to act as MCP clients. MCP servers can be run in two ways: Locally, as a Python or Node process running on the user’s machine, or remotely, as a server that the MCP client connects to via SSE (though we haven't seen any usage of the remote server variant yet). Currently, MCP is primarily used in the first way, with developers cloning open-source MCP server implementations. While locally run servers offer a neat way to avoid third-party dependencies, they remain less accessible to nontechnical users and introduce challenges such as governance and update management. That said, it's easy to imagine how this standard could evolve into a more mature and user-friendly ecosystem in the future.

  • 43. Reasoning models

    One of the most significant AI advances since the last Radar is the breakthrough and proliferation of reasoning models. Also marketed as "thinking models," these models have achieved top human-level performance in benchmarks like frontier mathematics and coding.

    Reasoning models are usually trained through reinforcement learning or supervised fine-tuning, enhancing capabilities such as step-by-step thinking (CoT), exploring alternatives (ToT) and self-correction. Examples include OpenAI’s o1/o3, DeepSeek R1 and Gemini 2.0 Flash Thinking. However, these models should be seen as a distinct category of LLMs rather than simply more advanced versions.

    This increased capability comes at a cost. Reasoning models require longer response time and higher token consumption, leading us to jokingly call them "Slower AI" (as if current AI wasn’t slow enough). Not all tasks justify this trade-off. For simpler tasks like text summarization, content generation or fast-response chatbots, general-purpose LLMs remain the better choice. We advise using reasoning models in STEM fields, complex problem-solving and decision-making — for example, when using LLMs as judges or improving explainability through explicit CoT outputs. At the time of writing, Claude 3.7 Sonnet, a hybrid reasoning model, had just been released, hinting at a possible fusion between traditional LLMs and reasoning models.

  • 44. Restate

    Restate is a durable execution platform, similar to Temporal, developed by the original creators of Apache Flink. Feature-wise it offers workflows as code, stateful event processing, the saga pattern and durable state machines. Written in Rust and deployed as a single binary, it uses a distributed log to record events, implemented using a virtual consensus algorithm based on Flexible Paxos; this ensures durability in the event of node failure. SDKs are available for the usual suspects: Java, Go, Rust and TypeScript. We still maintain that it's best to avoid distributed transactions in distributed systems, because of both the additional complexity and the inevitable additional operational overhead involved. However, this platform is worth assessing if you can’t avoid distributed transactions in your environment.

  • 46. Synthesized

    A common challenge in software development is generating test data for development and test environments. Ideally, test data should be as production-like as possible, while ensuring no personally identifiable or sensitive information is exposed. Though this may seem straightforward, test data generation is far from simple. That's why we’re interested in Synthesized — a platform that can mask and subset existing production data or generate statistically relevant synthetic data. It integrates directly into build pipelines and offers privacy masking, providing per-attribute anonymization through irreversible data obfuscation techniques such as hashing, randomization and binning. Synthesized can also generate large volumes of synthetic data for performance testing. While it includes the obligatory GenAI features, its core functionality addresses a real and persistent challenge for development teams, making it worth exploring.

  • 48. turbopuffer

    turbopuffer is a serverless, multi-tenant search engine that seamlessly integrates vector and full-text search on object storage. We quite like its architecture and design choices, particularly its focus on durability, scalability and cost efficiency. By using object storage as a write-ahead log while keeping its query nodes stateless, it’s well-suited for high-scale search workloads.

    Designed for performance and accuracy, turbopuffer delivers high recall out of the box, even for complex filter-based queries. It caches cold query results on NVMe SSDs and keeps frequently accessed namespaces in memory, enabling low-latency search across billions of documents. This makes it ideal for large-scale document retrieval, vector search and retrieval-augmented generation (RAG) AI applications. However, its reliance on object storage introduces trade-offs in query latency, making it most effective for workloads that benefit from stateless, distributed compute. turbopuffer powers high-scale production systems like Cursor but is currently only available by referral or invitation.

  • 50. Tyk hybrid API management

    We've observed multiple teams encountering issues with the Tyk hybrid API management solution. While the concept of a managed control plane and self-managed data planes offers flexibility for complex infrastructure setups (such as multi-cloud and hybrid cloud), teams have experienced control plane incidents that were only discovered internally rather than by Tyk, highlighting potential observability gaps in Tyk's AWS-hosted environment. Furthermore, the level of incident support appears slow; communicating via tickets and emails isn’t ideal in these situations. Teams have also reported issues with the maturity of Tyk's documentation, often finding it inadequate for complex scenarios and issues. Additionally, other products in the Tyk ecosystem seem immature as well, for example, the enterprise developer portal is reported to not be backward compatible and has limited customization capabilities. Especially for Tyk’s hybrid setup, we recommend proceeding with caution and will continue to monitor its maturity.

Each edition of the Radar features blips reflecting what we came across during the previous six months. We might have covered what you are looking for on a previous Radar already. We sometimes cull things just because there are too many to talk about. A blip might also be missing because the Radar reflects our experience, it is not based on a comprehensive market analysis.
